Correlation between arteriosclerosis obliterans and asymptomatic carotid stenosis / 中华普通外科杂志

ABSTRACT

Objective To evaluate the relationship between asymptomatic carotid stenosis (ACS)and lower limb arteriosclerosis obliterans (ASO).Methods 200 patients with lower extremities arteriosclerosis obliterans who were admitted in our hospital between Oct 2013 and Oct 2015 were retrospectively reviewed.Patients were divided into severe ACS (stenosis ≥ 70％)and moderate ACS (stenosis ＜ 70％).Results Compared with moderate ACS,the severe ACS patients were elder,heavier cigarette-smoker and alcohol drinker,higher hypertriglyceride and fibrinogen level (all P ＜ 0.05).The incidence rate of severe ACS increased as lower limb ASO gets more significant (x2 =28.2,P ＜ 0.05).It also increased with age (x2 =7.78,P ＜ 0.05).Multi-factor logistic regression showed advanced age (OR:1.079,95％ CI:1.055-1.104,P ＜ 0.05) and hypertriglyceride (OR:2.013,95％ CI:1.076-3.325,P ＜ 0.05) were risk factors for severe ACS.Conclusions The incidence of severe ACS increased with the increasing of age and severity of lower limb ASO.Advanced age and hypertriglyceride were potential risk factors for severe ACS.
