The Short-Term Effect Of Simple PTA Versus PTA Combined With Stent Placement In Tre Ating Femoral-Poplitenl Artery Occlusive Disease

Objective:To compare the short-term clinical effect of simple balloon angioplasty(PTA) and PTA combined with stent placement(PTAS) in trea ting femoral-popliteal artery occlusive disease, and to investigate the reaso nable endovascular treatment strategy in femoral-popliteal artery occlusive disease.Methods:A retrospective analysis of 41 patients (38males and 4femal es) of 42 limbs, between the ages of 45-86 years, mean age 69.8 years, with femoral-popliteal artery occlusion, hospitalized during December 2012 to December 2014 at the First Affiliated Hospital of Guangxi Medical U niversity, Department of Vascular Surgery. Simple balloon dilatation (PTA) group (25 patients) and PTA combined with stent placement(PTAS) grou p(16 patients with 17 limbs) are divided according to treatment. The simul taneous treatment of occlusion of common iliac artery, external iliac artery and arteries inferior to the knee. Clinical symptoms, ABI, limbs salvage rate s and other data were recorded on 1 week,1 month,6 months,12 months resp ectively after operation and were statistically analyzed.Results:41 patients (42 limbs), technical success rate was 90.5% (38/ 42). Perioperative mortality was 2.4%(1/41). The main complication rate was 9.5% (4/42). In the two-group, pain symptoms and ABI,1 week afte r operation, was improved after treatment, comparison within each group difference was statistically significant (P<0.05), comparison between the t wo groups showed no statistical difference (P>0.05). After 1 month,6 m onths and 12 months, PTA group and PTAS group patency rates were 83. 3%,100%; 65.0%,78.6%;43.8%,54.5% respectively, limb salvage rate w ere 95.8%,100%; 85.0%,100%;78.6% and 100% respectively, survival ra tes were 96.0%,100%; 79.2%,92.9%; 68.4%,88.9%, respectively. Durin g follow-up period of two groups, comparison of the patency, limb salvag e and survival rates were not statistically significant(P>0.05). While comp arison of the hospital costs was statistically significant(P<0.05).Conclusion:Both PTA and PTAS had the similar short-term efficacy in treating femoral-popliteal arteriosclerosis obliterans, and the long-term efficacy to be studied. The treatment costs of PTA was lower than that o f PTAS.
