Early Removal of Indwelling Catheter and Vaginal Pack After Vaginal Prolapse Surgery: A Retrospective Cohort Study.

After vaginal pelvic organ prolapse (POP) surgery a vaginal pack and indwelling bladder catheter are inserted to reduce blood loss and bladder overdistension. The ideal timing of removal remains unclear. In this study we compared removal of vaginal pack and indwelling catheter 3 h post-surgery with removal the next day. This retrospective cohort study performed in the Netherlands included patients undergoing POP surgery between 1 January 2019 and 31 December 2020. Patients in whom the vaginal pack and catheter were removed the day after surgery (group A) were compared with patients in which the vaginal pack and catheter were removed 3h post-surgery (group B). Both groups were compared regarding urinary retention and the need for re-intervention owing to active blood loss within 6weeks postoperatively. Baseline characteristics, such as age, type of operation and type of anaesthesia in group A (n = 280) and group B (n = 207) were comparable. No significant differences were found regarding complications such as urinary retention (17.2 versus 23.2%; p = 0.255). The rates of re-intervention because of active blood loss and occurrence of infection were also comparable. Removal of the indwelling catheter and vaginal pack 3h after vaginal POP surgery does not lead to more postoperative complications than removal the 1st day after surgery. Therefore, early removal is a feasible and safe alternative to the standard timing of removal the morning after surgery of women undergoing POP surgery. In the future this could help with introducing same-day discharge.

Cannulated screws fixation for nondisplaced femoral neck fractures: early versus late weight-bearing-a prospective analysis.

Nondisplaced intracapsular fractures (Garden I/II) are predominantly treated with an internal fixation technique. The purpose of the study is to identify the best rehabilitation protocol after internal fixation with 3 parallel cannulated screws. All patients operated on from 2016 to 2021 for femoral neck fractures by internal fixation with 3 cannulated screws were enrolled into this prospective study. The population was divided into two groups: Group A (n = 34) who followed a postoperative rehabilitation protocol involving full and immediate loading, and Group B (n = 22) who followed a postoperative rehabilitation protocol involving late full loading (after 30days). The two groups were compared with each other by mortality rate, postoperative complications and need for re-interventions. Functional outcome and quality of life were assessed at the minimum follow-up of 1year using the modified Harris Hip Score(HHS) and the Short form health survey (SF-12) questionnaire. Group A showed a lower complication rate (2.9% vs. 18.2%), a lower 1-year mortality rate (5.9% vs. 9.1%), a better perception of mental health status (SF12-MCS 56.2 vs. 51.4, p = 0.03) but a worse perception of one's physical health status (SF12-PCS 48.1 vs. 56.7, p < 0.01). The two groups were also statistically overlapping in terms of the functional outcome achieved after the intervention (HHS was 90.94 in Group A vs. 93.15 in Group B, p = 0.32). Postoperative complications, mortality and revision rate were higher in patients who followed a late-loaded rather than early loaded rehabilitation protocol. Functional outcome at 1-year survival is not significantly different. In nondisplaced intracapsular hip fractures treated with cannulated screws, an immediate full load should be preferred. Query.

The Value of Aortic Volume and Intraluminal Thrombus Quantification for Predicting Aortic Events after Endovascular Thoracic Aneurysm Repair.

