近五年脑立体定向术与CT的配套应用,收效良好。其中较先进的是Brown-Roberts-Wells System,BRWs型CT定向仪。本文作者报导应用此设备行脑瘤手术所取得的经验及方法,此方法目前较广应用于:1脑局部活检,作为精确组织学及微生物学分析;2囊性病变及脓腔内容物吸出;3放置临时或长期引流管;4作为脑内镜的活检或肿瘤切除精确导向;5手术中的定位与导向等。患者年龄18月到86岁不等。病例选择大致为:1病变位于脑深部或主要功能区;2放射学检查难以确诊的脑中线及松果体区肿瘤;3对手术适应症有争议的颅内病变,如非占位效应的肿瘤或具有潜在感染之病变;4身体状况不能接受开颅手术的患者;5粘液或侧脑室囊肿,鞍上及鞍旁颅咽管瘤;6直径小于1 cm的小病灶
The application of stereotactic brain CT and CT in recent five years has yielded good results. One of the more advanced is the Brown-Roberts-Wells System, BRWs CT orientation instrument. The authors report the experience and methods of using this device to perform brain tumor surgery. This method is currently widely used: 1 brain biopsy, as a precise histological and microbiological analysis; 2 cystic lesions and aspiration of the abscess content; 3 place temporary or long-term drainage tube; 4 as a brain endoscopic biopsy or tumor resection precise guidance; 5 positioning and guidance during surgery. Patients ranged in age from 18 months to 86 years. Case selection is roughly as follows: 1 The lesion is located in the deep brain or major functional areas; 2 The brain midline and pineal region tumors are difficult to be diagnosed by radiological examination; 3 The intracranial lesions that are controversial for surgical indications, such as non-occupying tumors Or have a potential infection of the lesion; 4 patients can not accept the craniotomy physical status; 5 mucus or lateral ventricle cyst, suprasellar and parasellar craniopharyngioma; 6 small lesions less than 1 cm in diameter
