Efficacy and safety of a dedicated venous stent for the treatment of iliofemoral venous obstruction: A single center experience

Abstract

Background

Endovascular recanalization with venous stenting is the preferred treatment for iliofemoral venous obstruction. We reviewed our institutional experience and mid-term outcomes with endovascular therapy for iliofemoral venous obstruction using the Venovo^TM Self-expanding Venous Stent (BARD Peripheral Vascular, Inc., Tempe, AZ, USA).

Methods

Between October 2022 and March 2024, patients with iliofemoral venous obstruction treated with Venovo^TM Self-expanding Venous Stents were retrospectively analyzed. Patients were monitored at 3, 6, and 12 months. The primary endpoint was 12-month primary patency, defined as computed tomography venography-derived stenosis <50% and no target venous revascularization. Secondary endpoints included stent intimal hyperplasia and pain venous clinical severity scores (VCSSs).

Results

We evaluated 51 limbs from 40 patients (mean age: 61.7 ± 10.7 years; 26 females), including three acute deep venous thrombosis (DVT)cases, six post-thrombotic syndrome (PTS) cases, and 42 non-thrombotic iliofemoral vein lesion cases. All (100%) underwent successful endovascular treatment, with five undergoing combined stent deployment. The interventional operation-related complication rate was 1/51 (1.96%). The median follow-up was 14.6 months (range: 12–18 months). The primary patency rate at 1 year was 90%. Freedom from stent intimal hyperplasia at 12 months was 74.51% (38/51), and 3.92% (2/51) had in-stent stenosis >50%, which was reduced after high-pressure balloon dilation at 6 months. The mean VCSS decreased from a baseline of 13.1.7 ± 3.7 to 3.3 ± 1.6 at 12 months (p < .0001). No complications were noted during follow-up.

Conclusions

Stenting iliofemoral venous obstruction using the Venovo^TM Self-expanding Venous Stent appears to be safe and effective, with a high rate of 1-year clinical patency and a low reintervention rate.