Objectives: To assess the ability of the aortic aneurysm volume (AAV), aneurysmal lumen volume (ALV), and aneurysmal thrombus volume (ATV) to predict the need for aortic reintervention when using the maximal aortic diameter as a reference. Methods: This monocentric retrospective study included 31 consecutive patients who underwent successful thoracic endovascular aortic repair (TEVAR) to treat an atheromatous thoracic aortic aneurysm. All patients underwent clinical and computed tomography angiography (CTA) for 3 years after TEVAR. The patients were categorized into group 0 if no aortic reintervention was required during the follow-up period and categorized into group 1 if they experienced a type I or III endoleak or aneurysm diameter increase requiring intervention. The maximum aneurysm sac diameter and the AAV, ALV, and ATV were calculated using CTA images obtained preoperatively (T0) and at 6-12 months (T1), 24 months (T2), and 36 months (T3) postoperatively, and their changes over time were analyzed. Correlations between diameter and changes in AAV, ALV, and ATV were assessed, and the association between diameter and volume changes and reintervetion was examined. The cutoff values for predicting the need for reintervention was determined using a receiver operating characteristic (ROC) curve. The accuracy of volume change versus diameter change for predicting the need for reintervention was analyzed. Results: There were no significant differences in terms of the mean aneurysm diameter or AAV, ALV or ATV between the groups at preoperative CTA or after one year of follow-up imaging. The mean ATV was higher in group 1 than in group 0 at 2 years (187.6 ± 86.3 mL vs. 114.7 ± 64.7 mL; p = 0.057) and after 3 years (195.0 ± 86.7 mL vs. 82.1 ± 39.9 mL; p = 0.013). The maximal diameter was greater in group 1 than in group 0 at 3 years (67.3 ± 9.5 mm vs. 55.3 ± 12.6 mm; p = 0.044). The rate of AAV change between T0 and T1 was significantly higher in group 1 (7 ± 4.5%) than in group 0 (-6 ± 6.8%; p < 0.001). The rate of ATV change between T1-T3 was significantly higher in group 1 than in group 0 (34 ± 40.9% vs. -13 ± 14.4% (p = 0.041)); similar results were observed for the rate of ATV change between T2 and T3 (27 ± 50.1% for group 1 vs. -8 ± 49.5% in group 0 (p < 0.001)). According to our multivariate analysis, the annual growth rate for AAV between T0 and T1 was the only independent factor that was significantly associated with aortic reintervention (area under the curve (AUC) = 0.84, OR = 1.57, p = 0.025; optimal cutoff +0.4%). An increase in the annual growth rate of the ATV between T0 and T3 was independently associated with the need for aortic reintervention (area under the curve (AUC) = 0.90, OR = 1.11, p = 0.0347; optimal cutoff +10.1%). Conclusions: Aortic volume analysis can predict the need for aortic reintervention more accurately and earlier than maximal aortic diameter.

Long-term impact of coronary artery transfer techniques during the arterial switch operation on neo-aortic root dilation

BackgroundAortic dilation (AD) remains one of the most common complications needing re-operation after ASO (arterial switch operation) in simple transposition of the great arteries (TGA). ObjectivesWe sought to clarify which coronary artery transfer techniques help to minimize postoperative neo-aortic root dilation after ASO for TGA. Methods117 patients were identified in the German National Register for Congenital Heart Defects presenting transposition of the great arteries with intact ventricular septum (TGA-IVS) with minimum 5-year follow-up who underwent ASO between 1986 and 2015 at 16 centers. Our study population was divided into two groups depending on the sinus tissue gain during coronary re-implantation. Group one (n = 72) included the tissue-gaining techniques slit, trap-door, J-/V-/U-incision, and pericardial augmentation. Group two (n = 45) included ‘punch’ as the no-tissue gaining technique. Transthoracic echocardiography data were analyzed retrospectively for development of neoaortic dilation defined by Z-score ≥ 2.0. As secondary endpoint was analyzed, the need for reintervention due to aortic pathology. ResultsMedian follow-up was 11 (5–29) years; cumulative follow-up was 853 patient-years for group one and 19 (5–34) years; cumulative follow-up was 853 patient-years for group two, comprising 1706 patient-years, p < 0.0001. We observed statistically significant higher Z-scores at the aortic valve annulus level in group one (p = 0.03). There was no statistically significant difference between both groups regarding re-operation. ConclusionNeo-aortic roots of patients who underwent sinus gain tissue coronary artery transfer techniques show higher Z-scores than the punch technique in long-term postoperative follow-up. Lifelong surveillance of patients after ASO seems necessary.

Comparison of Three Antibiotic Prophylaxis Protocols for Preventing Postoperative Infection in Tibial Plateau Fractures

Background: The aim of this study was to compare the impact of three different types of intraoperative antibiotic prophylaxis on the risk of postoperative surgical site infection (SSI). Material and Methods: Single-center retrospective cohort study. Patients who underwent surgery for osteosynthesis of a tibial plateau fracture (January 2009–November 2018) in Hospital Clinic i Provincial de Barcelona were included. Three types of prophylaxis during the study period were used: group A (cefuroxime single-dose treatment), group B (meropenem + teicoplanin), and group C (ceftriaxone + teicoplanin). Demographics, co-morbidity, type of fracture, need for external fixation, microbiology data, surgical time, and outcome were recorded. Failure was defined as the need for reintervention due to postoperative surgical site infection. Results: From a total of 148 patients included, 20 cases developed SSI, 8 from group A, 8 from group B, and 4 from group C. Higher ASA scores, Schatzker II classification, need for external fixation, and a prolonged surgical time were associated with a significantly (p &lt; 0.005) increased incidence of SSI. Group C showed the overall highest survival and lowest cumulative risk, but differences were not statistically significant. Conclusions: Group C showed the lowest incidence of infection in this sample. It is necessary to confirm these findings with larger studies.

