大脑中动脉狭窄相关的脑梗塞20例临床分析

Clinical analysis on 20 cases of Cerebral Infarcts Related to Middle Cerebral Artery Stenosis

目的：分析20例大脑中动脉（NICA）狭窄相关的脑梗塞患者的临床中风模式与神经影像（CT／MRI）特点。方法：对经颅多普勒超声（TCI））等确诊的20例MCA狭窄的脑梗塞患者进行临床与神经影像的对比分析。结果：20例中．腔隙综合征10例（50％），CT／MRI显示无病灶2例（10％），基底节和内囊腔隙性脑梗塞8例（40％）；非腔隙综合征10例（50％），CT／MRI显示MCA皮层支梗塞9例（45％），其中合并基底节和内囊腔隙性脑梗塞及大灶梗塞各3例（15％），另1例（5％）为MCA主干梗塞。结论：MCA狭窄与MCA分布区皮质、皮质下、基底节和内囊单独或联合梗塞有关。90％（18／20）患者临床综合征与神经影像结果相符。

OBJECTIVE: To analyse clinical stroke patterns and neuroimaging (CT/MRI ) charac teristics for 20 cases of cerebral infarcts with middle cerebral artery (MCA ) stenosis. METHODS:20 patients with cerebral Infarcts whos(: MCA stenosis was dlagnosed by transcranial Doppler sonography (TCD) etc. , were analysed With comparision of clinical features and their neuroimag ing characteristics. RESULTS: Of these 20 patients, 10 Patients (50 % ) had lacunar syndromes,CT or MRI scans showed no lesion in 2 patlents (10% ) .and lacunar infarcts of the basal ganglia and internal capsular were disclosed in 8 patients (40% ); 10 Patients (50% ) had nonlacunar syn dromes,CT or MRI scans showed cortical MCA branch infarcts were present in 9 patients (45 % ),of these 9 patients,3(15% ) in comblnation with the basal ganglia and internal capsular lacunar in farcts and large infarcts respectively, and 1 patients (5 % ) addltional had a large MCA trunk in farcts. CONCLUSLON: MCA stenosis was assoclated with cortical, subcortical, the basal ganglia and intermal capsular MCA branch infarcts alone or combination. In 18 of the 2O patients (90%) the clinical syndromes corresponded to the nuoroimaging findings.
