Abstract:
Objective To study the cerebral vascular anomalies in patients with posterior circulation infarction and their risk factors.Methods The clinical data of 337 consecutive patients with first-onset of posterior circulation infarction,extracted from Nanjing Stroke Registry Program from January 2007 to June 2010,were collected.Computerized tomography angiography(CTA),magnetic resonance imaging angiography(MRA)and digital subtraction angiography(DSA)were performed in all the patients to clarify the site of vascular anomalies and their mechanisms; and their relation with their risk factors were analyzed.Results One hundred and ninety-five patients with posterior circulation infarction(57.9％)had vascular anomalies with 394 lesions.There were 115 lesions in the ostial vertebral artery,81 lesions in the V4 of vertebral artery,49 lesions in the basilar artery and 47 lesions in the posterior cerebral artery.Hypertension(64.9％)was the most common risk factors in patients with posterior circulation infarction smoking,followed by diabetes mellitus,drinking,and hyperhomocysteinemia.In patients with vascular anomalies,patients with hypertension enjoyed significantly higher incidence of vascular anomalies than those without hypertension,while those with cardiac disease were not(P＜0.05).Conclusion The incidence of posterior circular anomalies in patients with posterior circulation infarction is high,especially in the patients with hypertension and diabetes mellitus.
