PURPOSE: To evaluate color duplex ultrasonographic (US) guidance of
percutaneous transluminal angioplasty (PTA) of femoropopliteal artery
stenoses and occlusions. MATERIALS AND METHODS: Twenty-four patients (11
women, 13 men; mean age, 65.0 years) with severe claudication, abnormal
ankle-arm pressure indexes, and lesions in the superficial femoral or
popliteal artery depicted at US underwent balloon PTA with US guidance. US
findings were confirmed before and after PTA by means of intravenous
digital subtraction angiography. RESULTS: All of 22 segmental stenoses and
three of four superficial femoral artery occlusions were successfully
treated (in 23 patients). In three cases, a residual stenosis was detected
after initial PTA, and PTA was repeated with a larger balloon catheter. Of
the 21 patients followed up for 6 months, one had reocclusion and three had
hemodynamically significant restenosis. CONCLUSION: Results of PTA with US
guidance in short stenoses or occlusions of the femoral or popliteal artery
are similar to those of PTA with fluoroscopic control.
