Peripheral arterial occlusive disease complicating asymptomatic carotid stenosis / 中华普通外科杂志

ABSTRACT

Objective To evaluate the incidence of asymptomatic carotid stenosis (ACS) in patients with peripheral arterial occlusive disease (PAOD) who was admitted for revascularization.Methods 229 PAOD patients were evaluated by carotid ultrasound preoperatively and divided into severe ACS group (ACS ≥ 70％) and non severe ACS group (ACS ＜ 70％).The clinical characteristics and associated risk factors of the two groups were analyzed.Results The incidence of severe ACS was 19.7％,age,blood pressure,total cholesterol and fibrinogen levels in severe ACS group were significantly higher than those in non-severe ACS group (P ＜ 0.05),the more severe the symptoms of PAOD are,the higher is the incidence of severe ACS.Age,hypertension and hypercholesterolemia were all predictors of severe ACS.Conclusions The severity of PAOD is positively correlated with the incidence of severe ACS.Age,hypertension and hypercholesterolemia are independent risk factors for severe ACS.
