To evaluate color duplex ultrasonographic (US) guidance of percutaneous transluminal angioplasty (PTA) of femoropopliteal artery stenoses and occlusions.
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.
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.
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.
评估彩色双功能超声（US）引导下对股腘动脉狭窄和闭塞进行经皮腔内血管成形术（PTA）的效果。
24例患者（11名女性，13名男性；平均年龄65.0岁），有严重间歇性跛行、踝臂压力指数异常，超声显示股浅动脉或腘动脉有病变，在超声引导下接受了球囊PTA治疗。PTA前后的超声检查结果通过静脉数字减影血管造影得以证实。
22处节段性狭窄中的所有病例以及4处股浅动脉闭塞中的3处成功得到治疗（23例患者）。3例患者在初次PTA后检测到残余狭窄，使用更大的球囊导管再次进行PTA。在随访6个月的21例患者中，1例发生再闭塞，3例出现血流动力学显著的再狭窄。
超声引导下对股动脉或腘动脉短段狭窄或闭塞进行PTA的结果与透视引导下PTA的结果相似。
