[Percutaneous transluminal angioplasty using Filtrap to capture thrombus for chronic total occlusion of superficial femoral artery: a case report].

A 75-year-old female was admitted for cerebral infarction and arteriosclerosis obliterans. Computed tomography with contrast medium revealed occlusion of the superficial femoral artery (SFA). Percutaneous transluminal angioplasty (PTA)was performed for the SFA (length 30 cm), but massive thrombus was seen in the SFA.
