Article Abstract

Objective: To evaluate the association between subclavian vein patency and health-related quality of life following supraclavicular thoracic outlet decompression among patients with venous thoracic outlet syndrome.

Methods: Patients who underwent supraclavicular thoracic outlet decompression (i.e. first thoracic rib resection, scalenectomy, and subclavian venolysis) were identified from a prospectively maintained database. Demography, perioperative venography, and catheter-directed interventions were recorded. The primary endpoints were subclavian vein patency and health-related quality of life following decompression. The association between subclavian vein patency and health-related quality of life was evaluated in unadjusted and logistic regression analyses.

Results: Among 1,032 patients with TOS who underwent surgery (2007-2021), 275 patients presented with venous thoracic outlet syndrome. Two-hundred and twenty-five patients (81.8%) underwent preoperative venography; 221 (98.2%) had completely or partially stenosed subclavian veins. Preoperative catheter-based interventions were performed among 166 patients (60.4%); stenosis remained in 130 patients (78.3%). Postoperatively, 216 patients (78.5%) underwent routine venography; improvement in stenosis was observed in 54 (25.0%). Additional catheter-based interventions were performed in 155 patients (56.4%) with improvement in stenosis observed in 131 patients (84.5%). At a median follow up of 279 days [IQR 95, 674], 94.0% of patients reported improvement in health-related quality of life. Improvement in subclavian vein patency was associated with improved health-related quality of life (adjusted odds ratio 2.19 [95%CI 1.12-4.28], p=0.021).

Conclusions: Subclavian vein patency is associated with improved health-related quality of life among patients with venous thoracic outlet syndrome. Effective venolysis during thoracic outlet decompression with perioperative catheter-directed intervention contributes most significantly to vein patency.

Background: Disseminated cancer can complicate the decision-making for major surgery, as patients can be poor surgical candidates and have potentially limited life expectancy. This study aimed to evaluate the 30-day postoperative outcomes of infrainguinal bypass in patients with disseminated cancer using a large-scale national database.

Methods: Adult patients with and without disseminated cancer who underwent infrainguinal bypass were identified in the ACS-NSQIP database from 2011-2023.

Objective- Surgically created upper extremity arteriovenous fistulae (AVF) are the preferred vascular access for patients requiring dialysis. It is estimated, however, that 50% of AVF fail within one year due to aggressive neointimal hyperplasia, which significantly increases morbidity and mortality. Matrix metalloproteinase-3 (MMP-3), also known as stromelysin-1, is a member of the metalloproteinase family that plays a critical role in the pathogenesis of many human disorders by degrading extracellular matrix and regulating molecular signaling pathways.

Background: Saphenous vein graft (SVG) failure remains a substantial challenge after coronary artery bypass graft (CABG). LDL cholesterol (LDL-C) is a causal risk factor for atherosclerosis, but its role in SVG failure is not well established. We evaluated whether early initiation of intensive LDL-C lowering with evolocumab could reduce SVG failure.

A 49-year-old female presented with subacute onset of severe worsening bilateral lower extremity swelling. Bilateral iliac venous thrombus and extensive thrombus of the inferior vena cava with extension to the right atrium and bilateral segmental pulmonary emboli was identified on imaging. She was initiated on therapeutic anticoagulation prior to undergoing percutaneous mechanical thrombectomy with the RevCore TM device (Inari Medical, Irvine, CA) with retrieval of white, relatively well-formed organized clot vs mass.
