颅内肿瘤IADSA诊断（附183例报告）

IADSA DIAGNOSIS OF INTRACRANIAL TUMORS:A REPORT OF 183 CASES

对手术病例证实的１８３例颅内肿瘤的ＩＡＤＳＡ资料进行回顾性分析，以进一步认识ＩＡＤＳＡ检查对颅内肿瘤的诊断作用及限度。结果表明：ＩＡＤＳＡ可显示８０．６０％的脑膜瘤、６７．６１％的胶质瘤，６８．１８％的垂体腺瘤、６６．６７％的听神经瘤及囊性血管母细胞瘤、颈静脉球瘤的血管结构及其特征，且可结合ＣＴ作出定性诊断及较准确的定位。还可进行供血动脉的介入性栓塞。

A retrospective analysis of 183 surgically and pathologically proved IADSA cases of intracranial tumors was made for further evaluationof the advantages and limits of the technique in diagnosis. The results ofthe study are following:vascular structures and characteristic angiogra-Phic signs was well depicted in 80.60%of meningioma cases,67.61%of glioma cases, 68.15%of pituitary adenoma cases,66.67%of acoustic neuro-ma cases,as well as cystic hemangioblastomas and glomus jugulare. Ratheraccurate localization and characterization of tumors could be made from these findings in combination with CT features. Interventional emboliza-tion of the feeding arteries could be done under appropriate conditions.
