A Giant Stent for Giant Cerebral Aneurysms-The Accero®-Rex-Stent.

Until now, giant intracranial aneurysms (GIAs) have in many cases been a vascular disease that was difficult or impossible to treat, not least due to the lack of availability of a large-format stent. In this multicentre study, we report on the first five clinical applications of the Accero®-Rex-Stents (Acandis, Pforzheim, Germany) in the successful treatment of fusiform cerebral giant aneurysms. The Accero®-Rex-Stents are self-expanding, braided, fully radiopaque Nitinol stents designed for aneurysm treatment. The stent is available in three different sizes (diameter 7-10 mm, length 30-60 mm) and intended for endovascular implantation in vessels with diameters of 5.5-10 mm. Five patients (all male, age 54.4 ± 8.1 years) with large fusiform aneurysms of the posterior circulation were treated endovascularly using the Accero®-Rex-Stents. There were no technical complications. One major ischemic complication occurred. A significant remodeling and reduction in the size of the stent-covered aneurysms was already seen in the short-term post-interventional course. The Accero®-Rex-Stents were successfully and safely implanted in all five patients with fusiform giant aneurysms, showing technical feasibility with promising initial results and significant aneurysm size reduction in already available follow-up imaging. With the Accero-Rex-Stents, a new device is available that offers another treatment option for rare cerebral fusiform giant aneurysms with very large parent vessels.

Post-interventional infectious complications in percutaneous transabdominal lymphatic interventions: an observational study

The purpose of this retrospective study was to evaluate the occurrence of infectious complications and inflammatory reactions after transabdominal lymphatic-interventions. 63 lymphatic-interventions were performed in 60 patients (male/female: 35/25; mean age 56 [9–85] years) [chylothorax n = 48, chylous ascites n = 7, combined chylothorax/chylous ascites n = 5]. Post-interventional clinical course and laboratory findings were analyzed in the whole cohort as well as subgroups without (group A; n = 35) and with peri-interventional antibiotics (group B; n = 25) (pneumonia n = 16, drainage-catheter inflammation n = 5, colitis n = 1, cystitis n = 1, transcolonic-access n = 2). No septic complications associated with the intervention occurred. Leucocytes increased significantly, peaking on post-interventional day-1 (8.6 ± 3.9 × 106 cells/mL vs. 9.8 ± 4.7 × 106 cells/mL; p = 0.009) and decreased thereafter (day-10: 7.3 ± 2.7 × 106 cells/mL, p = 0.005). CRP-values were pathological in 89.5% of patients already at baseline (40.1 ± 63.9 mg/L) and increased significant on day-3 (77.0 ± 78.8 mg/L, p < 0.001). Values decreased thereafter (day-15: 25.3 ± 34.4 mg/L, p = 0.04). In subgroup B, 13/25 patients had febrile episodes post-interventionally (pneumonia n = 11, cystitis n = 1, drainage-catheter inflammation n = 1). One patient developed biliary peritonitis despite continued antibiotics and underwent cholecystectomy. Baseline leucocytes and CRP-levels were higher in group B than A, but with comparable post-interventional profiles. Clinically relevant infectious complications associated with transabdominal lymphatic-interventions are rare irrespective of peri-interventional antibiotic use. Post-interventional elevation of leucocytes and CRP are observed with normalization over 10–15 days.

Outcomes and Patency of Endovascular Infrapopliteal Reinterventions in Patients With Chronic Limb-Threatening Ischemia

