Anterior Glenohumeral Instability

➢ Anterior glenohumeral instability is a complex orthopaedic problem that requires a detailed history, a thorough physical examination, and a meticulous review of advanced imaging in order to make individualized treatment decisions and optimize patient outcomes.➢ Nonoperative management of primary instability events can be considered in low-demand patients, including elderly individuals or younger, recreational athletes not participating in high-risk activities, and select in-season athletes. Recurrence can result in increased severity of soft-tissue and osseous damage, further increasing the complexity of subsequent surgical management.➢ Surgical stabilization following primary anterior instability is recommended in young athletes who have additional risk factors for failure, including participation in high-risk sports, hyperlaxity, and presence of bipolar bone loss, defined as the presence of both glenoid (anteroinferior glenoid) and humeral head (Hill-Sachs deformity) bone loss.➢ Several surgical treatment options exist, including arthroscopic Bankart repair with or without additional procedures such as remplissage, open Bankart repair, and osseous restoration procedures, including the Latarjet procedure.➢ Favorable results can be expected following arthroscopic Bankart repair with minimal (<13.5%) bone loss and on-track Hill-Sachs lesions following a primary instability event. However, adjunct procedures such as remplissage should be performed for off-track lesions and should be considered in the setting of subcritical glenoid bone loss, select high-risk patients, and near-track lesions.➢ Bone-grafting of anterior glenoid defects, including autograft and allograft options, should be considered in cases with >20% glenoid bone loss.

Advanced Adhesive Approach to Support a Minimally Invasive Full Mouth Rehabilitation.

Patients who exhibit severe loss of tooth structure are challenging to rehabilitate. Conventional treatment of these patients may require adjunctive procedures of surgical crown lengthening, elective endodontic therapy and placement of posts and cores to retain full coverage crowns as part of a full mouth rehabilitation. Minimally invasive approaches to treatment of these patients provides opportunity to conserve tooth structure and to reduce adjunctive procedures by using an advanced adhesive approach to retain all ceramic partial coverage restorations as part of a full mouth rehabilitation. The use of an advanced adhesive approach to perform a full mouth reconstruction restoring occlusal vertical dimension (OVD) is described. This approach emphasizes preserving healthy tooth structure, maximizing restoration adhesion to enamel and dentin, maintaining pulpal vitality and minimizing adjunctive dental procedures. The preparation design focuses on being defect-oriented to remove only diseased or undermined tooth structure. The all ceramic restorations are additive, where indicated, to further aid in preserving tooth structure. An advanced adhesive approach using an immediate dentin seal and resin coating over exposed dentin and composite resin cement under rubber dam isolation is used to lute the restorations. The restorations are fabricated using micro-layered lithium disilicate ceramic to maximize the esthetic appearance of the rehabilitation where needed. An advanced adhesive approach to full mouth rehabilitation should be considered as a treatment option for patients exhibiting tooth surface loss as an alternative to conventional full coverage restorations when clinical parameters allow.

Tarsal Coalition Resection in Children: Is it Effective?

Tarsal coalitions in children are a group of disorders that typically present as a rigid flatfoot deformity. Operative treatment generally consists of resecting the coalition alone or resection plus flatfoot reconstructive procedures. The purpose of this study was to evaluate the rate and risk factors for complications, including infection, recurrence, and reoperation, following the surgical management of tarsal coalitions in children. This is a retrospective cohort study on the surgical outcomes of pediatric tarsal coalitions alone or in combination with adjunctive procedures. This study was conducted between 01/01/2008 and 12/31/2019 and utilized electronic health records and chart review was performed to describe patient demographic, clinical, perioperative characteristics, and whether patients have subsequent foot and ankle procedures after the index resection surgery. The study cohort included 165 feet belonging to 144 patients. The age range at time of surgery was 12 years of age (11-14). Of the 165 feet, 18 (10.9%) experienced a postoperative complication, including six infections of which two required reoperation, six recurrences all requiring reoperation, and six reoperations not due to recurrence. Patients with a postoperative complication demonstrated increased age (13.9 years vs 12.4 years, p=0.007), obesity (33.3% vs 13.6%, p=0.026), and/ or preoperative hindfoot valgus deformity (33.3% vs 7.5%, p=0.004). The overall postoperative complication rate was 10.9%. Results of this study provided important information for providers as they discuss different treatment approaches and anticipated outcomes with patients and their families.

