title: Twelve months outcome after percutaneous mechanical thrombectomy for treatment of acute femoropopliteal bypass occlusion.
abstract: Acute and subacute ischemia of the legs in acute and subacute femoropopliteal bypass occlusion is a dramatic situation that endangers the survival of the limbs, depending on the severity of the ischemia. Different therapy options like percutaneous mechanical thrombectomy procedures, which include rotational thrombectomy, have become available in recent years in addition to local lysis and surgical thrombectomy. Rotational thrombectomy with the Straub Rotarex(®) System as an endovascular therapy option has demonstrated promising results leading to amputation-free survival in multiple studies. We recently provided data of 22 patients with acute femoropopliteal bypass occlusion where we examined the feasibility of the Rotarex(®) System in this indication. A technical success rate of 82% was demonstrated. During a follow-up period of 6 months, no reinterventions in these patients had to be performed. We now provide patency rates in 21 patients of our study group after a follow-up period of 12 months. The average ABI after 12 months was 0.80 ± 0.1. One patient showed a hemodynamic restenosis in a Nitinolstent distal to the femoropopliteal bypass which was implanted in the index procedure. No reocclusion of the femoropopliteal bypasses occurred in all patients.
