     Stereotactic radiosurgery is an advanced technique in the field of neurosurgery. 
     We present our experience at Department of Neurosurgery, Ibn Sina Hospital.
     There were 81 male and 77 female patients and the ages ranged from 12 to 76 years.
     First Leksell Gamma Knife® (Model 4-C) became functional in the Arabian Gulf at Ibn Sina Hospital, Kuwait in July, 2008. We have treated 158 patients with different brain disorders at our center.  Eighty one patients were treated for benign brain tumors; 23 with gliomas; 22 with brain metastases; 26 with vascular malformations (AVM-23; Cavernous malformations-3) and 6 patients with trigeminal neuralgia. Three patients underwent radiosurgery in 2 sessions. Most of the patients had residual or recurrent lesions after surgical excisions.
     Post-radiosurgery follow-up was achieved in 142 (90%) patients and it ranged from 6-36 months. Overall the patients’ outcome was excellent. Complications were observed in 10 (6.3%) patients, of those 3 patients were managed with surgical excision after gamma knife radiosurgery. Fifteen (9.4%) patients (brain metastases=12 and GBM=3) expired due to progression of their primary diseases within one year after radiosurgery.
     This was a retrospective review.
     Stereotactic Radiosurgery is relatively a safe, effective and less expensive with minimum hospital stay. 
     It is potentially effective management for inaccessible, recurrent and residual brain lesions for which no other option exists.
