Color duplex sonography guided stent placement in a stenosis of the superficial femoral artery. A case report.

ABSTRACT

We report the first case of a successful stent placement under color coded ultrasound guidance alone in the superficial femoral artery of a 73-year-old woman suffering from intermittent calf claudication following restenosis after an uncomplicated angioplasty five months previously. Because of a hemodynamically residual stenosis after three attempts at dilatation, a percutaneous transluminal angioplasty and stent insertion were performed under the sole guidance of color coded ultrasound. The intervention was performed without complication and at the six-month follow-up examination, the patient was symptom-free and the stent was morphologically intact and hemodynamically functional. This case shows that successful stent placement under ultrasonic guidance alone, without fluoroscopic control is possible, provided that there is adequate sonographic visualization.