Purpose: Endovascular revascularization is the preferred treatment to improve perfusion of the lower extremity in patients with chronic limb-threatening ischemia (CLTI). Patients with CLTI often present with stenotic-occlusive lesions involving the infrapopliteal arteries. Although the frequency of treating infrapopliteal lesions is increasing, the reintervention rates remain high. This study aimed to determine the outcomes and patency of infrapopliteal endovascular reinterventions. Methods: This retrospective, multicenter cohort study of 3 Dutch hospitals included patients who underwent an endovascular infrapopliteal reintervention in 2015 up to 2021 after a primary infrapopliteal intervention for CLTI. The outcome measures after the reintervention procedures included technical success rate, the mortality rate and complication rate (any deviation from the normal postinterventional course) at 30 days, overall survival, amputation-free survival (AFS), freedom from major amputation, major adverse limb event (MALE), and recurrent reinterventions (a reintervention following the infrapopliteal reintervention). Cox proportional hazard models were used to determine risk factors for AFS and freedom from major amputation or recurrent reintervention. Results: Eighty-one patients with CLTI were included. A total of 87 limbs underwent an infrapopliteal reintervention in which 122 lesions were treated. Technical success was achieved in 99 lesions (81%). The 30-day mortality rate was 1%, and the complication rate was 13%. Overall survival and AFS at 1 year were 69% (95% confidence interval [CI], 55%–79%) and 54% (95% CI, 37%–67%), respectively, and those at 2.5 years were 45% (95% CI, 33%–56%) and 21% (95% CI, 11%–33%), respectively. Freedom from major amputation, MALE, and recurrent reinterventions at 1 year and 2.5 years were 59% (95% CI, 46%–70%) and 41% (95% CI, 25%–56%); 54% (95% CI, 41%–65%) and 36% (95% CI, 21%–51%); and 68% (95% CI, 55%–78%) and 51% (95% CI, 33%–66%), respectively. A Global Limb Anatomic Staging System score of III showed an increased hazard ratio of 2.559 (95% CI, 1.078–6.072; p=0.033) for freedom of major amputation or recurrent reintervention. Conclusions: The results of this study indicate that endovascular infrapopliteal reinterventions can be performed with acceptable 30-day mortality and complication rates. However, outcomes and patency were moderate to poor, with low AFS, high rates of major amputations, and recurrent reinterventions. Clinical Impact This multicenter retrospective study evaluating outcome and patency of endovascular infrapopliteal reinterventions for CLTI, shows that endovascular infrapopliteal reinterventions can be performed with acceptable 30-day mortality and complication rates. However, the short- and mid-term outcomes of the infrapopliteal reinterventions were moderate to poor, with low rates of AFS and a high need for recurrent reinterventions. While the frequency of performing infrapopliteal reinterventions is increasing with additional growing complexity of the disease, alternative treatment options such as venous bypass grafting or deep venous arterialization may be considered and should be studied in randomized controlled trials.

Liparthroplasty for Thumb Carpometacarpal Joint Osteoarthritis: A Case Series with Median 5 Years of Follow-Up.

Liparthroplasty has recently been discussed as a promising bridging therapy after failed conservative treatment options to postpone arthroplasty surgery of the thumb carpometacarpal joint as long as possible. The current study investigates the sustainability of this method in seven stage II and twenty-four stage III osteoarthritis patients (twenty-seven female and four male cases). Data were evaluated preinterventionally, six months postinterventionally, and two years postinterventionally, as well as a final follow-up assessment after median 5.1 years. We found a significant reduction of all postinterventional disabilities of the arm, shoulder, and hand (dash) scores and pain levels compared to the ones prior to liparthroplasty. Moreover, we even detected a reduction in both parameters within the postinterventional course, so that the DASH scores of our final investigation were significantly lower than the values after six months. Furthermore, 12 of our 31 cases demanded a surgical conversion due to recurrence of symptoms. A binary regression analysis found smokers to have 11 times higher odds for therapy failure, leading to surgical conversion. Seventeen out of nineteen patients in our final assessment stated that they were pleased with liparthroplasty. Due to favorable mid-term outcomes of 61% of the 31 initially treated patients, we recommend liparthroplasty as a reliable bridging therapy for preserving joint integrity as long as possible, especially in non-smoking patients.

