The Clinical Effect And Complication Of The Iliac-deep Femoral Artery Angioplasty For The Treatment Of Lower Extremity Arteriosclerosis Obliterans

lower extremity arteriosclerosis obliterans (LEASO)，as a commondisease in vascular surgery, is a ischemic disease which is caused byatherosclerosis. Many methods are used to LEASO, but allshortcomings,as conventional treatment efficacy is not ideal, surgicaltreatment with big trauma, more complications and postoperativerestenosis problems. Endovascular treatment with less trauma, relativelyhigh repeatability rate, higher security and fewer complications，is ofgreat value and is becoming the first choice of the treatment of LEASO.Objective: To explore the clinical effect of the iliac—deep femoral arteryangioplasty for the treatment of LEASO.Method:87cases with LEASO were selected according to methodsof treatment, Male53cases, female34cases, with an average age of80.40±4.6years old.32cases set to group A with iliac artery occlusiveand femoral artery stenosis or occlusion were treated with balloondilatation and stent implantation, set to group A.27cases set to group Bunderwent iliac artery balloon angioplasty and stent implantation longsegment femoral artery occlusion untreated.28cases set as group C aretreated with routine drug treatment. As there is no outflow of distal limb. Analysis of the change of clinical symptoms, ABI values before and afterthe treatment, claudication distance, limb salvage rate and postoperativecomplications and related index were analyzed.Results: Rutherford grading after treatment of patients is improvedcompared to that before treatment, The clinical symplones, ABIvalues,and claudication distance, limb salvage rate of group A and groupB are better than that of group C after24months follow-up. The ABIvalues change and claudication distance of group A are better than that ofgroup B, but the limb salvage rate has no obvious difference.Perioperative complications of group B is lower than that of group A.Conclusion: Iliac—deep femoral artery angioplasty can effectivelyimprove the symptoms of lower limb ischemia, decrease the amputationrate, significantly shorten the operation time, reduce the operation risk,increase the success rate of surgery. Especially for patients who are ofhigh age, bad health state and bad outflow way. At the same time, it canshorten the course of treatment and reduce the operation cost.
