Abstract/OtherAbstract:
OBJECTIVE: This study investigated the safety and effectiveness of the infrainguinal use of the AngioJet rheolytic mechanical thrombectomy system (Possis Medical, Minneapolis, Minn) for the treatment of acute infrainguinal thromboembolism occurring during lower limb revascularization procedures. METHODS: For the interval between January 2000 and January 2011, our hospital's database was meticulously searched for all patients with acute thromboembolism that occurred during lower limb angioplasty, with or without stenting procedures, who were treated with infrainguinal AngioJet thrombectomy. Baseline patient demographics and procedural details were analyzed. Primary end points included technical success, defined as the complete revascularization of the acutely occluded vessel, clinical success, defined as the absence of death or amputation ≤60 days, and procedure-related complication. Secondary end points included embolized vessel primary patency and overall patient survival. RESULTS: During this 12-year period, 3147 peripheral percutaneous procedures of angioplasty, with or without stenting, were performed in our department. Intraoperative, clinically, and angiographically evident thromboembolism occurred in 18 of 3147 procedures (0.57%), and 14 (77.7%) were managed using the AngioJet thrombectomy system. In total, 22 arteries were treated (13 infrapopliteal, 3 femoropopliteal, and 6 popliteal arteries). All patients had a completion angiogram for the assessment of the runoff vessels status. Technical and clinical success occurred in 13 of 14 (92.8%). Adjunctive local thrombolysis or clot trapping, or both, with stenting was used in 64.3% and 42.8% of the procedures, respectively. Mean time follow-up was 38.1 ± 49.0 months. The 1-year embolized vessel primary patency rate was 50.9%, and the survival rate was 53.5% up to 11.5 years of follow-up, as estimated by Kaplan-Meier analysis. The 1-year limb salvage rate was 92.3%. There were no procedure-related minor amputations and one (7.1%) procedure-related major above knee amputation. CONCLUSIONS: The use of AngioJet rheolytic thrombectomy and adjunctive local thrombolysis or stenting, or both, under filter protection, is safe and effective for the management of severe thromboembolic complications occurring in the femoropopliteal and infrapopliteal arteries during peripheral endovascular procedures.
