RT Journal Article SR Electronic T1 Pulsatile Tinnitus from Reversal of Flow in an Aberrant Occipital Artery: Resolved after Carotid Artery Stenting JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 995 OP 997 DO 10.3174/ajnr.A1393 VO 30 IS 5 A1 P.O. Cowley A1 R. Jones A1 P. Tuch A1 W. McAuliffe YR 2009 UL http://www.ajnr.org/content/30/5/995.abstract AB SUMMARY: Carotid artery stent placement, performed for correction of an asymptomatic severe stenosis, leads to the resolution of persistent and troublesome pulsatile tinnitus. Tinnitus has been reported as a consequence of severe carotid stenoses on previous occasions. This case highlights how an aberrant occipital artery originating above a carotid artery stenosis can result in flow reversal and be a mechanism by which tinnitus may develop.
