We found splenic artery aneurysms in 6 of 71 consecutive patients who underwent orthotopic liver transplantation at the Mayo Clinic. The incidence of splenic artery aneurysms in cirrhotic patients with portal hypertension was 10%. Five of the aneurysms were found in patients suffering from chronic active hepatitis, whereas no aneurysms were encountered in patients with primary sclerosing cholangitis or primary biliary cirrhosis. One patient ruptured a splenic artery aneurysm shortly after liver transplantation, and 1 patient developed an aneurysm 3 months after transplantation. We recommend coeliac angiography to be performed prior to liver transplantation, and if splenic artery aneurysms are found, ligation of the splenic artery should be performed at the time of transplantation to prevent possible rupture.
