目的研究颈内动脉系统狭窄或闭塞急性脑梗死患者侧枝代偿情况。方法回顾性分析经全脑数字减影血管造影(DSA)证实存在颈内动脉(ICA)狭窄或闭塞45例急性脑梗死患者,临床分为ICA重度狭窄组、ICA闭塞组,分析两组急性脑梗死患者Willis环初级及次级代偿情况。结果 45例患者中,狭窄组17例,闭塞组28例,侧枝代偿发生率为80.0%(36/45),其中初级Willis环合并次级代偿发生率为60.0%(27/45),Willis环前交通开放率为24.4%(11/45),后交通开放率为26.7%(12/45),次级代偿眼动脉代偿发生率40.0%(18/45),软脑膜支代偿发生率为40.0%(18/45)。结论 ICA重度狭窄或闭塞急性脑梗死患者侧枝代偿方式以初级Willis环合并次级代偿为主,眼动脉开放在ICA闭塞急性脑梗死患者较常见。
Objective To study the collateral compensations of patients with stenosis or occlusion of acute cerebral infarction in the internal carotid artery. Methods A retrospective analysis of 45 patients with acute cerebral infarction confirmed by global digital subtraction angiography (DSA) of stenosis or occlusion of internal carotid artery (ICA) was divided into two groups: acute severe brain infarction (ICA) and severe acute cerebral infarction Willis ring primary and secondary compensatory status in infarcted patients. Results Among the 45 patients, 17 cases were in the stenosis group and 28 cases in the occlusion group. The incidence of collaterals compensation was 80.0% (36/45), of which 60.0% (27/45) The open traffic of Willis Ring Road was 24.4% (11/45), the open traffic rate was 26.7% (12/45), the compensatory rate of secondary compensatory ophthalmic artery was 40.0% (18/45) Reimbursement rate was 40.0% (18/45). Conclusions The patients with ICA severe stenosis or occlusion of acute cerebral infarction were compensated mainly by primary Willis ring with secondary compensation. Open ophthalmic artery was more common in ICA occlusion patients with acute cerebral infarction.