Upper gastrointestinal bleeding related to an eroded gastrosplenic collateral lately after splenic artery embolization

BackgroundUpper gastrointestinal, non-variceal haemorrhage can be related to various etiologies, including peptic ulcer, neoplasm, gastritis, Dieulafoy lesions and other, rare underlying diseases. Here, we describe another, yet unreported etiology of gastric bleeding.Case presentationA 49-year-old man presented with melena; gastroscopy revealed blood in the stomach without active bleeding source. Computed tomography angiography demonstrated a cluster of enlarged gastrosplenic arterial collaterals in the gastric wall and coils in the splenic artery, related to an embolization procedure 30-years ago for splenic trauma. Definitive treatment included catheter-directed glue embolization of the left gastric artery and the enlarged gastrosplenic collaterals. The postinterventional course was uneventful and no recurrence of upper gastrointestinal bleeding was noted after 6 months of follow-up.ConclusionsUpper gastrointestinal bleeding associated with eroded gastrosplenic collaterals, related to previous splenic artery embolization, can be successfully treated with glue-embolization.

A new variant of Abernethy malformation treated by transhepatic interventional closure: a case report

BackgroundCongenital portosystemic shunts (CPSS) are rare vascular malformations and can be classified into extrahepatic and intrahepatic shunts. Extrahepatic CPSS, also termed Abernethy malformations are associated with severe long-term complications including portopulmonary hypertension, liver atrophy, hyperammoniemia and hepatic encephalopathy. We report a hitherto undescribed variant of Abernethy malformation requiring an innovative approach for interventional treatment.Case presentationWe describe a 31-year-old patient following surgical repair of atrioventricular septal defect at the age of 6 years. In the long-term follow-up he showed persistent pulmonary hypertension which deteriorated despite dual pulmonary vasodilative treatment. When he developed arterial desaturation and symptomatic hyperammoniemia detailed reassessment revealed as underlying cause a hitherto undescribed variant of Abernethy malformation connecting the portal vein with the right lower pulmonary vein. Following interdisciplinary discussions we opted for an interventional approach. Since the malformation was un-accessible to interventional closure via antegrade venous or retrograde arterial access, a transhepatic percutaneous puncture of the portal vein was performed. Temporary balloon occlusion of the malformation revealed only a slight increase in portal venous pressure. Interventional occlusion of the large vascular connection was achieved via this transhepatic approach by successive implantation of two large vascular occluding devices. The postinterventional course was unremarkable and both ammonia levels and arterial saturation normalized at follow-up of 12 months.ConclusionsPortal vein anomalies should be included in the differential diagnoses of pulmonary hypertension or pulmonary arterio-venous malformations. Based on careful assessment of the anatomy and testing of portal vein hemodynamics interventional therapy of complex Abernethy malformations can be performed successfully in specialized centers.

Endovascular Treatment of Intracranial Aneurysms in Small Peripheral Vessel Segments-Efficacy and Intermediate Follow-Up Results of Flow Diversion With the Silk Vista Baby Low-Profile Flow Diverter.

Background and Purpose: Low-profile flow diverter stents (FDS) quite recently amended peripheral segments as targets for hemodynamic aneurysm treatment; however, reports on outcomes, especially later than 3 months, are scarce. This study therefore reports our experience with the novel silk vista baby (SVB) FDS and respective outcomes after 8 and 11 months with special respect to specific adverse events.Materials and Methods: Forty-four patients (mean age, 53 years) harboring 47 aneurysms treated with the SVB between June 2018 and December 2019 were included in our study. Clinical, procedural, and angiographic data were collected. Follow-ups were performed on average after 3, 8, and 11 months, respectively. Treatment effect was assessed using the O'Kelly Marotta (OKM) grading system.Results: Overall, angiographic follow-ups were available for 41 patients/45 aneurysms. Occlusion or significant reduction in aneurysmal perfusion (OKM: D1, B1–B3 and A2–A3) was observed in 98% of all aneurysms after 8 months. Only 2% of the treated aneurysms remained morphologically unaltered and without an apparent change in perfusion (OKM A1). Adverse events in the early post-interventional course occurred in seven patients; out of them, mRS-relevant morbidity at 90 days related to FDS treatment was observable in two patients. One death occurred in the context of severe SAH related to an acutely ruptured dissecting aneurysm of the vertebral artery.Conclusion: The SVB achieves sufficient occlusion rates of intracranial aneurysms originating from peripheral segments, which are comparable to prior established conventional FDS with acceptably low complication rates. However, alteration of a hemodynamic equilibrium in distal localizations requires special attention to prevent ischemic events.

