Angiographic disappearance of multiple dural arteriovenous malformations

Abstract

✓ Angiographic disappearance of two dural arteriovenous malformations (AVM's) in different locations in one case is reported. One of the AVM's involved the right transverse sinus, and the other involved the superior sagittal sinus. The patient's presenting symptoms were due to obstructive hydrocephalus resulting from a small intraventricular hemorrhage that was diagnosed by computerized tomography on admission. The symptoms cleared 25 hours after the ictus in conjunction with improvement of hydrocephalus. The AVM involving the right transverse sinus was supplied by the occipital artery, but ligation of that artery was not successful in eliminating the anomaly. One year later, follow-up angiography revealed disappearance of both dural AVM's.
