Selection And Prognosis Comparison Of Balloon Expansion Combined With Stent Implantation And Drug Application Of Balloon Expansion In The Treatment Of Femoral Popliteal Arteriosclerosis Occlusion

Objective:Arteriosclerosis obliterans(arteriosclerosis obliterans,aso)of lower extremity is a common disease and frequent disease,which mainly refers to arteriosclerosis involving large and medium arterial vessels of lower extremity.Atherosclerosis substances continue to expand and secondary thrombosis,which can cause stenosis and occlusion of arterial wall and make limbs appear chronic or acute ischemia and other symptoms.Its pathogenesis is more complex,and the prognosis of the disease is poor,high mortality,clinical treatment is difficult,at the same time,the daily life and quality of life of patients also have a greater impact,so it has been widely concerned by all walks of life,is the focus of vascular surgery research.Femoral popliteal artery arteriosclerosis obliterans have a strong representative of their high incidence in lower extremity arteriosclerosis obliterans.The treatment of the disease has developed from the initial era of endarterectomy and open bypass surgery to the new era of endovascular repair.The drug-coated balloon(dcb)then further reduces the risk of stent restenosis.The purpose of this study was to compare the efficacy of balloon dilatation combined with stent implantation and drug-coated balloon in the treatment of femoral and popliteal artery arteriosclerosis obliterans.Methods: The 50 patients treated with femoral-popliteal artery occlusion from June2018 to December 2019 were selected as the subjects of the study to analyze the relevant characteristics of the disease,including the treatment methods,clinical symptoms and signs before and after surgery,and were divided into dcb group and joint treatment groups according to the interventional methods,and 25 patients in the two groups.The long-term lumen loss rate(late lumen loss,lll),ankle and brachius index(ankle brachial index,abi),and rutherford classification were compared in 6months and 12 months before and after the surgery.Observe and compare the interim treatment and prognosis.Results:After treatment,both 6 and 12 months performed superior lll in dcb,p< 0.05.vascular patency was 88%,80% in dcb group and 76% and 72% in dcb group were statistically significant(p< 0.05).Patients were significantly higher compared with preoperative abi(p< 0.05).In inter-group comparison,abi at 6 and 12 months after dcb patients were significantly higher than in the combined therapy group,and the differences were statistically significant(p< 0.05).No statistical difference in rutherford classification com parison between the two groups(p> 0.05).Conclusions:DCB has a more obvious effect in intermediate vascular patency rate and abi recovery.2.drug-coated balloon treatment for femoral-popliteal segment aso prognosis is superior to balloon expansion combined with stent implantation and can be considered under the strict grasp of surgical indications.
