立体定向显微手术摘除脑内海绵状血管瘤

目的脑内海绵状血管瘤病灶多较小，位置较深，传统手术或难以准确定位或可造成较大的脑损伤。本将探讨定向开颅术在脑内海绵状血管瘤的应用。方法以立体定向显微脑手术除了９例位于脑深部的小型（直径０．８－１．４ｃｍ）海绵状血管瘤。手术技术主要包括计算机体层摄影（ＣＴ）立体定位，小骨窗开颅和标准显微外科病灶切除。结果９例病人的海绵状血管瘤得以全切，而未造成术后严重神经功能障碍。全部病人在６－１７个月的术后随

Stereotacticallyguided microsurgical excision of brain cavernous angioimas

Objective To study the effectiveness of stereotactic craniotomy technique in the exision of hrain cavernous angiomas.Method Nine patients underwent stereotactic microsurgical excision of small (0.8-1.4cm in diameter) and deep-seated braincavernous angiomas in this series. The surgery consisted of a stereotactic loealization, small craniotomy and standardmicrosurgical excision of the lesion. Result With this procedure, the cavemomas in all 9 cases were removed completely whichhave no postoperahve neurological deficit,and all patients experienced disorder control (especially seizure) improved during thefollow-up of 6-17 months. Conclusion The stereotactic microsurgical technique is optimal to the management of cavemousangiomas. It is important to remove the surrounding rim of gliosis with haemosiderin deposition as well as the maiformation corefor achieveing satisfactory outcome (seizure control in particular).
