囊肿-腹腔分流术治疗儿童颅内蛛网膜囊肿

目的 研究非开颅术（囊肿－腹腔分流术）治疗颅内蛛网膜囊肿的手术方法。方法 对颅内表浅部位的蛛网膜囊肿，行囊肿－腹腔分流术。结果 ５１例１５岁以下的病儿行囊肿－腹腔分流术，２３例得到随访。１年内囊肿完全消失率７４％，其余病例逐渐缩小，总体有效率（囊肿消失和缩小）１００％。有３例颅内分流管在囊壁外，再次行分流管调整术。结论 以囊肿－腹腔分流术代替传统的开颅术切除囊肿，具有手术简单、有效、并发症少、无复

Treatmentof intracranial arachnoidal cyst with cystoperitoneal shunt in children

Objective To study a new operation using cystoperitoneal shunt for pediatric patients with intracranial cyst. Methods 51 cases with intracranial arachnoidal cyst were operated on cystoperitoneal shunt. All cases got CT and MR imagings after the surgery within one week. Mean age was 7 2 years (from 2 month to 15 years). Results Postoperative CT scan showed the intracranial tube did not in the cystic cavity in 3 cases, and secondary adjustment was needed. 23 cases got the follow up with 3 to 18 months (mean 7 4 months). The cystic cavity disappeared within one year in 74% cases. Other cases showed the cavity shrink significantly. Conclusions Compared with caraniotomy to resect arachnoidal cyst, the cystoperitoneal shunt is simple, effective, less complicate and no recurrence.
