In seven patients, the Rotarex~S catheter was used in the proximal segment of the crural arteries. Data related to the clinical examination, Doppler sonography, angiography and followup from these patients were further used for analysis.RESULTS Two patients(29%) had thrombotic occlusion of the common femoral artery, and the remaining five exhibited thrombosis of the superficial femoral artery and popliteal artery. Mechanical thrombectomy was performed in all cases using a 6F Rotarex~S catheter. Additional Rotarex~S catheter thrombectomy due to remaining thrombus formation with no reflow was performed in the anterior tibial artery in two of seven cases(29%), in the tibiofibular tract and posterior tibial artery in two of seven cases(29%) and in the tibiofibular tract and fibular artery in the remaining three of seven cases(43%). Ischemic symptoms resolved promptly in all, and none of the patients experienced a procedural complication, such as crural vessel dissection, perforation or thrombus embolization.CONCLUSION Mechanical debulking using the 6F Rotarex~S catheter system may be a safe and effective treatment option in case of thrombotic or thromboembolic occlusion of the proximal and mid-portion of crural arteries.展开更多
