Abstract:
Objective To evaluate the curative effect of interventional therapy in treating arteriosclerosis obliterans (ASO),and to discuss the related factors that may affect the postoperative recurrence.Methods The clinical data of 137 patients with lower extremity ASO (184 affected limbs in total),who were treated with interventional management during the period from January 2011 to October 2014,were retrospectively analyzed.After the treatment,the patients were followed up for 18 months.The arterial patency was checked up periodically,and the related factors that might induce recurrence were analyzed.Results The technical success rates for diseased iliac artery,femoral popliteal artery and infrapopliteal artery were 97.4％,92.5％ and 88.6％ respectively,while the technical success rates for TASC Ⅱ A,B,C and D type lesions were 97.4％,96.1％,89.7％ and 87.0％ respectively.Follow-up check-ups showed that the arterial patency rate of infrapopliteal artery was lower than that of iliac femoral artery and popliteal artery (P＜0.05),the restenosis rate of TASC Ⅱ C and D type lesions was higher than that of TASC Ⅱ A and B type lesions (P＜0.05).Multivariate Cox regression analysis indicated that diabetes mellitus,smoking and hyperlipidemia were the independent risk factors that could affect postoperative recurrence.Conclusion For the treatment of lower extremity ASO,interventional therapy is safe and effective.The postoperative restenosis rate is related to the location and type of the diseased arteries.Effective control of blood sugar level,smoking cessation and lipid-lowering measures can help reducc thc incidence of postoperative recurrence.
