Endovascular Treatment for Iliofemoral Vein Thrombosis with Composite Stents

Abstract

To evaluate the applicability of endovascular treatment for iliofemoral vein thrombosis with composite stents. Between September 2013 and August 2016, 29 consecutive patients underwent endovascular therapy with composite stents for iliofemoral vein thrombosis and were followed up at our institution. All the patients with acute or chronic iliofemoral vein thrombosis enrolled in this study were evaluated by color Doppler ultrasonography and diagnosed by venography. Treatment measures and related complications were recorded, and cumulative stent patency was assessed with Kaplan-Meier curves. Patients with acute iliofemoral vein thrombosis (n=7) were successfully treated with catheter-directed thrombolysis treatment, balloon angioplasty, and stents, whereas patients (n==22) with chronic deep vein thrombosis were treated successfully by balloon angioplasty and stent only. Among all patients, 2 stents were inserted in 25 patients, whereas 3 stents were deployed in 4 patients. Endovascular treatment for iliofemoral vein thrombosis with laser-cut stents combined with Wallstents showed primary patency of treated limbs at 6, 12, and 24months was 96.6%, 93.1% and 93.1%, respectively. Mean duration of follow-up was 23months, and there was no occurrence of contralateral vein thrombosis during follow-up by ultrasound. Iliofemoral vein thrombosis was successfully recanalized by endovascular therapy with composite stents, and there was no occurrence of contralateral vein thrombosis by ultrasound during follow-up.
