颅内蛛网膜囊肿的显微手术治疗

目的：探讨显微手术治疗颅内蛛网膜囊肿的疗效及优越性。方法：回顾性分析23例蛛网膜囊肿病例，均手术治疗，其中囊肿切除3例、囊肿部分切除 脑池开放术13例、囊肿一腹腔分流术7例，比较各种方法的治疗效果。结果：23例中症状消失7例(囊肿部分切除 脑池开放术5例，囊肿全切2例)，明显改善12例，显效率82．6％，部分缓解1例；复发2例，其中1例囊肿-腹腔分流术，分流管堵塞；另1例囊肿部分切除 脑池开放术1例，改行囊肿-腹腔分流术，效果良好。结论：蛛网膜囊肿的治疗首选显微镜下囊壁切除 脑池开放术，囊肿面积超过大脑半球一半时以囊肿-腹腔分流术疗效较佳。

Microsurgey Treatmeat of Intracranial Arachnoid Cyst

Objective:To study the result and the advantages of microsurgery treatment of intracranial arachnoid cyst(IAC).Methods:Date of 23 caces itracranial arachnoid cyst operated, in which cyst were performde in 3, cyst removal pluscisternel opening in 13, and cyst-peritoreal shunt in 7. Different methods of operation were analyzed comparatively. Results:Of 23 caces, the chief symptoms of 7 got disapeared (cyst removal plus cisternel opening in 5 and cyst were performed in 2), the chief symptoms of 12 got improved in 82.6% of the patients, part of the chief symptoms of 1 got better; 2 caces recured, one of cyst-peritoneal shunt result in the shunt blocked up, and another one case of cyst removal plus cisternel opening got a good outcome by cyst-periconeal shunt. Conclusions:Cyst resection plus cisternel opening by microscope is pefferred in the treatmen of intracranial arachnoid cyst, and the cyst-peritoneal shunt had a better curative effect when the cyst area exceeded half of the cerebral hemisphere.
