摘要
目的分析急性后循环多发与单发脑梗死的病因差异。方法选择后循环急性脑梗死患者71例,根据磁共振弥散加权成像(DWI)病灶特点分为多发组和单发组,按TOAST分型标准对卒中病因进行分类。结果 28例多发脑梗死中大动脉粥样硬化性卒中19例,心源性栓塞4例,小动脉闭塞性卒中2例,其他原因所致缺血性脑卒中1例,不明原因的缺血性脑卒中2例;43例单发脑梗死中大动脉粥样硬化性卒中10例,心源性栓塞4例,小动脉闭塞性卒中25例,其他原因所致缺血性脑卒中2例,不明原因的缺血性脑卒中2例。多发组与单发组相比,多发组大动脉粥样硬化性卒中更常见(P=0.000),单发组小动脉闭塞性卒中更常见(P=0.000)。结论急性后循环多发脑梗死的主要病因是大动脉粥样硬化性卒中,单发脑梗死的主要病因是小动脉闭塞性卒中。
Objective To evaluate the stroke etiology between acute multiple brain infarction （AMBI） and acute single brain infarction（ASBI） in the posterior circulation. Methods The diffusion weighted imaging （DWI）data of 71 patients with acute cerebral infarction in the posterior circulation were assessed. The patients were divided into AMBI group and ASBI group according to the lesion patterns on DWI. The stroke etiological subtypes were determined by the criteria of the Trial of Org 10 172 in Acute Stroke Treatment（TOAST）. Results There were 28 AMBI patients,43 ASBI patients. In AMBI group, there were 19 patients with largeartery atherosclerotic cerebral infarction, 4 with cardio embolism, 2 with small-artery occlusion, 1 with stroke of other determined etiologies, and 2 with stroke of undetermined etiologies. In ASBI group, there were 10 patients with large-artery atherosclerotic cerebral infarction, 4 with cardio embolism, 25 with small-artery occlusion, 2 with stroke of other determined etiologies, and 2 with stroke of undetermined etiologies. The most frequent cause of stroke was large-artery atherosclerosis in AMBI group （ P = 0. 000 ）, and small-artery occlusion in ASBI group（P = 0.000）. Conclusions This study shows that the main cause of AMBI and ASBI in the posterior circulation is large-artery atherosclerosis and small-artery occlusion respectively.