Fractional ablative carbon dioxide laser treatment of facial scars: Improvement of patients' quality of life, scar quality, and cosmesis.

Disfiguring facial scars can be a massive burden on patients' psychosocial health and severely impact patients' self-esteem. The aim of this study was to analyze whether ablative fractional carbon dioxide laser (CO2-AFL) treatment can positively influence facial scarring and quality of life (QoL) while improving the aesthetic appearance. Patients with facial scars who had received CO2-AFL treatment between May 2019 and May 2020 were included in a retrospective study. The post-interventional course and patient and/or observer reported outcomes were inquired before and three months after treatment. Primary outcomes were changes in the Patient and Observer Scar Scale (POSAS) and QoL (Short Form (SF) 36). In addition, two independent examiners evaluated the aesthetic outcome by comparing initial scarring with the post-intervention results using photographs. A total of 16 patients with facial scars were included. Most of the scars were caused by burns (43.8%) or trauma (31.3%). The post-interventional course was uneventful. Overall POSAS scores improved decisively for both observers (n=2) and patients (n=16) (p<0.001 and p<0.001). Also, there was an improvement in QoL with an increase in emotional well-being (p=0.043) and social functioning (p=0.01). Furthermore, the aesthetic outcome was significantly enhanced (p=0.001) after treatment. The CO2-AFL offers a safe and effective treatment for disfiguring facial scars. We have shown that improvement of scar appearance and scar quality was meaningful to the patient, with a significant impact on a patient's life quality. Based on these findings we suggest including the CO2-AFL in the facial scar treatment concept.

Acute kidney injury may impede results after transcatheter aortic valve implantation.

IntroductionSevere complications after transcatheter aortic valve implantation (TAVI) are rare due to increasing procedural safety. However, TAVI procedure-related haemodynamic instability and increased risk of infection may affect renal functional reserve with subsequent renal acidosis and hyperkalaemia.ObjectiveIn this study, we investigated incidence, modifiable risk factors and prognosis of acute kidney injury (AKI) and AKI complicated by hyperkalaemia, pulmonary oedema or metabolic acidosis after TAVI.MethodsIn a retrospective single-centre study, 804 consecutive patients hospitalized during 2017 and 2018 for elective TAVI were included. AKI was defined according to the ‘Kidney Disease Improving Global Outcome’ (KDIGO) initiative. Variables on co-morbidities, intra-/post-interventional complications and course of renal function up to 6 months after index-hospitalization were assessed. In multivariate regression analyses, risk factors for the development of AKI, complicated AKI, renal non-recovery from AKI and in-hospital mortality were determined.ResultsIncidence of AKI was 13.8% (111/804); in-hospital mortality after TAVI was 2.3%. AKI was an independent risk factor for in-hospital mortality, odds ratio (OR) 10.3 (3.4–31.6), P < 0.001, further increasing to OR = 21.8 (6.6–71.5), P < 0.001 in patients with AKI complicated by hyperkalaemia, pulmonary oedema or metabolic acidosis, n = 57/111 (51.4%). Potentially modifiable, interventional factors independently associated with complicated AKI were infection [OR = 3.20 (1.61–6.33), P = 0.001] and red blood cell transfusion [OR = 5.04 (2.67–9.52), P < 0.001]. Valve type and size, contrast volume and other intra-interventional characteristics, such as the need for tachycardial pacing, did not influence the development of AKI. Eleven of 111 (9.9%) patients did not recover from AKI, mostly affecting patients with cardiac decompensation. In 18/111 (16.2%) patients, information concerning AKI was provided in discharge letter. Within 6 months after TAVI, higher proportion of patients with AKI showed progression of pre-existing chronic kidney disease compared with patients without AKI [14/29, 48.3% versus 54/187, 28.9%, OR = 2.3 (95% confidence interval 1.0–5.1), P = 0.036].ConclusionsAKI is common and may impede patient outcome after TAVI with acute complications such as hyperkalaemia or metabolic acidosis and adverse renal function until 6 months after intervention. Our study findings may contribute to refinement of allocation of appropriate level of care in and out of hospital after TAVI.

