Abstract:
Objective To explore the process and technique ofneuroendoscopic operation in obstructive hydrocephalus caused by cysts of the posterior fossa. Methods An analysis of 31 patients with obstractive hydrocephalus caused by cysts of the posterior fossa, admitted to our hospital from April 2004 to August 2010, was performed; CT and MRI were performed on these patients. Among all the 31patients, 19 had arachnoid cyst of the posterior fossa, 5 Dandy-Walker malformations, 2 Blake' s pouch cyst, and 5 cysts after resection of the tumor. Treatment efficacy was determined according to the improvement of clinical symptoms, imaging manifestations and appearing of relative complications.Results Endoscopic management (n=14), microsurgery (n=9) and ventriculoperitoneal shunt (n=8) were performed. All the patients' postoperative hydrocephalus was alleviated in early stage of treatnent.Subsequent follow-up, ranged from 0.6 to 6 years, revealed a sharp reduction of sizes of the cyst and ventricle system under MRI in 28 patients, with a total effective rate of 87.1％. The effective rate and incidence of complications were 92.9％ and 14.3％ in patients performed endoscopic management, 88.9％and 33.3％ in patients performed microsurgery, and 75％ and 50％ in patients performed ventriculoperitoneal shunt, respectively.Conclusion Neuroendoscopic procedure is a safe and effective technique for hydrocephalus caused by cysts of the posterior fossa; as compared with those with microsurgery and ventriculoperitoneal shunt, higher success rate and less operative complications are achieved in patients with endoscopic management.
