Objective To assess the technical feasibility, patency and outcomes of subintimal angioplasty (SIA) for treatment of the lower extremity arteriosclerosis occlusions. Methods During the period from December 2003 to August 2008, 122 lower extremities with arteriosclerosis occlusions (median length, 10.25 cm;range, 4.5 to 28 cm) were treated on an intention-to-cure basis with SIA. Twenty-three lower extremities had disabling claudication and ninety-nine had limb-threatening ischemia. Patient history, demographics, procedural details, complications, and follow-up information were collected and analyzed. Patency, limb salvage, sustained improvement in claudication was determined by Kaplan-Meier analysis. Results The technical success rate of SIA was 83%. Following successful SIA, the mean ankle-brachial index increased from 0.19±0.11 to 0.67±0.29 (P<0.01). Primary patency at 12 and 24 months was 54%±5% and 45%±4% respectively, the clinical effective rates (rates of limb salvage and improvement in claudication) at 12 and 24 months were 82%±5% and 79%±4% respectively. No serious complications occurred. Conclusion In a selected group of patients, SIA is feasible with a high technical success rate and the clinical effective rates are satisfactory, there were no severe complications. SIA is a good treatment alternative in patients suffering from chronic ischemia with arteriosclerosis occlusions in the lower extremity.

Objective The purpose of this study was to assess the technical feasibility, safety and effectiveness of percutaneous transluminal angioplasty (PTA)for the treatment of severe limb ischemia caused by tibioperoneal arteries occlusion. Methods From June 2004 to May 2007,35 patients with critical limb ischemia (CLI)were treated on an intention-to-treat basis with tibioperoneal arterial PTA. Main outcome measures were technical success rate, primary patency rate, limb salvage rate and complications. Results The technical success rate of tibioperoneal arterial PTA Was 83%.Mean follow-up time was 11.5 months, primary patency rate and limb salvage rate were 57%and 82%,respectively.Mean length of tibioperoneal arterial PTA was 9.5 cm(4.5～14 cm),concurrent treatment of iliac artery or femoral-popliteal artery was carried out in 19 patients via either angioplasty or combined with stenting.There were three complications including arterial spasm and thrombosis in one, which Was relieved by thrombolysis and antispasmodics, and artery perforation in 2 cases, which was treated conservatively. Conclusion In tibioperoneal arterial occlusions in CLI patients, PTA is feasible with a high initial technical success rate and high limb salrage rate,tibioperoneal arterial PTA carries a lower morbidity and less severe complications. PTA is a safe, effective and good treatment alternative for CLI patients of tibioperoneal arterial occlusions.
