Radiosurgery for Cerebrovascular Disease / 대한뇌혈관학회지

ABSTRACT

The stereotactic radiosurgery for arteriovenous malformation (AVM) began in the early 1970s. Nowadays, by 2000 world-wide, more than 27,500 patients have undergone Gamma Knife radiosurgery for cerebrovascular disease (CVD). New concepts, consisting of obliteration rate, postradiosurgical hemorrhagic risk, dose selection for treatment, and radiosurgery for pediatric AVM, medium-to-large sized AVM, cavernous malformation, venous angioma, so on, have been established. Gamma Knife radiosurgery has been considered as an effective management stratege with relatively few side effects for AVM. However, recently delayed radiation-induced complications were reported in 3.2 to 12.5% in range. Therefore, the long-term follow-up is thought to be mandatory even after treatment goal, complete obliteration, is confirmed.
