CT下腰穿逆行性脑室造影局限性脑室扩大的临床意义

Clinical significance of retrograde CT-ventriculography following lumbar puncture in diagnosis of local ventricular dilatation

目的:探讨CT下腰穿逆行性脑室造影局限性脑室扩大的临床意义。方法:对32例局限性脑室扩大患者,分别在CT下行腰穿术非离子型造影剂逆行性脑室造影。结果:27例为脑室囊肿,5例为单纯局限性脑室扩大。结论:CT下腰穿逆行性脑室造影可鉴别脑室囊肿及单纯局限性脑室扩大;对颅内蛛网膜囊肿、脑积水梗阻定位诊断具有重要意义。

Objective. To explore the clinical significance of retrograde CT-ventriculography following lumbar puncture in the diagnosis of local vcntricular dilatation. Methods： A retrospective study was performed on 32 patients with local ventricular dilatation ,who were admitted to our department and were examined with retrograde CT-ventriculography following lumbar puncture . Results： With the new method, 27 cases were diagnosed as; ntraventricular cyst, and 5 cases as local ventrieular dilatation. Conclusion： The retrograde CT-ventriculography following lumbar puncture can distinguish ventricular cyst and local ventricular dilatation; and is of great significance in localizing diagnosis of intracranial arachnoid cyst and obstructive hydrocephalus.