Long-term results of the tuberous breast: What to expect after the primary correction process?

Tuberous breast is a rare anomaly affecting the development of mainly the female breast. It presents with varying degrees of hypoplasia in the breast base and skin. In some cases, herniation and widening of the areola is observed. The condition constitutes a great challenge for the reconstructive surgeon. In this study, the surgical cascades of implant and lipofilling corrections were compared with a focus on the need for re-interventions. In total, 129 patients whose treatment regimen started between January 2010 and October 2020 were included in this study. Patients were categorized into two groups based on the volume correction method used (lipofilling versus implant). In 35 (27%) patients (41 breasts), breast volume increasement was executed with an implant, while 94 (73%) patients (169 breasts) underwent volume increasement with lipofilling. The mean number of operations during the primary correction process was 1.2 (range 1-5) for the implant group and 2.4 (range 1-5) for the lipofilling group. When assessing the need for re-operations within 5 years after completing the primary correction, 46% of patients in the implant group needed further surgeries, while the corresponding proportion for the lipofilling group was 21% (p = 0.04). There were six major complications, all of them in the implant group. Implant-based reconstruction is associated with more revision surgeries and major complications compared to autologous lipofilling corrections. Lipofilling offers a more durable result with less re-operations over time despite initial sequential primary surgeries.

Angioplasty with ductal stent: experience at Garrahan Hospital

To describe and evaluate the outcomes of ductal angioplasty with stent placement at a single high-complexity center during the period 2016-2022. A retrospective descriptive cross-sectional study was conducted, including patients under 3 months of age who underwent ductal stent implantation as initial palliative treatment. Demographic, clinical, and anatomical data were collected before the intervention. Mortality, intra- and post-procedural complications, need for re-intervention, intensive care requirements, and hospital stay were recorded. The characteristics at the time of definitive surgery are described. Discrete variables are presented as percentages, and continuous variables are presented with their medians and respective interquartile ranges. Twenty patients who underwent this treatment were reviewed, revealing a success rate of 80%. Complications due to stent dysfunction required surgical resolution. 95% of patients were dischargedfrom the institution after the procedure, and 17 patients reached a second definitive surgical stage. Three patients died afterthe procedure, but with no direct relation to it. Indications for ductal angioplasty with stent as an alternative treatment to systemic-pulmonary anastomosis by surgery are not yet fully defined; the strategy represents a valid alternative in appropriately selected patients. The presented experience shows results similar to international reference centers.

Surgical cystogastrostomy: Is it still worthwhile?

The article by Ker et al explores the treatment of peripancreatic fluid collection (PFC). The use of percutaneous drainage, endoscopy, and surgery for managing PFC are discussed. Percutaneous drainage is noted for its low risk profile, while endoscopic cystogastrostomy is more effective due to the wider orifice of the metallic stent. Surgical cystogastrostomy is a definitive treatment with a reduced need for reintervention, especially for cases with extensive collections and significant necrosis. The choice of treatment modality should be tailored to individual patient characteristics and disease factors, considering the expertise available.

Abstract 3008: Aortic Arch Endovascular Stent Grafts With Zone 0 Proximal Landing Zones For Geometrically Complex Aortas

Objectives: Fluctuation in total curvature (δK) significantly outperforms all other available measurements of shape in predicting clinical outcomes after thoracic endovascular aortic repair (TEVAR). We aim to identify if the Nexus® Aortic Arch Stent Graft System is a suitable and safe treatment modality for aortas with high δK. Methods: Twenty-five patients that underwent transcatheter aortic arch repair using the Nexus stent graft were included. 3D aortic models were segmented from the CTA image data using Simpleware ScanIP. The aorta segmentations were then smoothed and the outer surface isolated. A triangular mesh from the outer surface was generated in Python, and the mesh was divided into a number of partitions. δK was calculated by the sum of per partition total curvatures and the fluctuation in total curvature across the entire manifold surface. Failed TEVAR was defined by a) any device-related mortality or b) unplanned or device-related secondary surgical intervention 30 days from index TEVAR. This data was plotted into a pre-defined (δK,L –1 )-feature space with pre-established machine learning-derived boundary conditions. Results: Within a (δK,L –1 )-feature space defined by patients with aortic stent grafts with zone 2 or 3 proximal landing zones, our group used predictive modeling to classify patients into three zones (normal, successful TEVAR, and unsuccessful TEVAR) with 92.8% mean accuracy. Within this pre-defined boundary zone of unsuccessful TEVAR, 72.2% (13/18) of patients with the Nexus stent graft with zone 0 proximal landing zone underwent a successful TEVAR without need for re-intervention. Conclusions: Transcatheter aortic arch repair with a single branch, two-stent graft system with a zone 0 proximal landing zone can offer patients with a high degree of aortic shape fluctuation a greater chance at successful TEVAR than traditional aortic stent grafts with zone 2 or 3 landing zones.

