International audience. BACKGROUND: Acute popliteal artery occlusion is a frequent clinical entity with a risk of major amputation. Several attitudes are possible and treatment is not standardized. The purpose of this study is to demonstrate safety and effectiveness of intra-arterial thrombolysis in acute popliteal artery occlusion. METHODS: This is a retrospective analysis of a prospective database of patients treated by intra-arterial thrombolysis for acute lower-limb ischemia due to popliteal artery occlusion between 2001 and 2014.The primary endpoint was technical and clinical success. Etiologies and etiologic treatment, amputation-free survival, in-hospital mortality and bleeding complications rates were secondary endpoints. RESULTS: Seventy-one patients, with a mean 6-day-old ischemic time before thrombolysis, were analyzed. Technical and clinical success was 90% and 87% respectively. Etiology was embolic in 33 patients (cardiac n = 14, aortic = 6, unknown = 13) and thrombotic in 38 (atheromatous n = 19, entrapment n= 4, popliteal aneurysm n = 11, Buerger n = 2, thrombophilia n = 1, hyperhomocysteinemia n = 1). Survival and amputation-free survival at 30 days were 97% and 94% respectively. There were no major bleeding complications. CONCLUSIONS: Intra-arterial thrombolysis of acute popliteal artery occlusion is an effective technique which reduces the rate of open surgery. The risk of bleeding complications is very low.