Impact of 2023 Ventral Hernia Repair CPT Code Changes on Work Relative Value Units in a Tertiary Hernia Referral Center.

CPT codes for ventral hernia repair (VHR) changed in January 2023 to address the heterogeneity of procedures with a concomitant shift from a 90-day to a 0-day global period. This study reviews a tertiary referral center's experience with hernia coding comparing the work relative value units (wRVUs) generated for ventral hernia repair pre-2023 compared to post-2023. CPT codes were analyzed for patients undergoing open or laparoscopic VHR before updates to the CPT hernia codes (January 2022-September 2022) and following CPT change (January 2023-September 2023). Work RVU values were assigned based on nationally published values. CPT codes in 2022, CPT codes in 2023, 8 inpatient E&M codes, and 5 outpatient E&M codes were evaluated. 299 patients underwent VHR, 143 in 2022 and 156 in 2023. Average procedural VHR wRVUs increased from 9.6 in 2022 to 11.6 in 2023 (p<0.001). Procedures involving myofascial advancement flaps/component separation techniques (53.8% vs. 48.7%, p = 0.419) and wRVUs for the component separation procedures were similar between 2022 and 2023, respectively 17.7 vs 16.1 (p=0.419)]. The wRVUs associated with adjunctive procedures (mesh removal/placement) decreased from 3.3 to 0.6 (p<0.001) in the post-2023 era. Postoperative E&M wRVUs increased in 2023 for postoperative inpatient (0.48) and postoperative outpatient (0.39) services, compared to 0 wRVUs in 2022. Overall, the total management including follow-up clinic visit adjusted wRVUs for hernia repair was similar between 2022 and 2023, respectively 30.7 vs 29.2 (p=0.409). Procedural wRVUs for anterior abdominal hernia repair increased from 2022 to 2023 (p<0.001) at a tertiary referral medical center. However, total wRVUs, including the operation and postoperative visits, remained unchanged.

Settings and Clinical Applications of Subthreshold Micropulse Laser Therapy: A Review.

Subthreshold lasers operate below the threshold of visible tissue damage, thereby preventing ophthalmoscopically visible thermal damage to the chorio-retinal layers. They could represent a safe and effective alternative and/or adjunctive procedure to conventional lasers in treating diabetic macula edema (DME), central serous chorioretinopathy (CSCR), and branch retina vein occlusion (BRVO). This review focuses on the use of subthreshold micropulse laser (SMPL), its settings, and clinical applications. Despite their widespread use, a standardized protocol for sub-threshold laser settings has not been established yet, and thus, there is uncertainty in selecting effective and safe parameters for any specific situation. We conducted a comprehensive overview of the existing indications for subthreshold laser therapy and their settings for different retinal diseases. The debate revolves around which parameters could guarantee the safety of the procedure for each case, depending on the duty cycle, the laser wavelength, the spot duration, and the power, with laser power titration on one side or choosing a fixed lowered power value on the other side. SMPL therapy for DME, CSCR, and BRVO-associated macular edema has shown significant effectiveness in reducing the macular thickness, facilitating subretinal fluid absorptions, increasing the best corrected visual acuity (BCVA) and reducing the number of intravitreal injections (IVI) required annually. We presented a broad list of the laser parameters reported in the literature, organized into different tables divided based on the specific pathology, with the aim of providing a useful tool for future studies.

Long-Term Outcomes in Patients Managed with the EndurantTM Endograft under Elective Setting.

