OBJECTIVE: To evaluate the method, strategy and efficacy of treating different types of quadrigeminal cistern arachnoid cysts (QCAC) with neuroendoscope.
METHODS: A retrospective analysis was conducted for 12 QCAC patients with obstructive hydrocephalus. They were classified into 3 types and underwent neuroendoscopic operation at our hospital between November 2005 and November 2009. Their surgical approaches, complications and efficacy were analyzed. The mean age of first diagnosis was 3.7 years old. There were 7 type II cases and 5 type III cases with a varying level of symptoms. The follow-up period was 6 - 24 months. Cine-MRI (magnetic resonance imaging) examination was performed both preoperatively and post-operatively.
RESULTS: Among them, 12 patients recovered well without any occurrence of hemorrhage, paralysis, lower cranial nerve injury, cerebrospinal fluid leakage, infection or death. Subdural effusion occurred in 3 cases, but disappeared within 6 months. Seven feverish cases recovered after a symptomatic treatment. The shapes of cysts and ventricles almost returned to a normal level in 8 cases. Three cases of arachnoid cyst had a slight change.
CONCLUSION: In accordance with the QCAC patient types, different neuroendoscopic approaches can fully reconstruct the cerebrospinal fluid circulation. And the use of frameless navigation makes it more precise and safe.
