Endovascular Treatment Of Arteriosclerosis Obliterans Of Lower Extremities

Background:Arteriosclerosis obliterans cause chronic lower limb chronic ischemia because of stenosis and occlusion of the lower limb artery. The mobidity increased with the aging population gradually increased. arteriosclerosis obliterans cause high disability rate in the end. Traditional surgical methods have high complication rate and mortality. Endovascular treatment have characteristics of minimally invasive, can be repeated operation, and lower mortality and complication rates, endovascular treatment used more and more in clinical, with good prospects for development.ObjectiveDiscussion and analysis of lower limb ischemic disease of endovascular therapy. And improve therapeutic effect of Peripheral arterial disease.MethodsWe conducted a retrospective analysis on 16 Patients of atherosclerotic occlusive disease with clinical data. Underwent endovascular treatment from June 2005 to June 2007 in the Qianfoshan Hospital of Shandong University.14 male and 2 female Patients, a mean age of 62.4 years(range 51-85 years). According to the Foniaines tages, there were 2 stage lla Patients,12 stage l1b Patients,1 stage 111 patient(rest pain),1 stage IV patient(Foot ulcer). According to TASCII classification, there were 2 type A Patients,9 type B Patients,3 type C Patients,2 type D Patients. Preoperative ankle-brachial index (ABI) check between 0-0.86, with an average of 0.43. CTA Show: iliac artery stenosis in 6 cases, femoral artery occlusion inl case, and femoral artery stenosis inl; superficial femoral artery stenosis in 6 cases, occlusion in 3 cases,1 patient had bilateral stenosis; segmental occlusion below knee artery in 1 case.A total of 19 lesions to be treatmented, one lesion not to be opened,19 lesions underwent balloon dilatation and 8 lesions were performed balloon dilatation and stent placement.ResultsIn the iliac artery, the acute patency rate and technical success rate was 100%.The 1-and 2-year Patency was 83.3%,83.3%.In the femoralpopliteal artery,the acute patency rate was 91.7%, technical success rate was 100%, the Patency at 1 and 2 year were 81.8% and 72.7%, Below-knee artery occlusion in 1 case, Ulcers gradually healed after treatmented.Anklebrachial index of postoperation Increased more than o.15.ConclusionsEndovascular treatment for iliac arterial occlusived disease can be used as the first choice because of Satisfactory short-term and long-term outcome;The endovascular treatment can be use as first choice for high-risk patiens for femoral arterial occlusive disease;Endovascular treatment is prefered in patients with belowe-knee artery occlusion.
