Retrospective Clinical Observation Of Bypass Surgery And Endovascular Therapy To Femoral-popliteal Arteries In Arteriosclerosis Obliterans

Objective: Generally speaking, the most important methods of curingarteriosclerosis obliterans are bypass surgery and endovascular therapy. Eventhough the surgeons usually choose bypass surgery to remedy the patients whoare classified to be the rank C or D of the TASC-II, a few doctors would like totry endovascular therapy and get some desired results. The writer of this articlewants to observe, analyze, compare the clinical curative effect of the twosurgical techniques through the retrospective analysis, furthermore, providedetail and reliable basic reference to the clinical treatment and the choice ofoperation for femoral-popliteal artery in arteriosclerosis obliterans.Methods: According to the inclusion criteria and the difference of surgicaltechnique, the122patients (140limbs) who had been classified to grade C or Dof TASC-II in the first hospital of Jilin university during2009.2to2012.12aredivided into two groups. The bypass surgery group contains75cases, and theendovascular therapy group contains47cases. The researchers determinate thepreoperative and postoperative ankle/brachial index, estimate the postoperativeevaluation of clinical symptoms and the risks of complications, record thelength of time after the operations, and follow up the patency rates of thepatients. Then the researchers analyze and compare the postoperative generalconditions of the patients, clinical symptoms, the changes of the preoperativeand postoperative ankle/brachial index, and the patency rates of the patientsthrough the t test and chi-square analysis.Results: The statistical analysis shows that both of the two operative techniques are significantly effective to the patients of grade C or D of TASC-II.The ankle/brachial index are improved significantly. The symptoms areobviously relieved. The patients of the endovascular therapy group are in arelatively short period (the average is7.32±1.80). There is no difference in theshort-term patency rate (<2years) of the patients between the bypass surgerygroup and the endovascular therapy group. At the same time, the long-termpatency rate (≥2years) is much better than that of the latter. The patency ratesof24months and30months are85.4%and81.2%.Conclusion:1. We can obtain a desirable treatment from both of bypasssurgery or endovascular therapy, and there is no significant difference in theefficacy;2. The patients of the endovascular therapy group are in a relativelyshort period, and have less complications;3. There is no difference in theshort-term patency rate (<2years) of the patients between the bypass surgerygroup and the endovascular therapy group. But the long-term patency rate (≥2years) is much better than that of the latter.
