Radiosurgery decreases the need for preoperative embolization and facilitates AVM resection. RS+ patients were less likely than RS− patients to undergo embolization prior to microsurgical resection (A). Operative time was less in RS+ patients compared to RS− patients (B). Blood loss was less in the RS+ group when compared to the RS− group (C). The number of operative stages tended to be lower for RS+ patients (D). The incidence of residual AVM was lower in RS+ patients (E). The incidence of post-operative hemorrhage was slightly lower in RS+ patients (F).
