A Case of Abdominal Apoplexy / 日本心臓血管外科学会雑誌

ABSTRACT

This is a rare case of abdominal apoplexy encountered in a 50-year-old man who had aortic and mitral valve replacement due to dominant regurgitation resulting from infective eneocarditis. On the 4th day after the operation, retroperitoneal bleeding, probably due to rupture of the splenic artery aneurysm, occurred and he developed shock. On the 28th day, there was bleeding in the digestive tract and blood pressure was low, probably due to rupture of the microaneurysm of the small artery distributing to the ileum. Rupture of an abdominal vessel without a recognizable external cause is called abdominal apoplexy, and our case was caused by mycotic aneurysm caused by infective endocarditis. Angiography facilitated the accurate diagnosis.
