Association of portal hypertension and ruptured splenic artery aneurysm in pregnancy.

Spontaneous rupture of a splenic artery aneurysm is a rare, usually catastrophic event complicating pregnancy. Among risk factors for splenic artery aneurysm in nonpregnant patients is portal hypertension. The third case of rupture of splenic artery aneurysm in a patient with portal hypertension is reported, and previous reports are reviewed. In each of these cases the portal hypertension was due to hepatic cirrhosis. A previously unreported association between portal hypertension in pregnancy and rupture of a splenic artery aneurysm is presented.
