A 79-year-old man with a history of atrial fibrillation presented for evaluation of sudden onset of intermittent claudication of the left lower limb. An angiogram revealed thrombotic total occlusion of the left superficial femoral artery (SFA). A 10-Fr sheath was antegradely inserted into the left common femoral artery (CFA), and the guidewire penetrated the lesion. Thromboaspiration using an 8-Fr long sheath inserted into a 10-Fr short sheath was performed repeatedly. Intravenous anticoagulant was administrated immediately after endovascular treatment. Follow-up angiography performed 12 days after the procedure confirmed the absence of residual thrombus in the SFA. Thromboaspiration using a large-diameter catheter is a feasible, cost-effective strategy for treatment of acute and subacute limb ischemia.
