激光在内窥镜立体定向神经外科应用的实验与临床研究

Experimental and Clinical Study of Laser inEndoscopy-stereotactic Neurosurgery

文章就Nd:YAG激光在内窥镜立体定向神经外科应用的实验及初步临床研究进行介绍.实验研究显示:Nd:YAG激光汽化范围极有限,深在凝固作用显著,冲水对减轻水肿有一定作用.在动物实验的基础上将激光应用于内窥镜立体定向手术治疗了12例脑深部及功能区病变,其中切除脑肿瘤6例;去除脑脓肿2例;脑寄生虫摘除1例;颅内金属异物摘除3例;所有病例进行了内窥镜直视下的活检.取得较好的临床效果.认为此种手术具有创伤小、直视下操作及并发症少等优点.

This article described the animal experiment and primary clinical application of Nd: YAG laser in endoscopy-stereotactic neurosurgery. The experiment shows that vaporization ofNd: YAG laser is so limited and necrosis is significant. Irrigation is benifit for decreasing thelaser-induced edema. On the basis of animal experiment, Application of laser in endoscopy-stereo-tactic neurosurgery had been underdone in 12 patients whose lesions located in deep-sited and func-tional areas since September, 1994. Brain tumors were resected totally or partly in 6 cases. Ab-scesses were aspirated and removed in 2 cases. Parasite in 1 case and intracranial foreign metalbodies in 3 cases were extracted. Biopsies were made under direct visualization in all cases. Goodresults were obtained. It is considered that ELS has advantages of minimal invasion, direct intra-operative visualization and less complications.
