蛛网膜囊肿伴癫痫的外科治疗

Surgical Treatment of Arachnoid Cyst Accompanied with Epilepsy

目的:探讨颅内蛛网膜囊肿(AC)与癫痫的关系以及外科治疗方法。方法:手术治疗AC伴癫痫23例,其中额叶4例,顶叶4例,颞叶13例,枕叶2例;囊肿直径在3cm以下5例,3～6cm 15例,6cm以上3例;采用AC+致痫灶切除21例,AC腹腔分流术1例,胼胝体切开术1例。结果:23例病人中,完全不发作有5例,显著改善有11例,无变化7例。结论:颅内蛛网膜囊肿(AC)可引起癫痫,采用AC+致痫灶切除效果较为理想。

Objective: To survey the relationship between intracranial arachnoid cyst (AC) and epilespsy and to explore the surgical treatment for them. Methods: Twenty - three patients with AC accompanied by epilepsy were performed surgical treatment. The Ac in four cases were located in frontal lobe, four in parietal lobe, thirteen in temporal lobe and two in occipital lobe. The diameter of five cysts were less than 3cm, fifteen between 3 - 6cm and three over 6cm. The AC and epileptogenic zone were resected in 21 patients,cysto- peritoneal shunt were performed in 1 and callosetomy in 1. Results:Postoperatively 5 patients were seizure free, 11 patients improved and 7 patients remained unchanged. Conclusion: Intracranial AC can cause epilepsy,and resection of AC and epileptogenic zone is a relatively ideal method.
