Mechanical thrombectomy in patients with deep venous thrombosis

Purpose: To report our experience with mechanical thrombectomy in proximal deep vein thrombosis (DVT). Methods: Eighteen patients with a mean (+/- SD) age of 37.6 +/- 16.1 years who presented with DVT in the iliac and femoral vein (n = 3), inferior vena cava (n = 5), or inferior vena cava and iliac vein (n = 10), were treated with the Amplatz Thrombectomy Device after insertion of a temporary caval f ilter. Results: Successful recanalization was achieved in 15 of 18 patients (83%). Overall, the percentage of thrombus removed was 66 +/- 29%: 73 +/- 30% at caval level and 55 +/- 36% at iliofemoral level. Complementary intervention s (seven patients) were balloon angioplasty (n = 2), angioplasty and stenti ng (n = 2), thrombo-aspiration alone (n = 1), thrombo-aspiration, balloon a ngioplasty, and permanent filter (n = 1), and permanent filter alone (n = 1 ). There was one in-hospital death. Follow-up was obtained at a mean of 29. 6 months; three patients had died (two cancers, one myocardial infarction); 10 had no or minimal sequelae; one had post-phlebitic limb. Conclusion: Mechanical thrombectomy is a potential therapeutic option in pa tients presenting with proximal DVT.