Background/Objectives: Device selection during endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAAs) remains an important issue for ensuring endograft durability. This study evaluated the early and follow-up outcomes of elective EVAR with the Endurant platform. Methods: A single-center retrospective analysis was conducted including consecutive elective EVAR procedures with the Endurant II/IIs (2008 to 2024) device. Primary outcomes were technical success, mortality and major complications at 30 days. Survival, endoleak I/III and freedom from reintervention were secondary outcomes. Cox proportional hazards models were employed for risk-adjusted follow-up outcomes. Results: In total, 361 patients were included (72.7 ± 7 years; 96% males; mean AAA diameter 62 ± 14 mm); 92% received a bifurcated device, and 89% conformed to the instructions for use. Technical success was 99.7%. Intra-operative adjunctive procedures included 4.4% proximal cuffs and 1.7% endoanchors. The thirty-day mortality rate was 0.6%, and the major complication rate was 4.1%. Survival was 81% (SE 4.8%), 72% (SE 6.4%) and 52% (SE 9.2%) at 4, 6 and 8 years, with aneurysm-related mortality at 1.7%. Freedom from endoleak Ia was 76% (SE 7.3%) at 6 years, freedom from endoleak Ib was 79% (SE 7.4%) at 7 years and freedom from endoleak III was 94% (SE 3.7%) at 5 years. Freedom from reintervention was 71% (SE 6.1%) and 55% (SE 7.9%) at 5 and 7 years, respectively. No device-related co-factor affected long-term outcomes. Conclusions: Endurant II/IIs endograft is a safe and effective EVAR solution with excellent early outcomes and low long-term aneurysm-related mortality. The need for reintervention in the long term affected less than 50% of cases.

Abstract B015: Duodenal aspiration biopsy in diagnosis of pancreatic neoplasms

Abstract Introduction Intraductal papillary mucinous neoplasms (IPMNs) are a subset of lesions with elevated malignant potential, warranting their inclusion in screening standards. Despite endoscopic ultrasound (EUS) with fine-needle aspiration biopsy (FNAB) serving as the standard for verification, the occurrence of erroneous conclusions remains significant. Consequently, analysis of pancreatic juice is considered as a potential adjunctive diagnostic method. However, the absence of methods for obtaining pancreatic juice in adequate volume and quality poses a barrier to the widespread adoption of this approach.Materials and MethodsA method of duodenal aspiration biopsy (DAB) was developed involving active aspiration from the lumen of duodenum, yielding large volume of the mix of pancreatic juice and bile uncontaminated by gastric juice. Patients diagnosed with pancreatic neoplasms utilizing EUS with FNAB, were enrolled and ALB was implemented as an adjunctive diagnostic procedure. Cytological analysis of the material obtained was performed along with measuring the level of carcinoembryonic antigen (CEA). The level &amp;gt;192 ng/mL was considered significant, according to the Fukuoka 2017 guidelines.ResultsIn patients with cystic neoplasms of the pancreas undergoing DAB, results of cytological examination were non-informative in certain cases. However, analysis of CEA levels in the pancreatic juice and bile mixture always demonstrated strong concordance with the degree of dysplasia. In some instances, elevated CEA values facilitated the adoption of a more aggressive treatment strategy, leading to the detection of carcinoma. Conversely, low CEA levels prompted the decision to opt for observation rather than radical surgery in other cases.ConclusionDiagnosing precancerous transformations of the pancreas remains a challenging task, characterized by a notable rate of false-positive or false-negative conclusions. The DAB method offers a promising solution, seamlessly integrating into routine clinical practice and offering supplementary data to enhance the verification of pancreatic cancer.

"Veins first" versus "artery first" approach for management of mixed arterial venous leg ulcers (MAVLU): Systematic review and meta-analysis.

