Renal Aneurysm In Pregnancy: A case of a renal aneurysm rupture with fetal demise.

Renal artery aneurysms (RAA) account for 1% of all aneurysms and 22% of visceral aneurysms. The incidence of RAA is approximately 0.09% and most are identified at autopsy or as an incidental finding on CT. 1 Although the incidence of rupture is relatively low, mortality to both fetus and mother is extremely high in RAA rupture during pregnancy and the consequences are often devastating with reported mortality rates of 70-80%. 2 Herein, a rare case of a ruptured renal artery aneurysm during pregnancy is presented. The influence of physiological changes of pregnancy in the progression of an existing RAA and the management of a newly discovered renal artery aneurysm in pregnancy are explored.
