Arteriovenous fistula aneurysm video

ARTERIOVENOUS fistula (aneurysm) connecting the great cerebral vein (of Galen) and the circle of Willis is a congenital anomaly, apparently of rare occurrence and heretofore a pathologic curiosity. Only 6 examples of this defect have, to our knowledge, been described, 5 in the literature and 1 in a personal communication. In 5 cases the condition was noted at autopsy; in the sixth the diagnosis was made on the basis of observation at operation. The purpose of this paper is to present the cases of 2 living patients in whom this anomaly was discovered by means of cerebral angiography, to discuss the clinical course and treatment of the condition in these 2 children and to suggest that the anomaly may be commoner than one might suppose