Mixed Arterial and Venous Leg Ulcers (MAVLU) are challenging. The optimal intervention sequence (artery-first vs vein first) is unclear. This review evaluates current evidence on surgical intervention sequencing. MEDLINE, PUBMED, SCOPUS and EMBASE were searched using the term 'mixed arterial venous leg ulcers.' Studies were eligible if they reported ulcer healing outcomes in MAVLU patients. Pooled proportions were calculated by random effects modelling. The search yielded 606 studies, eight of which contained sufficient data to include in the analysis. There were no randomized controlled trials. Initial modified compression (MCT) and rescue revascularisation in MAVLU with ABI 0.5 to 0.85 achieved a pooled healing rate of 75% (95% CI 69% to 80%) compared to 79% (95% CI 61% to 93%) in patients with standard VLUs. The pooled rescue revascularisation rate for MAVLU patients with moderate arterial disease was 25% (95% CI 6% to 51%). Patients with severe arterial disease (ABI <0.5) who underwent arterial intervention first were less likely to heal (pooled proportion 40%; 95% confidence interval 16% to 66%). No studies compared either MCT or venous ablation with arterial revascularisation as first-line in patients with moderate arterial disease (ABI 0.5 to 0.85) alone or severe arterial disease (ABI <0.5) alone. There was marked heterogeneity between studies with respect to ulcer healing outcomes reported, definitions of ulcer healing, duration and size of ulcers at presentation, use of adjunct procedures such as skin grafting, unit of measurement (legs vs patients) and duration of follow up. A 'veins first' approach to MAVLU is plausible but robust data are lacking and should be evaluated in a randomized controlled trial.

BEST1 associated bestrophinopathies with angle closure and post-surgical malignant glaucoma

ABSTRACT Introduction Mutations in BEST1 gene have been linked to the development of refractory angle closure glaucoma (ACG). This study aims to delineate the clinical characteristics, genetic mutations, and disease progression in patients with autosomal recessive bestrophinopathy (ARB) and autosomal dominant Best vitelliform macular dystrophy (BVMD) who are presented with treatment-resistant ACG. Methods This retrospective analysis encompasses a comprehensive ophthalmic assessment, retinal imaging, and mutational profiling of six patients diagnosed with bestrophinopathy and concurrent ACG, with a particular emphasis on the risk of post-glaucoma filtration surgery malignant glaucoma (MG). Exome sequencing was conducted utilizing a next-generation sequencing (NGS) based gene panel. Results The cohort included five patients with ARB and one with BVMD, with a mean (±SD) age at ACG diagnosis of 35.1 ± 6.9 years. NGS analysis revealed homozygous BEST1 variants in four patients (ARB; cases 1–4) and a heterozygous BEST1 variant in one patient (BVMD; case 5). One patient (ARB; case 6), despite a recessive pedigree, showed a single heterozygous variant, suggesting the presence of an undetected heterozygous variant indicative of compound heterozygous autosomal recessive inheritance. A novel non-frameshift deletion (c.841_843delTTC; p.Phe281del) was identified in case 2. Surgical intervention was required due to uncontrolled glaucoma in all cases except case 4. All five cases that underwent glaucoma filtration surgery developed MG, which was effectively managed with combined iridozonulo-hyaloido-vitrectomy (IZHV) and pars plana vitrectomy (PPV). Cases 5 and 6, harboring a heterozygous pathogenic variant (c.241 G>A; p.Val81Met), experienced refractory MG and corneal decompensation necessitating multiple interventions. Conclusion Genomic analysis plays a pivotal role in the management of bestrophinopathies with ACG. Characterization of mutational types facilitates prognostication and enables timely interventions. IZHV with PPV emerges as a promising standalone or adjunctive procedure for the management of glaucoma among patients with BEST1 mutations and ACG.

Mechanical thrombectomy with the InThrill device for thrombosed hemodialysis access: A single center experience.