Natural history of renal angiomyolipoma in a high-volume center: our experience during more than 15years of follow up.

To describe the natural history of AML, the clinical results and the need for treatment during long-term follow-up of renal AML. Retrospective study of patients diagnosed with AML by computed tomography or nuclear magnetic resonance between 2001 and 2019, with at least two follow-up images. Clinical and imaging variables, need for intervention, complications and follow-up time were recorded. Statistical analysis was performed using SPSS 22.0. 111 patients and 145 AML were included. The median follow-up was 6.17years (range 0.7-18.1, IQR 11.8-12.2). The median tumor size at diagnosis was 13mm (IQR 7.5-30), with 24 (16.4%) being ≥ 4cm. Most presented as an incidental finding (85.5%); in 3 (2.1%) cases, the presentation was as a spontaneous retroperitoneal hematoma. The main indication for intervention was size ≥ 4cm in 50%. Eighteen (12%) patients received a first intervention, being urgent in 3. Embolization was performed in 15 cases and partial nephrectomy in 3. The need for reintervention was recorded in five: two underwent partial nephrectomy and two total nephrectomy; one patient required a new urgent embolization. Of the non-operated patients, 43% decreased in size or did not change, while 57% increased, with the median annual growth being 0.13mm (IQR -0.11 to 0.73). There were no differences in the median growth in tumors measuring ≥ 4cm (0.16mm) at diagnosis vs. < 4cm (0.13mm) (p = 0.9). The findings of this study suggest that AML typically demonstrate a slow-progressing clinical course during long-term follow-up. Moreover, our observations, which cast doubt on tumor size as a reliable predictor of adverse clinical outcomes, advocate for a less intensive monitoring strategy in both monitoring frequency and choice of imaging modality.

The frozen elephant trunk: seeking a more definitive treatment for acute type A aortic dissection.

Conventional treatment for type A aortic dissection includes replacement of the ascending aorta with an open distal anastomosis in the hemiarch position. The frozen elephant trunk (FET) is a hybrid technique that extends the repair to the descending thoracic aorta. The goal is to improve resolution of malperfusion syndrome and to induce positive aortic remodelling and reduce the need for reintervention on the downstream aorta. We aim to summarize the data on the short and long-term outcomes of this technique. A thorough search of the literature was conducted isolating all articles dealing with aortic remodelling after the use of FET in case of type A acute aortic dissection. Keywords 'aortic dissection', 'frozen elephant trunk', 'aortic remodelling' and 'false lumen thrombosis' were used. Data for type B and chronic aortic dissections were excluded. FET use favourably influences aortic remodelling. The main advantages lie in the exclusion of distal entry tears in either the aortic arch or descending aorta thus restoring antegrade blood flow in the true lumen and inducing false lumen thrombosis. False lumen thrombosis is not only induced at the level of the stent deployment but also lower in the distal descending aorta. Moreover, it offers an adequate landing zone in the mid-descending aorta for second-stage endovascular or open surgical aortic repair, if needed. FET can be advantageous in the treatment of acute type A aortic dissection dealing with extended aortic pathology.

Retrospective Analysis of Bicanalicular Lacrimal Silicone Tube Intubation in Patients with Congenital Nasolacrimal Duct Obstruction: A Long-term Follow-up Study.

