Aortocaval Fistula Caused by Erosion of a AAA into the IVC

This series of digital aortograms shows a rotund fusiform infrarenal aortic aneurysm (a, c – red overlay)) which later in the study shows premaure filling of the IVC (b, d blue overlay). This is an example of aneurysmal erosure of the the IVC and secondary formation of an arteriovenous fistula. Courtesy Laura Feldman MD 35858c03CP code CVS aorta IVC aneurysm AAA AV fistula
