Abstract

Abdominal aortic aneurysms are a chronic dilation of the aorta with a natural history toward enlargement and rupture. It’s a substantial burden on health care. Their incidence has increased during the past two decades, due in part to the aging of the population and the introduction of screening programmes. Although some patients have vague symptoms, such as back pain or abdominal pain, most abdominal aneurysms are asymptomatic until rupture, which leads to death in 66% of patients. The most important complication of infrarenal aortic aneurysms is rupture into the retroperitoneal space or the abdominal cavity. Rupture into the vena cava is uncommon. The incidence of aorto-caval fistulas varies from 2 % to 4 % of the cases. In this article we describe the case of an 81 years old man who had asymptomatic infrarenal aorticaneurysm ruptured into the retroperitoneum and into the inferior veina cava.
