Postoperative brain edema and/or hemorrhage is a serious problem especially arteriovenous malformations(AVM) in an eloquent area. It has ben a neurosurgical dilemma whether to surgically remove an unruptured AVM in an eloquent area. It is necessary to define the anatomic location, understand the hemodynamics, vasoreactivity of the adjacent brain parenchyma for safe removal of an AVM in an eloquent area. A successful removal of an AVM at an eloquent motor area without neurological deficit was made. We report method of localizating, angiographic anatomy, mechanism of possible hemodynamic insult related to operation.
Key Words: Eloquent motor area; Arteriovenous malformation; Hemodynamics; Vasoreactivity
