Objective: To evaluate the usefulness of multistage intraoperative indocyanine green (ICG) videoangiogrpahy during surgical procedure for intracranial dural arteriovenous fistula (AVF).

Methods: The method was applied for a patient with the left convexity parasagittal dural AVF. A 41-year-old man suffering from right hemiplegia caused by left subcortical hemorrhage due to the dural AVF.

Results: He underwent surgical resection of the dural AVF. In this operation we performed step-by-step ICG videoangiography 4 times in each dissection procedure of the fistula, which provided us precise structure of the dural AVF. After circular incision of the dura around the fistular point, repeated ICG videoangiography indicated the residual fistula between the pial artery from the middle cerebral artery (MCA) and the draining vein. Complete disappearance of the AVF was confirmed by ICG videoangiography after removing this pial fistula. Postoperative DSA also revealed no residual AVF.

Conclusions: Accurate detection of all fistular points and complete resection including the dura mater and pial vessels are necessary to avoid rebleeding caused by the residual AVF due to incomplete obliteration of the fistular points. The intraoperative ICG videoangiography could provide information of angiographically occult vascular malformation such as the pial fistulas that could not be detected by preoperative DSA. These findings suggest that multistage intraoperative ICG videoangiography would be quite useful for complete resection of the dural AVF with angiographically occult pial fistula.