To assess the effectiveness and safety of the InThrill Thrombectomy System in treating thrombosed arteriovenous fistulas (AVFs) and grafts (AVGs) via mechanical thrombectomy. Institutional database was retrospectively searched to identify all thrombectomy procedures performed using the study device at our hospital for thrombosis of AVFs or AVGs. Inclusion criteria encompassed patients aged 18 and above who underwent AV access thrombectomy using the study device. Intraprocedural metrics, including procedure time, device time, blood loss, and adjunctive procedures were collected. Technical success was defined as restoration of flow combined with <30% residual diameter stenosis of the treated vascular segment. Clinical success was defined as the resumption of normal hemodialysis for a minimum of at least one session following intervention. Through 3-month follow-up, patency, and adverse events were evaluated. A total of 20 thrombectomies were performed on 2 AVFs and 18 AVGs in 13 patients. Median procedure and device times were 45 and 10 min, respectively. Balloon angioplasty was performed in all cases with additional stenting in 40% (8/20) of cases to address stenosis following thrombus removal. No other mechanical thrombectomy devices were utilized. Intraprocedural thrombolytics were not administered in any case. Average blood loss was 10 mL. The technical success and clinical success rates were 100% (20/20) and 95% (19/20), respectively. There were no intraoperative adverse events. One patient developed a post-operative minor hematoma, and one patient developed a post-operative pseudoaneurysm at the access site. The primary patency rate was 77% (10/13) at 1 month. Both assisted primary and secondary patency rates were 100% at 1 and 3 months. These preliminary results suggest that the InThrill Thrombectomy System is rapid, safe, and effective for thrombolytic-free treatment of AV access thrombosis in hemodialysis patients.

Modified Ex Vivo Renal Reconstruction to Facilitate Fenestrated-Branched Endovascular Repair of a Thoracoabdominal Aortic Aneurysm.

To report the use of modified ex vivo renal artery (RA) reconstruction in a patient with 2 small right RAs (RRAs) in anticipation of planned fenestrated-branched endovascular aortic repair (FB-EVAR) of thoracoabdominal aortic aneurysm (TAAA). A staged hybrid repair was utilized in a patient with Extent II TAAA involving celiac axis (CA), superior mesenteric artery (SMA), single left RA (LRA), and 2 small (<3 mm) RRAs. The first-stage operation consisted of hepato-renal bypass using modified ex vivo renal reconstruction with single end-to-end anastomosis to both RAs using a saphenous vein graft. A second stage FB-EVAR was performed using patient-specific manufactured stent-graft with 3 fenestrations for the CA, SMA, and LRA 6 weeks later. The patient recovered with no complications. At 4 years, the patient had widely patent hepato-renal bypass and target vessels with normal renal function. The use of adjunctive hybrid procedures may optimize or facilitate FB-EVAR. In this patient, salvage of 2 small RAs was not ideally suited for branch stenting but was possible using modified ex vivo RA reconstruction with preservation of kidney parenchyma and function. This case report illustrates a hybrid approach to overcome one of the most frequent limitations to total endovascular incorporation of renal arteries, eg small diameter, early bifurcation and multiple vessels. The modified ex vivo technique allows meticulous renal artery reconstruction without the deleterious effect of warm ischemia and without the cumbersome reconstruction of ureter and vein that is needed with traditional on table ex vivo auto transplantation. The technique is used in a minority of cases and adds the morbidity of open approach. Case selection is of paramount importance.

Effect of Preoperative Coronal Plane Alignment on Actual Versus Predicted Alignment Using Patient Specific Instrumentation in Total Ankle Replacement

Alignment in total ankle replacement is important for success and implant survival. Recently there has been the introduction and adoption of patient specific instrumentation for implantation in total ankle replacement. Current literature does not evaluate the effect of preoperative deformity on accuracy of patient specific instrumentation. A retrospective radiographic analysis was performed on 97 consecutive patients receiving total ankle replacement with patient specific instrumentation to assess the accuracy and reproducibility of the instrumentation. Subgroup analysis evaluated the effect of preoperative deformity. All surgeries were performed by fellowship trained foot and ankle surgeons without industry ties to the implants used. Preoperative and postoperative films were compared to plans based on computerized tomography scans to assess how closely the plan would be implemented in patients. Overall postoperative coronal plane alignment was within 2° of predicted in 87.6% (85 patients). Similarly, overall postoperative sagittal plane alignment was within 2° of predicted in 88.7% (86 patients). Tibial implant size was accurately predicted in 81.4% (79 patients), and talus implant size was correct in 75.3% (73 patients). Patients with preoperative varus deformity had a higher difference between predicted and actual postoperative alignment compared to valgus deformity (1.1° compared to 0.3°, p=0.02). A higher average procedure time was found in varus patients, and more adjunctive procedures were needed in patients with varus or valgus deformity, but these were not significant, p>0.5. Surgeons can expect a high degree of accuracy when using patient specific instrumentation overall, but less accurate in varus deformity.