Congenital nasolacrimal duct obstruction (CNLDO) is the most common cause of epiphora in the first year of life. In addition to conservative therapy, there are several invasive methods available. The aim of this retrospective study was to conduct a long-term follow-up of bicanalicular lacrimal duct intubation as the primary intervention in a large cohort of patients with CNLDO. The electronic medical records of 487 patients with CNLDO who underwent bicanalicular tube intubation were reviewed. To determine the long-term outcomes, a telephone interview was conducted. A total of 328 eyes of 235 patients were included in the study. The median average follow-up period was 6.67 (5.58 - 8.67) years. At the time of the survey, 218 patients (92.8%) were symptom free. Mean patient satisfaction with surgical outcome was 10/10. To our knowledge, this study provides the longest follow-up of the largest patient cohort in the literature consisting of patients who underwent probing with bicanalicular lacrimal silicone tube intubation as a primary intervention for CNLDO. This study showed a high long-term postoperative success rate, with high postoperative satisfaction, few complications, and a low need for reintervention.

Cement augmentation for proximal humerus fractures: a meta-analysis of randomized trials and observational studies.

It is unclear if elderly patients treated with plate osteosynthesis for proximal humerus fractures benefit from cement augmentation. This meta-analysis aims to compare cement augmentation to no augmentation regarding healing, complications, and functional results. PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched for randomized clinical trials and observational studies. Effect estimates were pooled across studies using random effects models. The primary outcome is overall complication rate. Stratified analyses were performed for types of complication (implant-related or systemic). Secondary outcomes include re-interventions, hospital stay, operation time, functional scores, and general quality of life. Five observational studies and one randomized controlled trial with a total of 541 patients were included. The overall complication rate was significantly lower in the augmented group (15.6% versus 25.4%, OR 0.54 (95%CI 0.33-0.87)). This was caused by a reduction of implant-related complications (10.4% vs. 19.9%, OR 0.49 (95%CI 0.28, 0.88)). No difference in humeral head necrosis was found. Data on re-intervention, hospital stay, and operation time was limited but did not show significant differences. No impact on functional scores and general quality of life was detected. This meta-analysis shows that cement augmentation may reduce overall complications, mainly by preventing implant-related complications. No difference was detected regarding need for re-intervention, functional scores, general quality of life, and hospital stay. This is the first meta-analysis on this topic. It remains to be seen whether conclusions will hold when more and better-quality data becomes available.

Outcomes of COMBO therapy for severe mitral regurgitation compared with transcatheter edge-to-edge repair.

There are different types of transcatheter mitral valve repair (TMVr) currently in clinical use, including leaflet approximation, annular cinching, and restoration of the chordal apparatus of the mitral valve (MV). While the concomitant combination (COMBO) therapy of mitral transcatheter edge-to-edge repair (M-TEER) with another TMVr concept has been proven feasible, potentially offering patient-tailored treatment for severe mitral regurgitation (MR), a comparison with M-TEER alone has not been made. To evaluate the procedural and clinical outcome of COMBO therapies compared with M-TEER alone. We included consecutive patients undergoing COMBO and M-TEER between March 2015 and April 2018 at our Heart Valve Center, while excluding patients presenting a case of redo or with previous MV surgery. Procedural outcomes and all-cause mortality were compared between COMBO therapy vs. M-TEER alone. A total of 357 patients (mean age 78.9 ± 7.0 years, 53.2% male, M-TEER n = 322, COMBO n = 35; COMBO: MitraClip and the Carillon mitral contour system n = 26, MitraClip and Cardioband n = 5, and MitraClip and NeoChord n = 4) were analyzed. Patients with COMBO therapy had larger left chamber sizes, a lower left ventricular systolic ejection fraction (LVEF; COMBO: 37.4 ± 13.8%, M-TEER: 47.9 ± 14.3%, p < 0.001), and a more severe MR grade (p < 0.001). There were no significant differences in the prevalence of residual MR ≧2+. However, the need for re-intervention, always employing M-TEER, was more common in the COMBO group. During a mean 3.6-year long-term follow-up, there was no significant difference of all-cause mortality between both groups (Log rank p = 0.921). COMBO therapy may still be a beneficial therapy option for patients with severe MR who already have a more dilated left ventricle (LV), a more severe MR, and a more pronounced LV systolic dysfunction. The higher need for re-intervention in the COMBO group may signal more complex anatomies and possibly underlines the necessity of treating significant MR earlier. Future research is required to establish the COMBO approach as a toolbox-like treatment option, thus offering a patient-tailored approach depending on the individual anatomy and pathology.

A Multidisciplinary Minimally Invasive Approach Is Necessary for the Contemporary Management of Esophageal Diverticula.

