SLT接触式激光治疗脑深部肿瘤(附6例报告)

Application of SLT contact laser in the treatment of deep brain tumors (A report of 6 cases)

应用ＳＬＴ接触式激光显微手术治疗脑深部肿瘤６例，即颅底脑膜瘤４例，丘脑肿瘤１例，枕部小脑幕切迹室管膜瘤１例。其中１例岩—斜坡复发性脑膜瘤次全切除，其余３例脑膜瘤中１例蝶骨嵴内侧脑膜瘤及２例嗅沟脑膜瘤全切。１例丘脑肿瘤大部切除，接触式激光直接接触肿瘤组织，局部温度可达４００℃，可迅速汽化、切割肿瘤，避免了激光的散射及侧射，减少对周围组织的损害，术后脑水肿反应轻，止血效果好，又可控制穿透深度，对部位深在。

Six intracranial deep tumors were treated using the SLT contact laser produced by the Medi-Therm company of America.There were 4 basilar meningiomas,1 thalamic tumor and 1 ependymoma of occipital incisura tentorii. Total resections were done in 3 cases of meningiomas,including 1 sphenoid ridge meningioma and 2 olfactory groove meningioma,and subtotal in 2 cases,including 1 ependymoma and 1 recurrent petro-clivus meningioma.The other 1 case had gross partial removal of thalamic tumor.The operative effect was satisfactory.The SLT contact laser has the following advantages:having the ability to precisely dissect and vaporize the tumor,without peritumoral normal brain tissue injury very mild postoperative brain edema,and excellent hemostatic effect.Sum up,using SLT contact laser in the treatment of deep brain tumors is technically feasible,effective and safe.The manipulative skills of this device also have been discussed.
