儿童椎管内硬脊膜外蛛网膜囊肿的外科治疗

目的 探讨儿童椎管内硬脊膜外蛛网膜囊肿的临床特点及其诊治.方法 回顾性分析2001年1月至2009年8月我科收治的4例儿童椎管内硬脊膜外蛛网膜囊肿.其中颈胸段1例,胸腰段3例.临床表现3例患儿出现运动障碍,1例有感觉障碍,1例有小便失禁,1例有根痛表现.4例患儿均采用外科手术治疗,其中2例囊肿节段小于3个椎体的采用椎板切除+囊肿切除术,2例囊肿节段大于3个椎体的采用椎板成形+囊肿切除术.结果 4例患儿术后均恢复良好,除1例患儿术后随访1年下肢仍有轻度乏力外,其余临床症状均消失,恢复学习.随访1～9年均未见囊肿复发,复查脊柱三维CT未见脊柱畸形的发生.结论 儿童椎管内硬脊膜外蛛网膜囊肿是一种少见疾病,外科手术治疗能获得满意的结果,椎板成形术能够减少囊肿节段过长的患儿术后脊柱畸形的发生.

Abstract：

Objective To review the clinical features and surgical treatment of spinal extradural arachnoid cysts (SEACs) in children. Methods Four children with SEAC from were admitted to our department between January,2001 to August,2009. One SEAC was located at the cervicothoracic spine whereas the other three were found in the thoracolumbar spines. All cases were treated by surgery.Two children underwent the laminectomy for resection of the SEAC, which occupied less than 3 segments. SEAC, spreading more than 3 segments in the remaining cases, were treated by laminoplasty and en bloc resection. Results Postoperatively, the children had good recovery and resumed school. Followup of 1 to 9 years revealed no recurrences. The three-dimensional CT spine did not demonstrate any spine deformity in follow-up study. Conclusions SEACs in children are rarely reported in the literature. Excision of the SEAC result in a favorable outcome. The larninoplasty can reduce spinal deformity in patients with the long segment SEAC.
