What this trial studies

This observational study aims to assess the feasibility of mechanical thrombectomy in patients with symptomatic acute or subacute iliofemoral or caval deep vein thrombosis, diagnosed through CT imaging. It includes both retrospective and prospective data collection from patients admitted to the Vascular Surgery Unit. The study will follow standard clinical practices for treatment, including anticoagulation therapy prior to the procedure and monitoring of patients post-treatment. The focus is on understanding the effectiveness and safety of this intervention in a real-world clinical setting.

Why it matters

Potential benefit: If successful, this study could improve treatment options for patients suffering from deep vein thrombosis, potentially leading to better outcomes.

How similar studies have gone: Other studies have shown promising results with mechanical thrombectomy for similar conditions, indicating potential for success in this approach.
