Successful percutaneous mechanical thrombectomy of an Impella CP-related femoral artery thrombosis

Aims The aim of this retrospective single-center study was to analyze the immediate results, failures and complications of percutaneous mechanical thrombectomy using the Rotarex catheter in the treatment of peripheral artery occlusion. Methods In this study, we identified a total of 42 patients who underwent mechanical thrombectomy using Rotarex catheter at our institution. Procedural outcomes and complications were evaluated. Results The cohort consisted of 42 patients (31 men and 11 women), aged 32–93 years (median 68 years). The number of external iliac artery occlusion was 5, with common femoral artery 5, superficial femoral artery 28, femoral profound artery 2, popliteal artery 12, and brachial artery 2. The causes of occlusion were thrombosis (29 cases, 69%), embolism (6 cases, 14%), and reocclusion after percutaneous intervention (7 cases, 17%). We achieved primary success in 100% of the patients with mechanical thrombectomy, associated with balloon angioplasty (40/42, 95.2%) and stent deployment (16/42, 38.1%). The median time of the interventional procedure was 145 min. We encountered lower percentage of distal embolization (2.4%) and artery dissection (2.4%) during usage of Rotarex catheter in our cohort. Conclusions Rotarex thrombectomy was a useful tool to recanalize occluded vessels with additional treatment such as balloon angioplasty or stent deployment, with a low rate of failures and complications. And prospective studies in this issue are recommended.

Abstract. Background: The aim of this prospective single-centre study was to analyse the immediate results, failures and complications of percutaneous mechanical thrombectomy using the Rotarex catheter in the treatment of acute and subacute occlusions of peripheral arteries and bypasses, as well as to evaluate long-term outcomes of this method. Patients and methods: Patients with acute (duration of symptoms < 14 days) or subacute (duration of symptoms > 14 days and < 3 months) occlusions of peripheral arteries and bypasses were selected consecutively for treatment. The cohort consisted of 113 patients, aged 18 - 92 years (median 72 years). In all, 128 procedures were performed. Results: Angiographic success was obtained in 120 interventions (93.8 %). Reasons for failures were rethrombosis of a partially recanalised segment in six procedures, and embolism into crural arteries in one intervention - percutaneous aspiration thromboembolectomy (PAT) and/or thrombolysis were ineffective in all these cases. Breakage of the Rotarex catheter happened in one procedure. Embolisation into crural arteries as a transitory complication solvable with PAT and/or thrombolysis occurred in four cases. Rethrombosis was more frequent in bypasses than in native arteries (p = 0.0069), in patients with longer occlusions (p = 0.026) and those with poorer distal runoff (p = 0.048). Embolisation happened more often in patients with a shorter duration of symptoms (p = 0.0001). Clinical success was achieved in 82.5 %. Major amputation was performed in 10 % of cases. Cumulative patency rates were 75 % after one month, 71 % after six months, 38 % after 12 months, 33 % after 18 months and 30 % after 24, 30, 36 and 42 months. Conclusions: Rotarex thrombectomy has excellent immediate results with a low rate of failures and complications. In comparison to thrombolysis, it enables the fast and efficient treatment of acute and subacute occlusions of peripheral arteries in one session.