A new technique of monsplasty as an adjunctive procedure in cases of abdominoplasty: A prospective clinical trial

BackgroundNo standard monsplasty technique has existed until now. Although various monsplasty methods have been described, they exhibit high complication rates with sparse postoperative data. Studies that used pubic suspension techniques did not describe exact anatomical landmarks for the mons pexy. This study aimed to improve the aesthetic and functional appearance of the pubic region with long-term results for all grades of pubic ptosis or bulging with abdominoplasty and provide exact anatomical points to anchor the mons to the rectus sheath. MethodsThis non-randomized prospective clinical trial included 30 patients with various degrees of abdominal wall laxity between December 2017 and September 2019. The surgical procedure was performed for female patients with pendulous abdomen, pubic ptosis or bulging, body mass index ≤35 ​kg/m2, and age 18–60 years. All patients were followed for up to one year; patient satisfaction was assessed before and after surgery regarding aesthetic results and impact on outfits, hygiene, and sexual activity. ResultsThe marginal homogeneity test revealed a statistically significant patient satisfaction rate regarding outfits, sexual function, hygiene, and aesthetics. Regarding postoperative complications, seroma (one case) was managed by aspiration, and one case of wound dehiscence was managed conservatively with dressings. ConclusionThis study recommends a quick and reproducible monsplasty technique with a low complication rate, a technique that helps determine specific anatomical landmarks for anchoring the mons to the rectus sheath. Combining this technique with abdominal contouring is advisable for optimal aesthetic results and maintained lymphatic drainage in the pubic region.

ACL Revision Using Quadriceps Tendon Autograft and Lateral Extra-Articular Tenodesis

Revision of anterior cruciate ligament (ACL) reconstruction presents numerous challenges not encountered in the primary setting and therefore requires thorough preoperative planning. Addressing tunnel widening is the primary concern, and therefore the appropriate graft choice is pivotal. Quadriceps tendon autograft recently has gained popularity for its dimensions and the possibility to harvest a bone block from the patella that can fill potential tunnel bone defects. Adjunctive procedures to isolated ACL reconstruction such as lateral extra-articular tenodesis (LET) may help in sharing the loads with the neoligament, with recent findings recommending LET in the revision setting. The technique presented in this Technical Note describes a 1-stage revision ACL combined with LET using a quadriceps tendon autograft with a bone plug.

The Statistical Fragility of Lateral Extra-articular Tenodesis Research: A Systematic Review.

A P value of <.05 is often used to denote statistical significance; however, in many scenarios, this threshold is vulnerable to a small number of outcome reversals. This study joins a body of studies within the orthopaedic literature that evaluate the statistical fragility of existing research via metrics such as fragility index (FI) and fragility quotient (FQ). The purpose of this study was to investigate the statistical fragility of randomized controlled trials (RCTs) and comparative studies on the topic, given the resurgent interest in lateral extra-articular tenodesis (LET) to augment primary or revision anterior cruciate ligament reconstruction (ACLR). It was hypothesized that the outcomes reported in these studies would be statistically fragile. Systematic review; Level of evidence, 4. Comparative studies and RCTs regarding LET as an adjunct procedure to ACLR published between 2000 and 2022 were analyzed. Descriptive characteristics, dichotomous outcomes, and continuous outcomes were extracted. The FI and continuous FI (CFI) were calculated by the number of event reversals to change significance; the FQ and continuous FQ (CFQ) were calculated to normalize the fragility metrics per sample size. Of 455 studies screened, 29 studies were included (9 RCTs, 20 comparative); 79.3% of included studies were published after 2020. A total of 48 dichotomous and 265 continuous outcomes were analyzed. The median FI was 9.0 (IQR, 7.0-13.3), with FQ of 0.1 (IQR, 0.04-0.17); the median CFI was 7.8 (IQR, 4.2-19.6), with CFQ of 0.12 (IQR, 0.08-0.19). The FQ and CFQ for studies on LET with revision ACLR were larger (0.117 and 0.113, respectively) than those focused on primary ACLR (0.042 and 0.095, respectively). Studies focused on LET with primary ACLR were more fragile than those on LET with revision, which suggests that further research on the indications for LET with primary ACLR is necessary. Future orthopaedic comparative research should include fragility metrics alongside traditional P values.