Transient acute right coronary artery deformation during transcatheter interventional tricuspid repair with the Cardioband tricuspid system.

The Cardioband tricuspid valve reconstruction system is a size-adjustable tricuspid reconstruction device for interventional treatment of tricuspid regurgitation (TR). Contraction of the device after successful implantation can be associated with an acute deformation of the right coronary artery (RCA). The aim of this study was to provide data on the persistence and clinical significance of acute RCA deformation following Cardioband implant procedures. Data from all patients with intraprocedural RCA deformation during Cardioband implantation were collected from four centres between October 2018 and January 2020. Control angiographies were performed in all of these patients before discharge. RCA deformation occurred in 14 out of 51 patients. Follow-up coronary angiography showed a complete resolution of deformation in all cases while patients remained clinically asymptomatic and had an uneventful post-interventional course. Intraprocedural coronary stent implantation was performed in two of the earlier cases according to the personal assessment of the implanters. RCA deformation is relatively frequent following interventional tricuspid annuloplasty but appears to be completely reversible in the absence of flow impairment or vascular damage. Based on our early experience watchful waiting is the most appropriate strategy to avoid unnecessary coronary interventions.

Pain in the aftermath of minimal invasive treatment for unilateral incompetence of the great saphenous vein.

Assessment of postprocedural pain after minimal invasive treatment of unilateral incompetence of the great saphenous vein. A total of 85 patients treated with endovenous laser ablation (1470 nm) in combination with foam sclerotherapy and evulsions reported postprocedural pain on a visual analogue scale (0-10) during 28 days after treatment. A mean pain reduction from 3.9 on the first postinterventional day to 0.3 was noted during the observation time. After 28 days, 7% of patients had a visual analogue scale >1. Higher body mass index was strongly associated with more pain during the whole follow-up period (p < 0.01). Higher energy application per cm vein and greater great saphenous vein diameter showed more pain in the first week. Other factors like clinical stage CEAP classification, combination of laser with avulsions and/or sclerotherapy, season of treatment timepoint, and age or sex did not influence postinterventional pain course. Higher body mass index and higher energy application per cm are associated with more postprocedural pain after endovenous laser ablation.

Pulmonary Hypertension in Adults with Congenital Heart Disease: Real-World Data from the International COMPERA-CHD Registry.

Introduction: Pulmonary hypertension (PH) is a common complication in patients with congenital heart disease (CHD), aggravating the natural, post-operative, or post-interventional course of the underlying anomaly. The various CHDs differ substantially in characteristics, functionality, and clinical outcomes among each other and compared with other diseases with pulmonary hypertension. Objective: To describe current management strategies and outcomes for adults with PH in relation to different types of CHD based on real-world data. Methods and results: COMPERA (Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension) is a prospective, international PH registry comprising, at the time of data analysis, >8200 patients with various forms of PH. Here, we analyzed a subgroup of 680 patients with PH due to CHD, who were included between 2007 and 2018 in 49 specialized centers for PH and/or CHD located in 11 European countries. At enrollment, the patients’ median age was 44 years (67% female), and patients had either pre-tricuspid shunts, post-tricuspid shunts, complex CHD, congenital left heart or aortic disease, or miscellaneous other types of CHD. Upon inclusion, targeted therapies for pulmonary arterial hypertension (PAH) included endothelin receptor antagonists, PDE-5 inhibitors, prostacyclin analogues, and soluble guanylate cyclase stimulators. Eighty patients with Eisenmenger syndrome were treatment-naïve. While at inclusion the primary PAH treatment for the cohort was monotherapy (70% of patients), with 30% of the patients on combination therapy, after a median observation time of 45.3 months, the number of patients on combination therapy had increased significantly, to 50%. The use of oral anticoagulants or antiplatelets was dependent on the underlying diagnosis or comorbidities. In the entire COMPERA-CHD cohort, after follow-up and receiving targeted PAH therapy (n = 511), 91 patients died over the course of a 5-year follow up. The 5-year Kaplan–Meier survival estimate for CHD associated PH was significantly better than that for idiopathic PAH (76% vs. 54%; p < 0.001). Within the CHD associated PH group, survival estimates differed particularly depending on the underlying diagnosis and treatment status. Conclusions: In COMPERA-CHD, the overall survival of patients with CHD associated PH was dependent on the underlying diagnosis and treatment status, but was significantly better as than that for idiopathic PAH. Nevertheless, overall survival of patients with PAH due to CHD was still markedly reduced compared with survival of patients with other types of CHD, despite an increasing number of patients on PAH-targeted combination therapy.

