Revascularization of lower limb artery ischemia for elder patients / 中华普通外科杂志

ABSTRACT

Objective To evaluate the result of revascularization for lower limb artery ischemia in elder patients. Method During Jan 2006 to Nov 2008, 262 elder patients (60 years old and up), underwent artery revascularization for lower limb arterial ischemia. Mortality, morbidity, primary patency, secondary patency and limb salvage were analyzed. Result There were a total of 323 ischemia limbs in those 262 elder patients undergoing revascalarization, among those 102 limbs underwent artery bypass, 98 limbs underwent endoluminal angioplasty with or without stenting, 67 limbs underwent embolectomy or endarterectomy, 56 limbs underwent open surgery combined with endoluminal treatment due to multiple segment lesions. Operation success rate was 94.7%. Two patients died within 30 days. Perioperative morbidity developed in 15 cases. 245 patients (93.5%) were followed-up from 1 month to 35 months. Mortality was 6.1% (15 cases), primary patency was 80.5%, secondary patency was 92.7% and limb salvage rate was 95.2%. Risk factors analysis showed that history of cardiac disease and elder ages were associated with higher mortality. Diabetes mellitus, critical ischemia and multiple segment lesions were associated with poor long term patency and limb salvage. Conclusion Lower limb ischemia is severe disease related to elder patients' death and amputation. Careful patient selection, detailed pre-operation work-up, meticulous operative technique play crucial roles for a successful arterial reconstruction.
