Objective:
To evaluate the therapeutic effect of gamma knife on patients with intracranial cavernous angioma (CA).
Methods:
The medical records of 122 patients (134 lesions) who underwent radiosurgery were reviewed retrospectively.
Results:
Th e average follow-up period was 43 months. No patient died. One patient underwent CA resection. In patients with epilepsy, 83% patients showed alleviation of seizures. About 44% of the lesions shrank in size after treatment with gamma knife radiosurgery (59/134). Seven cases had hemorrhage again after radiosurgery, and the overall annual hemorrhage rate was 1.6%. Edema was found in 11.5% patients (14/122) and all patients showed improvement aft er treatment.
Conclusion:
Gamma knife is a safe treatment for CA, which could obviously improve the symptoms of epilepsy. Gamma knife radiosurgery is the fi rst option for the treatment of cavernous sinus angiomas.
