中青年卒中的DSA检查及病因分析

目的　探讨中青年卒中的病因及数字减影血管造影 (DSA)对病因诊断的价值。方法　对 1992～ 2 0 0 3年经头颅CT、MRI、脑脊液检查证实的 96例中青年卒中的DSA检查病因进行回顾性分析。结果　 96例中DSA检查总阳性率 78.1% ,在 64例出血性卒中中 ,脑动脉瘤占 42 .2 1% ( 2 7/ 64 ) ,动静脉畸形 14 .0 6( 9/ 64 ) ,Moya -Moya7.81% ( 5 / 64 ) ,三者共占 64 .0 % ( 4 1/ 64 )。 结论　中青年卒中主要病因是脑动脉瘤、AVM ,尤多见于出血性卒中。DSA对其大部分能明确病因。

DSA Examination and Etiological Investigation in Middle Aged and Young Patients With Stroke

Objectives To investigate the etiology of middle aged and young patients with stroke, and the diagnostic value of digital subtraction angiography (DSA) in middle aged and young patients with stroke. Methods The DSA examination data of 96 patients, who were confirmed as stroke by CT, MRI and examination of CSF, was analyzed retrospectively .Results Positive rate of DSA examination was 71.8%. In 96 patients with stroke, 64 patients were caused by cerebral hemorrhage. Among 64 patients, cerebral aneurysm was 42.21%(27/64), arteriovenous malformation (AVM) was 14.06%(9/64). Moyamoya disease was 7.81%(5/64). Conclusions The main etiologic factors of stroke in middle aged and young patients are cerebral aneurysm, AVM. They are often found in hemorrhage stroke. Most patients can be diagnosed with DSA, but it need to be investigated more.
