Long term clinical and angiographic outcome following percutaneous transluminal angioplasty and stent placement for iliac artery stenosis / 介入放射学杂志

ABSTRACT

Objective This study reports the early and late results of percutaneous transluminal angioplasty (PTA) and intravascular stenting for atherosclerotic stenosis of the iliac artery. Methods From December 1994 to February 2000, we performed iliac artery angioplasty and primary intravascular stent placement in 42 vessel of 31 patients (23 men and 8 women; mean age, 70.5 years). A total of 44 self expanding Wallstents ( Boston Schneider, Inc. ) were deployed. All patients underwent angioplasty and stent placement successfully. Results Clinical follow up was available for all patients at a mean of (36?13) months. All patients with clinical ischemic category (claudication or rest pain) were improved. Angiographic follow up with completed data are available for 20 of 31 patients at a mean follow up of (10?5) months. The iliac artery restenosis rate was 2%(1/42). The patients again underwent balloon angioplasty successfully. Conclusions PTA and primary stenting of the iliac arteries are effective and safety for treating iliac arterial stenosis,and should be the method of first shoice.
