内镜下手术治疗颅内囊性病变

目的：探讨应用神经内镜手术治疗颅内囊性病变的手术适应证和手术方法。方法：采用单纯神经内镜下及神经内镜辅助显微镜下手术切除肿瘤、囊肿，囊肿－脑室和囊肿－脑池造瘘等方法治疗颅内囊性肿瘤、颅内蛛网膜囊肿、透明隔囊肿、侧脑室内囊肿等囊性病变51。结果：囊性肿瘤全切9例，囊肿切除6例，蛛网膜囊肿囊壁部分切除加囊腔－脑池造瘘23例，囊肿脑室造瘘13例，25例于术后3个月复诊，疗效较好。结论：应用神经内镜可以通过颅骨钻孔或小的骨瓣开颅手术治疗颅内囊性病变，手术副损伤小，疗效可靠。

Endoscopic surgery for intracranial cysts

Objective To report experiences of endoscopic surgery on 51 patients with intracranial cysts, according to which, discuss indications and techniques of surgery on it. Methods There were 51 patients with intracranial cystic lesions and intracranial cystic tumors underwent endoscopic neurosurgery and endoscope controled microneurosurgery.Results 9 cases with cystic tumors and 6 cases with intraventricular cysts underwent total resection, 23 cases with intracranial arachnoid cysts underwent cyst partial resection and cystocisternostomy. 13 cases with ventricle related cysts underwent cystoventriculostomy. Most of the intracranial cystic lesions in our group improved clinically and anatomically after surgery. There was a good effect according to 3 months followup in 25 cases.Conclusions Endoscopic neurosurgery and endoscope assisted microneurosurgery to treat intracranial cystic lesions via a burr hole or keyhole craniotomy, offer a minimally invasive technique, as well as reliable effect.