Background: Esophageal diverticula were traditionally treated with open surgery, which is associated with significant morbidity and mortality rates. Management has shifted to minimally invasive approaches with several advantages. We examine outcomes in patients with esophageal diverticula treated with minimally invasive techniques by a multidisciplinary surgical team at a single center. Materials and Methods: A retrospective review of a prospectively maintained database was performed for patients who underwent minimally invasive surgery for esophageal diverticula at our institution from June 2010 to December 2022. Primary outcomes were 30-day morbidity and mortality rates. Secondary outcomes were symptom resolution, length of stay (LOS), readmission, and need for reintervention. Results: A total of 28 patients were identified. Twelve patients had pharyngeal diverticula, 7 patients had midesophageal diverticula, and 9 patients had epiphrenic diverticula. Thirty-day morbidity and readmission rates were 10.7% (3 patients), 1 pharyngeal (sepsis), 1 midesophageal (refractory nausea), and 1 epiphrenic (poor oral intake). There were no esophageal leaks. Average LOS was 2.3 days, with the pharyngeal group experiencing a significantly shorter LOS (1.3 days versus 3.4 days for midesophageal, P < .01 versus 2.8 days for epiphrenic, P < .05). Symptom resolution after initial operation was 78.6%. Reintervention rate was 17.9%, and symptom resolution after reintervention was 100%. There were no mortalities. Conclusion: This study demonstrates that esophageal diverticula can be repaired safely and efficiently when performed by a multidisciplinary team utilizing advanced minimally invasive endoscopic and robotic surgical techniques. We advocate for the management of this rare condition at a high-volume center with extensive experience in foregut surgery.

Thoracic aortic aneurysms, a single center's 10-years experience and analysis of outcomes.

Thoracic aortic aneurysms (TAAs) are an increasingly prevalent pathology with significant associated morbidity and mortality. Thoracic endovascular aortic repair (TEVAR) is the primary line of treatment. The purpose of this study was to analyse a single center's experience in the treatment of TAAs and identify possible risk factors for worse outcomes. A retrospective review of our institutional database was done to identify all patients treated for TAAs in a 10-year period, from 1 January 2012 to 31 December 2022. Data were extracted from patients' medical records. Primary outcome was all-cause mortality and secondary outcomes were procedure related morbidity (vascular access complications, medullary ischaemia, stroke, endoleaks, migration, aneurysm sac enlargement >5mm) and need for reintervention at 1-, 6- and 12-month follow-up. A descriptive and inferential analysis of the data was performed. Statistical analyses were conducted using the IBM Statistical Package for Social Sciences (SPSS) software. We identified 34 patients treated for TAAs in this period. Mean age was 68years [47-87] and 79.4% of patients were male. Mean aneurysm diameter was 63mm [35-100], 55.9% fusiform and 44.1% saccular. The majority (91.2%) were located at the descending thoracic aorta and 3 (8.8%) of them extended to the aortic arch. The most common aetiology was degenerative in 22 patients (64.7%), followed by aortic dissection in 8 patients (23.5%). Elective surgery was performed in 19 (61.3%) patients and 12 (38.7%) had urgent repair. TEVAR was the treatment of choice in 24 (77.4%) patients, and the remaining 7 (22.6%) were treated with hybrid surgery. Mean length of hospital stay was 10days [2-80] (6 days for elective repair versus 16days for urgent repair, p = .016). Follow-up period ranged from 1month to 10years. At 1 year follow-up, all-cause mortality was 15%, morbidity was 30% (with 6 (22%) patients having a type Ia endoleak) and need for reintervention was 22%. Aneurysm diameter was a significant risk factor for procedure related morbidity (median diameter of 73.5mm versus 56.0mm in patients with no morbidity; p = .027). The presence of type Ia endoleak was significantly associated with higher reintervention rates (p = .001), but not with higher mortality rates (p = .515). Age, female sex, aetiology and urgent repair weren't associated with any significant differences in the outcomes. TEVAR proved to be effective in the treatment of TAAs, with good outcomes at short and mid-term follow-up. TAAs should be diagnosed earlier and be promptly treated when meeting criteria to prevent worse outcomes.

Routine Use of Neck Drains Following Thyroid Operations to Prevent Complications Is No Longer Advisable.