Selective complex fractionated atrial electrogram ablation based on the number-of-fractionation for persistent atrial fibrillation refractory to pulmonary vein isolation.

Previous studies have suggested that the prolonged or highly fractionated electrograms during atrial fibrillation (AF) are closely related to the reentrant driver regions. We hypothesized that exploration and ablation of these critical complex atrial fractionated electrograms (CFAE) may improve the outcome of persistent AF (PeAF) refractory to conventional PVI. A total of 73 PeAF patients with residual inducibility or failed cardioversions of AF after PVI were enrolled and underwent number-of-fractionation mapping (NFM) by counting the number of fractionations in 2.5s at each of the points using the CARTO3 (ICL mode) and EnSite (fractionation map) systems. After NFM, selective CFAE ablation (NFM-CA) targeting the sites of the upper 40% of the counted fraction number (NF40) was performed as an additional procedure for refractory PeAF. We investigated the prognosis of these patients within 24months after the index ablation procedure and the relationship between changes in activation patterns during the ablation procedure and their prognosis. We also performed a propensity score-matched analysis comparing these patients with historical controls (HC) to identify the optimal indications for NFM-CA. The AF/AT free survival rate was 79.1% at 12months and 56.7% at 24months. Patients with AF termination or AF cycle length prolongation > 21ms during the procedure had significantly better AF/AT-free survival rates than those without notable activation changes (87.7% vs. 69.0%, logrank p = 0.028). After propensity-matched analysis, AF/AT-free survival showed comparable results between the two groups (1year; NFM 72.1% vs. HC 77.1%, logrank p = 0.649). NFM-CA is a versatile and less invasive adjunctive procedure for patients with PVI-refractory PeAF who showed a comparable prognosis to patients with PVI-compliant PeAF. In particular, remarkable activation changes during the procedure (AFCL prolongation > 21ms or acute termination) suggest a favorable prognosis.

Standard Total Ankle Arthroplasty vs. Patient-Specific Instrumentation: A Comparative Study.

This retrospective study aims to compare surgical outcomes between two cohorts of patients who underwent total ankle arthroplasty (TAA) using either standard technique or patient-specific instrumentation (PSI). A consecutive series of patients who affected of end-staged ankle osteoarthritis were retrospectively assessed and divided into two groups based on TAA techniques: a TAA standard technique group and a TAA-using PSI group. The two groups were compared in terms of operative time, additional procedures, complications (neurovascular and wound problems, infection, loosening and osteolysis, revision and explantation rates, and perioperative fracture), clinical scores, and range of motion (ROM). Fifty-one patients underwent standard TAA, while 13 patients underwent TAA with PSI. At 1-year follow-up, there were no significant differences in complication rates between the two groups (p > 0.05). AOFAS scores were similar, with the standard TAA group scoring 83.33 ± 7.55 and the PSI group scoring 82.92 ± 9.7 (p = 0.870). Likewise, the postoperative ROM did not differ significantly, with 15.12 ± 7.6 degrees for the standard TAA group and 16.05 ± 6.7 degrees for the PSI group (p = 0.689). However, the standard TAA group experienced significantly longer operative time (107.1 ± 22.1 min) compared to the PSI group (91.92 ± 22.9 min, p = 0.032). Additionally, the standard TAA group required more adjunctive procedures (29.7%) compared to the PSI group (7.7%, p = 0.04). Residual pain was also more frequently reported in the standard TAA group (62.7%) than in the PSI group (30.7%, p = 0.038). While both techniques resulted in comparable complication rates, clinical scores and ROM, the PSI group reported significantly shorter operative time and less residual pain, thus requiring fewer postoperative procedures.

