Interventional treatment of iliofemoral venous obstruction through popliteal vein puncture

Objective: To determine the clinical value of popliteal vein puncture in the interventional treatment of iliofemoral venous obstruction. Methods: Popliteal vein puncture and synthetic interventioal therapy were performed in 58 cases, including catheter-directed thrombolysis in 42 cases, transcatheter aspiration in 25 cases, thrombectomy in 49 cases, angioplasty in 41 cases, and stenting in 35 cases, and inferior vena cava filter was inserted in 52 cases. The mean kind of interventional therapy performed in each patient was 5.2. The total efficiency was graded on a scale of 1 (excellent), 2 (good), 3 (mild), and 4 (no changes) according to the follow-up venography and physical sign. Anticoagulation therapy for 1 month and antiplatelet for 6 months were performed after dischargement and follow-up venography was performed after six months. Results: The technical successful rate of popliteal vein puncture was 96.7% (58/60). Two popliteal vein puncture failed without ultrasound or fluoroscopy guidance. The efficiency of 58 cases at discharge was as follows: 19 of grade 1, 30 of grade 2, 8 of grade 3, and 1 of grade 4, respectively. 42 cases had six months follow-up data including 18 grade 1, 20 of grade 2, 1 of grade 3, and 3 of grade 4, respectively. Conclusion: Interventional treatment of iliofemoral venous obstruction by popliteal vein puncture is safe and effective. (authors)
