A Clinical Comparative Study On Different Operation Methods For Surgical Treatment Of Intracranial Arachnoid Cyst In Children

ObjectiveTo explore the best operation method in order to standardize thesurgical treatment for intracranial arachnoid cyst in children.MethodsFollow-up investigation methods were used to study the results ofthree different operation methods for treating intracranial arachnoid cystin children, especially to contrast and analyze various quotas based on 89cases follow-up data(3rd,6th,12th month after operation)which couldevaluate correctly clinical general curative effect. Statistical analyseswere perfomed by SPSS11.0.ResultsThree different operation methods were adopted to treat 89 patientswith intracranial arachnoid cyst, in which cyst removal was performed in27cases(group A), cyst removal plus citemal opening throughmicrosurgical techniques in 41 cases(group B),and cystoperitoneal shuntin 21 cases (group C). All subjects were followed up at 3rd,6th,12th month. The rates of both improvement of chief clinical symptoms andcysts disappearance and shrinkage increased by the time after operation,up to 6th month after operation, the above-mentioned two quotas of groupA,B,C were 51.9%,80.5% and 71.4% and 48.1%, 82.9% and 71.4%,respectively; up to 12th month, it was 63.0%, 92.7% and 90.5%; 55.6%,87.8% and 85.7% respectively, of three groups, group B had the highestrates among three groups with significant statistical difference (p＜0.05).At 12th month after operation, more patients with intracranial arachnoidcyst accompanied epilepsy became seizure-free or had less seizure attackin craniotomy (group A and group B,50.0%)than in cystopentoneal shunt(group C, 25.0%)but there was no significant difference among threegroups. No recurrence of cysts was found at 3rd month after operation,until 6th,12th month, there was recurrence of cysts in every group, ofthem, the recurrence rate of group B was lower, especially compared withthat of group A, but similarly no significant difference exsited amongthree groups. In addition, the incidence rate of post-operationcomplications in 3 groups showed no significant difference(P＞0.05). Ina word, comparison of clinical general curative effect among allgroups(A,B,C)showed that microsurgical cyst removal plus cisternalopening to treat intracranial arachnoid cyst in children was the bestmethods of operation.Conclusions The surgical treatment for intracranial arachnoid cyst in childrenthrough microsurgical cyst removal plus cistemal opening might be thebest method of operation and could be chosen first. Besdes, standardizedoperation sequences must be emphasized in order to reduce probability ofappearance of post-operation complications.
