Percutaneous Transluminal Angioplasty In Treatment Of Infrapopliteal Arteriosclerosis Occlusive Disease (24 Cases Reported)

Objective:To evaluate the short term effect and complications together with therapy and prevention of using PTA in treating infrapopliteal arteriosclerosis occlusive disease,and to summarize the technique and experiences.Methods:From January 2007 to March 2009,24 patients (24 limbs) with infra- popliteal artery occlusive disease were treated by PTA.According to Fontaine staging,5 limbs were in stage II,7 limbs in stage III and 12 limbs in stage IV.Clinical symptoms and ankle-brachial index (ABI) were evaluated before and after the treatment.The effects were compared be- tween different lesion types (stenosis or occlusion) of PTA. The therapy and prevention of complications were also analyzed. SPSS 16.0 statistical software packages is used in data collation and descriptive analysis as a statistical method.Results:1. Of these 24 patients ,the technical success rate was of 83.3%(20 limbs) and the clinical success rate was of 79.2%(19 limbs). 2 patients died because of heart failure and pneumonia .The preoprative ABI was 0.55±0.33 and the postoprative ABI was 0.93±0.19.These were significant differences(p<0.01).2.The effects between different lesion types (stenosis or occlusion) was different. 3.The complications included hematoma, arteriospasm, pseudoaneurysm, vascular wall perforation, contrast medium allergy and so on.4. 18 patients were followed up with an average period of 9 (2-24)months. The signs and symptoms in these patients did not increase or recur during the follow-up periods.Conclusion:1.PTA is the first-line choice in the treatment of infrapopliteal arteriosclerosis occlusive disease,there is a clear short-term efficacy.2.stenosis is more easier to solve than occlusion, therefore we should treat these patients as soon as possible.
