Radiosurgery for Cerebral Arteriovenous Malformation (AVM) : Current Treatment Strategy and Radiosurgical Technique for Large Cerebral AVM

---

Arteriovenous malformations (AVMs) are congenital anomalies of the cerebrovascular system. AVM harbors 2.2% annual
hemorrhage risk in unruptured cases and 4.5% annual hemorrhage risk of previously ruptured cases. Stereotactic radiosurgery (SRS)
have been shown excellent treatment outcomes for patients with small- to moderated sized AVM which can be achieved in 80–90%
complete obliteration rate with a 2–3 years latency period. The most important factors are associated with obliteration after SRS is
the radiation dose to the AVM. In our institutional clinical practice, now 22 Gy (50% isodose line) dose of radiation has been used for
treatment of cerebral AVM in single-session radiosurgery
