动脉DSA对188例脑中风的病因诊断

Intra-arterial DSA Diagnosis in Stroke(Analysis of 188 Cases)

对经ＣＴ证实的１８８例脑中风患者进行了ＤＳＡ检查，确定病因者１２４例，占全部病例的６６％，主要病因为动脉瘤，动静脉畸形（ＡＶＭ）和烟雾病（Ｍｏｙａｍｏｙａ）。笔者认为，ＤＳＡ对脑中风的病因确诊率与患者的年龄、有无高血压史及出血部位有关。对不能解释的脑叶出血和蛛网膜下腔出血（ＳＡＨ）应提倡作血管造影检查。对基底节－丘脑区高血压脑出血的高龄患者，以不做血管造影检查为宜，而对年轻患者无论有无高血压史，接受血管造影检查仍有诊断意义。

Intra-arterial DSA was performed in 188 cases of stroke diagnosed by CT. Theetiology in 124 cases(66%)was determined including aneurysm, AVM and Moyamoya. As a result of this study,the authors concluded that diagnostic accuracy with DSA in stroke is related to age of pa-tient,history of hypertension and location of hemorrhage. Angiography is suggested for cases with unexplainable lobar hemorrhage and subarachnoid hemorrhage,but is not needed when hemorrhage occurs in the region of basal ganglia and thalamus in elderly patients.However,in younger patients,angiography has diagnostic significance irrespective of the presence or absence of hypertension.
