Brief Report: Concurrent cervical giant perimedullary arteriovenous fistula aneurysm on a feeding artery of fistula and unilateral congenital carotid aplasia

摘要

Giant perimedullary arteriovenous fistulae (GPAVFs) are extremely rare, particularly cervical GPAVFs whose incidence has not been tabulated. The occurrence of aneurysm on an artery feeding a GPAVF has previously not been described. Internal carotid artery aplasia is also very rare (0.01%). The concurrence of these disorders has previously not been recorded. We report a case of a 5-year-old female with increasing headaches, who was found to have intraventricular hemorrhage and above anomalies. Coil embolization of GPAVF and the adjacent aneurysm was attempted. Treatment was complicated by stroke and death. Embryological and anatomical factors underlying these anomalies as well as, management options are discussed.
