Abstract
PURPOSE: To report technical success, outcomes, and patency of iliocaval stent reconstruction for inferior vena cava (IVC) filter-bearing iliocaval thrombosis. MATERIALS AND METHODS: A total of 120 patients with 123 IVC filters and symptomatic iliocaval thrombosis underwent stent reconstruction. Mean patient age was 55 years (range, 19-88 y). Filters included 70 (57%) retrievable and 53 (43%) permanent filters. Symptoms included lower extremity swelling or pain (n = 93), ulcers (n = 8), phlegmasia (n = 7), back pain (n = 5), shortness of breath (n = 4), worsening renal function (n = 2), and stenosis identified during translumbar catheter placement (n = 1). Clinical success was defined as decrease in clinical, etiology, anatomy, and pathophysiology (CEAP) score of at least 1; resolution of presenting symptoms; or normalization of renal function in patients with juxtarenal or suprarenal thrombosis on presentation. Technical aspects of reconstruction, technical success, complications, 6-month clinical response, and 6-, 12-, and 24-month primary, primary-assisted, and secondary stent patency rates were recorded. RESULTS: Stent reconstruction was technically successful in all 120 patients, 63 of whom (53%) underwent thrombolysis. Thirty filters (24%) were retrieved, and 93 (76%) were excluded with stent placement across the indwelling filter. Six minor and 2 major complications occurred. Clinical success was achieved in 115 patients (96%) at 6 months. Six-, 12-, and 24-month primary iliocaval stent patency rates were 96.4%, 94.8%, and 87.2%, respectively. Twenty-four month primary-assisted and secondary patency rates were 90.3% and 94.2%, respectively. CONCLUSIONS: Iliocaval stent reconstruction is an effective treatment for filter-associated thrombosis with 100% technical success and 96% clinical success at 6 months. Technical and clinical outcomes in patients who underwent filter retrieval versus filter exclusion were similar.
