Although venous stent placement is an established treatment for patients with deep vein thrombosis (DVT) and post-thrombotic syndrome (PTS), stent patency rate may be as low as 80% at 12 months. Treatment of stent occlusion requires the removal of a large amount of fresh or organized thrombus from stents with a diameter of 12-20 mm. The feasibility of large-bore rotational thrombectomy in combination with angioplasty to treat thrombosed venous iliofemoral or inferior vena cava stents has not been investigated yet.

Methods: We used nationwide, patient-level data including all patients aged 15 years or older hospitalized for PE in Switzerland from 2003 to 2022, amounting to N=180,600.
Background: The global impact of the COVID-19 pandemic has prompted the search for strategies to improve outcomes in affected individuals, including those initially managed in outpatient settings. Thromboembolic events have been reported as a concerning complication.
Objectives: The aim of this study was to evaluate efficacy and safety of primary thromboprophylaxis in outpatients with COVID-19.
Article Synopsis
- This study aimed to evaluate a new classification system for chronic venous obstruction (CVO) patients who have undergone successful medical procedures across 13 vascular centers from 2015 to 2019.
- Researchers analyzed the data of 1,033 CVO patients, classifying them into five categories based on the severity and location of their condition, and assessed stent deployment and complications alongside follow-up outcomes.
- Results showed that primary patency rates varied significantly among the classifications, with lower rates indicating more severe CVO, and identified key predictors of patency loss such as CVO type and the total number of stents used, suggesting the need for further validation of this classification system in future research.
Background: The pathophysiology of median arcuate ligament syndrome (MALS) is poorly understood. The diagnostic process remains inadequately standardized, with an absence of precise criteria to guide therapeutic management.
Methods: We studied consecutive subjects referred to the Department of Angiology at the University Hospital of Zurich over the past 17 years due to suspected MALS.