REFRAMING STUDENTS’ NEGATIVE CONCEPTIONS OF FAILURE: AN ACTION RESEARCH

The fear of academic failure can compound other challenges that students are already facing in their lives, and this can take a toll on their mental and emotional states, their relationships with others, and their learning capacities. This article presents findings of an action research that was carried out with 35 postgraduate students from two classes, with aims to reframe their conception of fear of failure as valuable lesson opportunities, by means of getting them to participate in experiential and purposeful activities in a safe learning space. It aims to see if these students would have become less fearful of failures by Week 15. In addition to sharing personal anecdotes of failure, students were given challenging class work, reminded of failure-success catch-phrases, given honest and critical (but compassionate) feedback of their performance. The collected data include students’ fear of failure index scores, pre (Week 1) and post (Week 15) intervention course feedback of their fear of failure. The analysis shows that the methods seem to have a positive effect in mitigating fears of failure, however, the research also shows some caveats and variables that can inhibit the facilitation and the effectiveness of the pedagogical methods. It is hoped this research can also aid other educators in improving and innovating their pedagogy practices, in order to help students reframe their conceptions of failure.&#x0D; &#x0D; Keywords: Action research, experiential learning, fear of failure, reframing beliefs, safe learning space&#x0D; &#x0D; Cite as: Yoong, D., &amp; Saffari, N.

Where Have All the Punctures Gone? An Analysis of Thoracic Duct Embolizations.

To determine how frequently and how severely intra-abdominal structures are affected by transabdominal thoracic duct embolization (TDE). Thirty-five TDE procedures in 35 patients (22 male; mean age, 57 y; age range, 10-79 y) with therapy-refractory chylous effusions were evaluated in which radiopaque embolization material outlined the access route on postinterventional CT. CT data were analyzed by 2 TDE-experienced radiologists. Abdominal structures and organs transgressed by the access route were recorded, and findings were correlated with clinical postinterventional course with follow-up of at least 44 days. Intra-abdominal structures/organs transgressed most often by the access route were the liver (n= 28), crus of the diaphragm (n= 25), pancreas (n= 14), portal vein (n= 10), duodenum (n= 7), inferior vena cava (n= 5), colon (n= 3), left renal vein (n= 2), pleura (n= 2), pericardium (n= 2), and gastric sleeve (n= 2). Pancreatitis was observed in 1 of 14 patients after pancreatic transgression. One case of clinically occult pulmonary glue migration occurred on catheter pullback through the left renal vein. Biliary peritonitis was observed after gallbladder puncture, necessitating cholecystectomy in 1 of 2 transbiliary punctures. No other relevant procedure-related complications such as hemorrhages or infectious complications were observed. Despite transgression of intra-abdominal structures, puncture- and access-related complications of TDE are rare. Transpancreatic manipulations are reasonably well tolerated.

Long-Term Effectiveness of a Brief Restorative Justice Intervention.

This research investigated the effectiveness of a brief Restorative Justice Intervention. Probationers who attended a Restorative Justice Intervention ( n = 383) were compared with probationers receiving treatment as usual ( n = 130) over a 2- to 6-year follow-up period. The proportion of individuals who recidivated in the control condition ( n = 89, 68.46%) were higher compared with those who recidivated in the intervention condition ( n = 127, 33.16%; z = 7.04, p < .001). In addition, among those who recidivated, those in the intervention condition did so less frequently. Qualitative analyses from a postintervention course evaluation given only to the intervention condition showed that 50% of probationers acknowledged an empathic understanding associated with participation. This brief intervention has a positive multilevel impact on restorative justice. Implications of these effects are discussed.

