Hepatic artery calcification in a liver transplant recipient.

The abdominal aorta and the renal, mesenteric, and splenic arteries are frequently affected with arterial wall calcification upon increasing age; the hepatic artery is far less often found to be calcified. We report the case of a liver transplant recipient who presented with a calcified hepatic artery in the liver graft 13 years after transplantation for primary sclerosing cholangitis. Although the etiology of hepatic artery calcification was unknown, underlying causes for calcification may include chronic hemodialysis for renal insufficiency and subsequent secondary hyperparathyroidism, as well as a calcified aneurysms. However, it remained unclear whether hepatic artery calcification had to be considered an epiphenomenon or an original pathology of the liver. It thus seems unlikely that hepatic artery calcification as a single finding is to be considered a serious pathologic entity, even for a liver graft.
