[Methods and results of stereotactic radiosurgery for cavernous angiomas]

Stereotactic radiosurgery was performed in 42 patients (1997-2007). They presented with 47 cavernous angiomas and 44 of them underwent surgery. Single focal dosage varied 3-9 Gy while total one--18-54Gy. After treatment and 2-year followup, neurologic symptoms regressed in 21 (68%), tumors were smaller (MRI) in 10 (32.3%) and severe convulsions abated in 5 patients out of 9. No cerebral hemorrhage was reported within 9 years although 63.7% of tumors were located in deep cerebral structures and hemorrhage occurred as a precursor in 83%.