A Unique All-Payer Rate-Setting System Controls the Cost but Not the Racial Disparity in Lower Extremity Revascularization Procedures

Patients with peripheral arterial disease often have high comorbidity burden that may complicate post-interventional course and drive increased health-care expenditures. Racial disparity had been observed in lower extremity revascularization (LER) patterns and outcomes. In 2014, Maryland adopted an all-payer rate-setting system to limit the rising hospitalization costs. This resulted in an aggregate payment system in which hospital compensation takes place as an overall per capita expenditure for hospital services. We sought to examine racial differences and other patient-level factors that might lead to discrepancies in LER hospital costs in the State of Maryland. We used International Classification of Diseases, Ninth Revision codes to identify patients who underwent infrainguinal open bypass (open) and endovascular repair (endo) in the Maryland Health Services Cost Review Commission database (2009-2015). Multivariable generalized linear model regression analysis was conducted to report cost differences adjusting for patient-specific demographics, comorbidities, and insurance status. Logistic regression analysis was used to assess quality metrics: intensive care unit (ICU) admission, 30-day readmission, protracted length of stay (pLOS) (endo: pLOS >9, open: pLOS > 10days) and in-hospital mortality. Among patients undergoing open, costs were higher for nonwhite patients (African-American [AA]: $6,092 [4,682-7,501], other: $3,324 [437-6,212]; both P≤0.024), diabetics ($2,058 [837-3,279]; P<0.001), and patients with Medicaid had an increased cost over Medicare patients by $4,325 (1,441-7,209). Critical limb ischemia (CLI) was associated with $5,254 (4,014-6,495) risk-adjusted cost increment. In addition, AA patients demonstrated higher risk-adjusted odds of ICU admission (adjusted odds ratio [aOR] [95% confidence interval {CI}]:1.65 [1.46-1.86]; P<0.001) and pLOS (aOR [95% CI]: 1.56 [1.37-1.79]; P<0.001) than their white counterparts. For patients undergoing endo, costs were higher for nonwhite patients (AA: $2,642 [1,574-3,711], other: $4,124 [2,091-6,157]; both P<0.001). Patients with CLI and heart failure had increased costs after endo. AA patients were more likely to be readmitted or stayed longer after endo (1.16 [1.03-1.29], 1.34 [1.21-1.49]; both P<0.010, respectively). The overall cost trend was rapidly increasing before all-payer rate policy implementation but it dramatically plateaued after2014. This study showed that the all-payer rate-setting system has curbed the LER rising costs, but these costs remained disproportionally higher for disadvantaged populations such as AA and Medicaid communities. This underpins the existing racial disparity in LER. AA patients had higher LER costs, most likely driven by extended hospitalization and ICU admission. Efforts could be directed to evaluate the contributing socioeconomic factors, invest in primary prevention of comorbid conditions that had shown to be associated with prohibitive costs, and identify mechanisms to overcome the existing racial disparity in LER within the promising cost-saving payment system at the State of Maryland.

The value of short-term pain relief in predicting the long-term outcome of 'indirect' cervical epidural steroid injections.

The predictive value of short-term arm pain relief after 'indirect' cervical epidural steroid injection (ESI) for the 1-month treatment response has been previously demonstrated. It remained to be answered whether the long-term response could be estimated by the early post-interventional pain course as well. Prospective observational study, following a cohort of n = 45 patients for a period of 24months after 'indirect' ESI for radiculopathy secondary to a single-level cervical disk herniation (CDH). Arm and neck pain on the visual analog scale (VAS), health-related quality of life with the Short Form-12 (SF-12), and functional outcome with the Neck Pain and Disability (NPAD) Scale were assessed. Any additional invasive treatment after a single injection (second injection or surgery) defined treatment outcomeas 'non-response'. At 24months, n = 30 (66.7%) patients were responders and n = 15 (33.3%) were non-responders. Non-responders exited the follow-up at 1month (n = 10), at 3months (n = 4), and at 6months (n = 1). No patients were injected again or operated on between the 6- and 24-month follow-up. Patients with favorable treatment response at 24months had significantly lower VAS arm pain (p < 0.05) than non-responders at days 6, 8-11, and at the 3-month follow-up. The previously defined cut-off of > 50% short termpain reduction was not a reliable predictor of the 24-month responder status. SF-12 and NPAD scores were better among treatment responders in the long term. Patients who require a second injection or surgery after 'indirect' cervical ESI for a symptomatic CDH do so within the first 6months. Short-term pain relief cannot reliably predict the long-term outcome.

