N2 - Purpose: To assess retrospectively 30-day, 1-year, and 3-year patency of chronically occluded iliofemoral venous thrombotic lesions treated with stent placement in a case series from a single institution. Materials and Methods: Records of 189 consecutive patients treated by interventional radiology for iliofemoral venous occlusions between March 1, 2003, and December 1, 2008, were retrospectively reviewed. A total of 89 patients (27 men; median age, 46.2 y) with chronic iliac or iliofemoral deep vein thrombosis without involvement of the inferior vena cava met criteria for analysis. Results: All patients (91 limbs) successfully underwent placement of venous self-expanding stents. Patency rate at discharge was 100%. Following the index procedure, mean pressure gradient across the lesion decreased from 5.63 mm Hg (95% CI, 3.51-7.75) to 0.71 mm Hg (95% CI, 0.08-1.34; P <.0001). There were no bleeding complications. Median follow-up was 11.3 months (range, 0.8-72.4 mo). Follow-up at 30 days demonstrated 90 of 91 limbs to be patent. Primary patency rates of treated limbs at 1 and 3 years were 81% and 71%, respectively. Primary patency was lost in 17 cases (19.1%); interventions to maintain or restore stent patency were performed in 13 cases (14.6%). Primary assisted limb patency rates at 1 and 3 years were 94% and 90%, respectively; secondary patency rate was 95%. Conclusions: Angioplasty with stent placement for treatment of chronically thrombosed iliofemoral veins is a low-risk procedure with acceptable patency rates for as long as 3 years. The outcomes in patients treated in a quaternary referral center are similar to those reported by other centers.