The use of cervical drains to prevent cervical hematoma or seroma after thyroidectomy remains a controversial issue. Identify clinical and surgical risk factors for hematoma or seroma and evaluate the usefulness of routine use of drains following thyroid surgery. The authors conducted a retrospective multicentric study related to consecutive patients submitted to thyroid surgery in seven Portuguese hospitals between January 2018 and December 2020 (n=945). The data collected included the following parameters: age and gender of the patients, anticoagulation or anti-aggregating therapy, histological diagnoses, type of surgery, the presence or absence of postoperative drains, thyroid weight, length of hospital stay, postoperative complications, and reinterventions. In this study, surgical complications evaluated were limited to the presence of hematoma or seroma. A total of 945 patients who underwent thyroid surgery were included in the study. Twenty-seven patients (2.9%, n=27) experienced complications classified as hematomas or seromas. In the series, significant differences were observed between the two groups according to hypocoagulation or anti-aggregation status (OR=3.62; 95% CI 1.14-11.4) (p=0.001) and the nature of histological diagnosis (toxic vs. non-toxic benign disease) (OR=6.59; 95% CI 1.83-23.7). Hypocoagulation or anti-aggregation status were independently associated with a higher risk of complications. The presence of drains was associated with longer hospitalization periods (p<0.001) and not a decreased need for reintervention. Cervical hematoma or seroma are rare complications associated with both hypocoagulation and anti-aggregation therapy and with the presence of benign toxic pathology. The use of drains does not decrease the need for reintervention and is even associated with a longer length of hospital stay; therefore, their routine use should not be advised.

Early and Long-Term Clinical Outcomes of Ductal Stenting Versus Surgical Aortopulmonary Shunt Among Young Infants with Duct-Dependent Pulmonary Circulation.

Surgical aortopulmonary shunting (SAPS) and ductal stenting (DS) are the main palliations in infants with cyanotic congenital heart diseases (CHD). We aimed to study the safety and efficacy of DS and to compare it with SAPS as a palliative procedure in infants with CHD and duct-dependent pulmonary circulation. Retrospective institutional clinical data review of consecutive infants aged < 3months who underwent DS or SAPS over 5years. The primary outcome was procedural success which was defined as event-free survival (mortality, need for re-intervention, procedural failure) at 30days post-procedure. The secondary outcome was defined by a composite of death, major adverse cardiovascular events, or need for re-intervention at 6months and on long-term follow-up. We included 102 infants (DS, n = 53 and SAPS, n = 49). The median age at DS and SAPS was 4days (IQR 2.0-8.5) and 8days (IQR 4.0-39.0), respectively. The median weight at intervention was 3.0kg (IQR 3.0-3.0) and 3.0kg (IQR 2.5-3.0) in the two respective arms. Tetralogy of Fallot with pulmonary atresia was the most common indication for DS and SAPS. The 30-day mortality was significantly higher in SAPS group as compared with DS group (p < 0.05). However, 30-day major adverse cardiac events (MACE) rates were similar in both groups (p = 0.29). DS was associated with shorter duration of mechanical ventilation, duration of stay in the intensive care and hospital stay than with SAPS. At 6months, there was no significant difference in terms of mortality or event-free survival. Long-term MACE-free survival was also comparable (p = 0.13). DS is an effective and safer alternative to SAPS in infants with duct-dependent pulmonary circulation, offering reduced procedure-related mortality and morbidity than SAPS. Careful study of ductal anatomy is crucial to procedural success. However, long-term outcomes are similar in both procedures.

Examining the Outcomes of Hybrid Coronary Revascularization in Acute STEMI Patients from 2015 to 2022.

The global rise of chronic diseases, especially cardiovascular disease (CVD), poses a significant public health challenge, being a leading cause of death and disability worldwide. In Iran, the surge in CVD incidence and its risk factors, along with a decrease in the age of onset, has notably increased the reliance on coronary artery bypass grafting (CABG) as a life-saving intervention. Staged hybrid coronary revascularization (HCR), which combines percutaneous coronary intervention with delayed CABG, offers a novel approach for patients with complex coronary artery disease, potentially improving survival and reducing complications. Considering the newness of this treatment method and the limitations of previous studies, we investigated the results of staged HCR in acute ST-elevation myocardial infarction (STEMI) patients in this study. This observational study was performed on consecutive patients with acute STEMI who underwent staged HCR and were referred to Valiasr and Razi hospitals in Birjand from 2015 to 2022. The required information (demographic information, angiography result, and operation side effects) was collected in a checklist. If necessary, the patients were contacted by phone. After collecting the data, they were entered into SPSS version 16 software. This study was conducted on 33 patients with a mean age of 64.88 ± 9.24 years (69.7% male). The average hospital stay was 11.6 ± 8.9 days (3 to 72 days). The mean ejection fraction and syntax score were 36.5% ± 10.2% and 31.21 ± 6.7, respectively. Following surgery and during hospitalization, arrhythmias were observed, including 33.3% with premature ventricular contractions, 18.1% with atrial fibrillation, and 3.1% with ventricular tachycardia. The average number of pack cells (red blood cells that have been separated for blood transfusion) and creatinine changes before and after hybrid surgery were 640.9 ± 670.9 cc and 0.055 ± 0.07. In the follow-up, 9.09% of patients had late mortality, 6.1% of patients had urinary tract infections during hospitalization, 6.1% of patients had surgical site infections, 3.1% needed dialysis, and none of the studied patients had premature death or need for reintervention. The results of our study indicated that staged HCR performed early after an ACS is not associated with significant mortality or complications. Therefore, it is advisable to consider staged HCR as a surgical option in appropriate cases.

