Clinical value of profunda femoral vein thrombosis clearance in endovascular treatment of acute lower extremity deep vein thrombosis

Abstract

Objective To evaluate the safety and efficacy of profunda femoral vein thrombosis clearance in endovascular treatment of acute lower extremity deep venous thrombosis (DVT). Methods From January 2022 to September 2023, clinical data of acute lower extremity DVT patients who underwent percutaneous mechanical thrombectomy (PMT) for profunda femoral vein thrombosis were retrospectively analyzed. The 12-month primary patency rate of iliofemoral vein and incidence of post-thrombotic syndrome(PTS) were analyzed. Results Twenty-two patients were included in the study, and all patients underwent PMT for profunda femoral vein thrombosis. Five patients were treated through the contralateral common femoral vein via crossover approach, and 17 patients were treated through the contralateral common femoral vein combined with the ipsilateral deep vein approach. The 12-month primary patency rate of iliofemoral vein was 90.9% (20/22), and the incidence of PTS was 9.1% (2/22). Conclusions For patients with acute lower extremity DVT undergoing endovascular treatment, PMT for profunda femoral vein thrombosis is safe and effective, achieving good primary patency of iliofemoral vein and low incidence of PTS.
