Hybrid operation for the treatment of multifocal lesions in arteriosclerosis obliterans of the lower extremity / 中华普通外科杂志

ABSTRACT

ObjectiveTo evaluate hybrid operation for arteriosclerosis obliterans (ASO) of the lower extremity.MethodsClinical data of 35 ischemic limbs in 32 ASO cases receiving hybrid operation from May,2007 to August,2009 were retrospectively analysed.The indications,clinical result,complications,perioperative mortality,vascular patency rate and limb salvage rate was evaluated.ResultsThirty-five ischemic limbs in 32 cases underwent hybrid operation. Procedures were successful in 94％ cases (33/35). The average postoperative ABI significantly increased from 0.49 ±0. 18 to 1.06 ± 0. 17 ( one day after surgery) or 0. 96 ± 0. 16 ( six months after therapy). One patient suffered limb amputation due to surgical failure, one case was complicated with cerebral infarction and the operation was terminated. No patient died in perioperative period. Twenty-six cases (28 ischemia limbs) were followed-up from 2 month to 28 months, the follow-up rate was 87％ (26/30). Vascular patency rate in 6 months after operation was 93％ (26/28), and limb salvage rate was 96％ (27/28). Two cases suffered from below-knee reocclusion 5 -6 months after therapy, and one of these two cases needed a limb amputation.ConclusionHybrid operation is the therapy of choice for multifocal lesions in arteriosclerosis obliterans of the lower extremities with a low risk and higher patency in short term.
