Abstract:
ObjectiveTo explore the methods and effectiveness of interventional revascularization of complex arteriosclerosis obliterans (ASO)of lower extremity arteries according to their imaging characteristics.Methods Seventy-eight patients with lower extremity ASO complex lesions classified as TASC Ⅱ C/D ( n =68 ) and TASC Ⅱ B ( n =10) underwent antigrade or combined antigrade-retrograde subintimal angioplasty.Their clinical situations were Fontaine stage Ⅲ/Ⅳ or severe stage Ⅱ.All the long occlusion,flush occlusion,multiple occlusion,popliteal artery occlusion,below knee artery occlusion and aortoiliac artery occlusion were identified as complex lesion imaging features and as the indication of interventional treatment if only there were visible outflow vessels and suitable puncture site.Statistical analysis was used to compare ankle-brachial index (ABI) pretreatment and post-treatment by t test.Results Successful revascularization was achieved in 73 patients technically.No obvious complications occurred.Ischemia symptoms improved quickly after accomplishment of recanalization.Average ABI increased from 0.45 ±0.07 to 0.76 ±0.11 after the treatment(t =- 19.78,P ＜0.01 ).Symptoms in 5 patients who failed to get arterial recanalization were stable.Follow up of 6 to 12 months in 47 patients showed stable improvement in 22 of them.Conclusion It is more practical to choose and expand application of interventional treatment for complex ASO according to imaging characteristics of lesions than according to TASC classification.