Single-center experience with the JETi Hydrodynamic Thrombectomy System for acute limb ischemia

ObjectiveAcute limb ischemia (ALI) remains a vascular emergency with high morbidity and mortality. While the JETi Hydrodynamic Thrombectomy System (Abbott) offers a percutaneous approach to fragment and aspirate the thrombus in patients with arterial occlusions, data on its efficacy and safety are limited. This study reports our early experience using the JETi device to treat ALI at our institution. MethodsThis is a single-center, retrospective review of patients with ALI treated with the JETi device between September 2020 and December 2022. Patients were included if the JETi device was used either as a primary intervention or as an adjunct procedure. The primary endpoint was technical success defined as <50% residual thrombus after intervention. Secondary endpoints included achieving complete resolution of the thrombus on angiogram, acute kidney injury (AKI), major bleeding, 30-day major amputation, and 30-day mortality. ResultsA total of 59 JETi procedures for ALI (median age 62 years [interquartile range: 56-71 years]) were performed on 39 male and 20 female patients. The median time from onset of symptoms to hospitalization was 24 hours (interquartile range: 4-168 hours). Rutherford classifications were I (10), IIa (27), IIb (14), and undocumented (8). Etiology of ALI was native vessel thrombosis (27), embolism (16), graft/stent thrombosis (14), and iatrogenic (2). A total of 124 vessels were treated, with an average of 2.1 vessels per procedure. The primary outcome was achieved in 86% (107/124) of the arteries, with 82% (102/124) successfully opened using the JETi device alone without the need for any adjunctive therapy. Complete resolution of the thrombus using JETi was achieved in 81% (101/124) arteries, with or without the use of adjunctive therapy. A total of 6.7% (4/59) patients required a major limb amputation within 30 days despite successful recanalization, and one 30-day mortality was recorded. Complications included distal embolization (5), access site hematoma (2), and AKI (4). No major bleeding, hemolysis-induced AKI, or vessel dissection or perforation was observed. ConclusionsThe JETi device appears to be a safe and effective percutaneous treatment option in the management of ALI. It provides definitive treatment with a high technical success rate of 86% and a good safety profile.

Early Diagnosis and Treatment Outcomes of Fournier Gangrene in a Tertiary Center.

Fournier gangrene is an uncommon urological emergency caused by microbial agents, resulting in necrosis of the genitalia and perineum. This study aims to evaluate the outcomes of early diagnosis and management of Fournier gangrene at KAMC in Riyadh, Saudi Arabia. A retrospective cohort study was conducted at KAMC, Saudi Arabia. The study population included all adult patients diagnosed with Fournier gangrene between 2015 and 2022. Data analysis was performed using RStudio (RStudio, Boston, MA). Frequencies and percentages were used to present categorical data, while medians and interquartile ranges were used to express numerical variables. The study included 41 patients with Fournier gangrene, the majority (95.12%) being male with a median age of 60 years. The most prevalent comorbidity was diabetes mellitus (85.37%). Ten patients presented to the hospital with sepsis, two of whom were in shock. Within 90 days of admission, two of them had expired. This resulted in a 20% mortality rate among septic patients. The mean FGSI in patients who had died during hospital stays was approximately two times the mean in surviving patients (8.17 and 4.32, respectively). The most utilized imaging study was a CT scan (70.7%). Most patients had undergone multiple debridements (87.7%). The median number of debridements per patient was three, and the interval between each debridement was three days. The most frequent tissue culture finding was mixed organisms, followed by Escherichia coli. Regarding empiric antibiotics, tazocin was the most used, accounting for 22.0%. The most frequently performed adjunctive procedure was the placement of a suprapubic catheter, accounting for 41.5%. Roughly 43.90% required a blood transfusion. Within 90 days of admission, six patients had died, which makes the mortality rate 14.6%. Four of them had died within 30 days of admission (9.76%). Fournier gangrene is a surgical emergency that requires prompt attention and resuscitation, antibiotic therapy, and surgical debridement. The study identified the demographic factors of patients who presented with the disease and provided the incidence, mortality rate, and outcomes of the disease. It also identified specifics of the pharmacological and surgical management and hospital courses.
