Abstract
A cyst-arachnoid shunt procedure using a silicone tube with many small holes at both ends was performed in two patients having anterior cervical intradural arachnoid cysts. In one patient aged 44 years, preoperative symptoms of nape pain and radicular pain in both upper extremities disappeared immediately after the operation. With a follow-up of 4 years and 8 months, no recurrent arachnoid cyst was seen on MRI. The other patient, aged 5 years, had progressive tetraparesis preoperatively. His neurologic deficits rapidly improved after the operation, leaving no disability after a follow-up of one year. This procedure can be an excellent alternative if the complete removal of the arachnoid cyst is difficult to achieve.
