Marked hepatic congestion caused by a thoracoabdominal aneurysm.
A 70-yr-old man with a large thoracoabdominal aortic aneurysm developed marked congestive hepatomegaly. Evaluation by arteriography, venography, and computed tomography revealed compression and venous obstruction at the confluence of the hepatic veins and inferior vena cava. Although obstruction of the inferior vena cava caused by rupture of an abdominal aortic aneurysm is known to occur, obstruction without rupture and involving the hepatic veins has not been previously reported.
