The patient was an 88-year-old woman who had been experiencing intermittent claudication of the right lower limb for several months. The right and left ankle brachial index (ABI) were 0.61 and, 1.12, respectively, with the right being predominantly decreased. Lower limb angiography revealed severe stenosis and calcification of the right common femoral artery (CFA). Exercise therapy was performed from about three weeks, however, the improvement was insufficient. To further improve the condition, after two weeks, cavitron ultrasonic surgical aspirator (CUSA) was used to remove the right common femoral carcification, and angioplasty with a bovine pericardial patch was performed to prevent restenosis. Postoperatively the ABI at rest normalized, and intermittent claudication did not occur. Postoperatively computed-tomography angiography showed that calcification of the right CFA had disappeared and stenosis had improved. There was no difference between the left and right ABI, and three-dimensional (3D) QFlow imaging showed a significant improvement in the popliteal artery blood flow to 12.65 mL/s. In Japan there have been no previous reports of angioplasty using a bovine pericardial patch after endarterectomy with CUSA. Here, we report a case in which improvement in blood flow was confirmed multilaterally using images and numerical values.