Acute fissuration of a giant splenic artery aneurysm detected by point-of-care ultrasound: case report

BackgroundEpigastric pain is frequent in Emergency Medicine and remains a challenging situation. Besides benign etiologies such as gastritis or uncomplicated cholelithiasis, it could reveal myocardial infarction or vascular disease. Point-of-care ultrasound (POCUS) could be performed in such situation.Case presentationA healthy 66-year-old man with no previous medical history was admitted to the Emergency Department for a rapid onset epigastric pain. He reported taking non-steroidal anti-inflammatories for 1 week prior to admission. His pain had rapidly subsided and the physical examination was inconclusive. ECG and blood samples were normal. POCUS revealed a vascular mass located between the spleen and the left kidney measuring 80 * 74 mm associated with small amounts of free peritoneal fluid. Computed tomography diagnosed a fissurated giant aneurysm of the splenic artery. The aneurysm was managed emergently by endovascular exclusion by selective splenic artery embolization. The post-intervention course was uneventful and the patient was discharged home 3 days later. The patient has remained free from any complications of the embolization 6 months after the procedure.ConclusionSpontaneously regressive epigastric pain with a normal physical and biology/ECG should not necessarily reassure the physician, in particular if patients have cardiovascular risk factors. A POCUS should be considered for these patients.

Stent-assisted coiling of a ruptured vertebrobasilar junction aneurysm via direct vertebral artery puncture

A 78-year-old patient was admitted with subarachnoid hemorrhage caused by rupture of a broad-based vertebrobasilar junction aneurysm. Direct endovascular access to the vertebrobasilar circulation was not possible due to chronic...

Surgical Management of Iatrogenic Perforation of the Gastrointestinal Tract: 15 Years of Experience in a Single Center

Gastrointestinal (GI) tract perforation during endoscopy is a rare but severe complication. The aim of this study was to determine predictors of morbidity and mortality after iatrogenic endoscopic perforation. All cases with iatrogenic endoscopic perforation receiving surgery at a tertiary referral center in a 15-year period (2000-2015) were retrospectively analyzed. Demographics, type of endoscopy, site of perforation, operative procedure, morbidity and mortality were analyzed. Multiple logistic regression was used to identify parameters predicting survival. A total of 106.492 endoscopies were performed, and 82 (0.08%) patients were diagnosed with GI perforation. Most perforations (63.4%) occurred in the lower GI tract, compared to 36.6% in the upper GI tract. In 21 cases (25%), perforation was noticed during endoscopy, whereas 61 perforations (75%) were diagnosed during the further clinical course. Operative care was applied within 24h in 61%. Surgery of perforations was almost completely performed maintaining the intestinal continuity (68%), whereas diversion was performed in 32%. Mortality was associated with age above 70 (OR 4.89, p=0.027), ASA class>3 (OR 4.08, p=0.018), delayed surgery later than 24h after perforation (OR 5.9, p=0.015), peritonitis/mediastinitis intraoperatively (OR 4.68, p=0.031) and severe postoperative complications with a Clavien-Dindo grade ≥III (OR 5.12, p=0.023). The prevalence of iatrogenic endoscopic perforation is low, although it is associated with a serious impact on morbidity and mortality. Delayed management worsens prognosis. To achieve successful management of endoscopic perforations, early diagnosis is essential in cases of deviation from the normal post-interventional course, especially in elderly.
