脑瘤的病理诊断不论对选择治疗方法或是估计预后都有十分重要的意义。脑血管造影上出现的病理循环常可帮助确定脑瘤的病理性质,但鉴别诊断有时仍很困难。本文分析脑血管造影上出现病理循环并经手术及病理证实的87例,探讨了有关鉴别诊断的问题。病理分类和部位(见表),摄影技术是前后位摄照动脉期一张,侧位摄照动脉期及静脉期各一张,间隔3—4秒。 Pathological diagnosis of brain tumors, whether the choice of treatment or prognosis are of great significance. The pathological appearance of cerebrovascular angiography can often help determine the pathological nature of brain tumors, but the differential diagnosis is sometimes still difficult. This article analyzes the pathological circulation on cerebrovascular angiography and confirmed by surgery and pathology in 87 cases, to explore the differential diagnosis. Pathological classification and site (see table), photographic technique is an anterior and posterior pharyngeal arterial phase, side of the arterial phase and venous phase of a photo, at intervals of 3-4 seconds.