(177) Androgen Deprivation Therapy Does Not Increase Rates for Reintervention, Complication, or Infection in Penile Implant or Artificial Urinary Sphincter Surgery

Abstract Introduction Prostate cancer treatment carries significant quality of life implications, namely erectile dysfunction and stress urinary incontinence. Treatment options include genitourinary implants such as inflatable penile prosthesis (IPP) or artificial urinary sphincter (AUS). Given the association with androgens and penile and urethral health, there may be concern patients on androgen deprivation therapy (ADT) could have worse outcomes following IPP and AUS. Objective To evaluate whether patients on ADT undergoing IPP and AUS surgery are at increased risk for reintervention, complication, and infection. Methods We queried TriNetX, a collaborative research enterprise, for all adult male patients undergoing AUS or IPP. Cohorts were defined by those taking ADT 3 months before or anytime after surgery and those not taking ADT. ADT medications included: leuprolide, bicalutamide, flutamide, nilutamide, apalutamde, and darolide. We performed sub-analysis for leuprolide and bicalutamide, the two most prescribed ADT medications. Cohorts and outcomes were defined using Current Procedural Terminology (CPT) and International Classification of Diseases (ICD-10) codes. We used the impact of age, prostate cancer, history of prostatectomy and history of radiation to generate propensity score matching (PSM). Our primary outcome was need for reintervention (revision, removal, or replacement surgery based on CPT codes). Secondary outcomes included infection rate and complication rate based on ICD-10 codes. Analytics were performed via TriNetX on demographic data which calculated Risk Ratios and were run July 2023. Results There were 12,143 patients who received an IPP and 5487 who received an AUS (Table 1), with. 401 and 635 patients on ADT, respectively. Patients on ADT had similar rates of reintervention (9.4% vs 12.9%, RR = 0.72, p = 0.11), complication (17.7% vs 22.8%, RR =0.78, p=0.08), and infection (4.1% vs 4.8%, RR =0.84, p=0.60) for IPP. For bicalutamide, patients had lower complication rates (11.3% vs 18.2%, RR = 0.62, p=0.04) and similar reintervention rates (5.2% vs 9.9%, RR = 0.52, p=0.07). There were less than 10 instances of infection and thus TriNetX rounded these numbers to 10 (denoted by *) as part of a patient safety mechanism. Rates were similar for patients on leuprolide (reintervention: 9.8% vs 8.9%, RR =1.1, p = 0.69, complication: 17.5% vs 17.8%, RR = 0.98, p=0.92, infection: 4.0% vs 4.9%, RR = 0.81, p=0.57). Patients receiving an AUS showed similar rates for reintervention (20.8% vs 24.0% RR =0.87, p=0.17), complications (26.1% vs 25.6%, RR=1.0, p=0.85), and infections (2.3% vs 3.7%, RR=0.61, p=0.13) regardless of ADT. This held true for subanalyses for bicalutamide (reintervention: 22.7% vs 22.3%, RR =1.0, p = 0.92, complication: 27.7% vs 24.6%, RR = 1.1, p=0.43, infection: 3.8%* vs 3.8%*, RR = 1, p=1)., and leuprolide (reintervention: 19.8% vs 23.3%, RR =0.85, p = 0.18, complication: 25.3% vs 28.7%, RR = 0.8, p=0.21, infection: 1.9%* vs 3.2%, RR = 0.59, p=0.17). Conclusions Patients with IPP or AUS seemingly do no worse on ADT and in some comparisons even seemed to fare better. Further evaluation into the duration of ADT may provide clinical context, but based on these results, ADT should not limit implant surgery.
