Usefulness of repetitive intraoperative indocyanine green-based videoangiography to confirm complete obliteration of micro-arteriovenous malformations.

ABSTRACT: BACKGROUND:It is difficult to intraoperatively confirm the total disappearance of arteriovenous (AV) shunts during surgery for microarteriovenous malformations (micro-AVMs), especially when the nidus is extremely small or diffuse on preoperative angiography. Although intraoperative angiography is effective for evaluating residual shunts, procedure-related risks raise important concerns. The purpose of this study was to assess the usefulness of intraoperative indocyanine green-based videoangiography (ICG-VA) to determine complete disappearance of micro-AVMs during surgery. METHODS:We retrospectively analyzed eight patients with ruptured micro-AVMs who were treated using craniotomy with ICG-VA at our institution. RESULTS:Two patients underwent emergency partial evacuation of hematoma and ext
