Microsurgey Treatmeat of Intracranial Arachnoid Cyst

Objective:To study the result and the advantages of microsurgery treatment of intracranial arachnoid cyst(IAC).Methods:Date of 23 caces itracranial arachnoid cyst operated, in which cyst were performde in 3, cyst removal pluscisternel opening in 13, and cyst-peritoreal shunt in 7. Different methods of operation were analyzed comparatively. Results:Of 23 caces, the chief symptoms of 7 got disapeared (cyst removal plus cisternel opening in 5 and cyst were performed in 2), the chief symptoms of 12 got improved in 82.6% of the patients, part of the chief symptoms of 1 got better; 2 caces recured, one of cyst-peritoneal shunt result in the shunt blocked up, and another one case of cyst removal plus cisternel opening got a good outcome by cyst-periconeal shunt. Conclusions:Cyst resection plus cisternel opening by microscope is pefferred in the treatmen of intracranial arachnoid cyst, and the cyst-peritoneal shunt had a better curative effect when the cyst area exceeded half of the cerebral hemisphere.
