The purpose of this presentation is to report three adult patients with aortoenteric fistula whose initial presentation was abdominal pain and digestive bleeding. We stress the low incidence of this disease as a cause of digestive bleeding, its high mortality and the need of high clinical suspicion for its diagnosis. We discuss the different sites of the aortoenteric fistulas, probable physiopathological mechanisms that generate them and their elevated association with the presence of vascular prostheses.

Budd-Chiari syndrome can be defined as an interruption or diminution of the normal blood flow out of the liver. Patients with Budd-Chiari syndrome present with varying degrees of symptomatology that can be divided into the following categories: fulminant, acute, subacute and chronic. The subacute form is the most common presentation. A majority of patients with Budd-Chiari syndrome have an underlying hypercoagulability state. We present the case of a young woman with Crohn's disease on oral contraceptives who developed bilateral pulmonary thromboembolism and Budd-Chiari syndrome.

In our region patients with WD are diagnosed at a younger age, and in most cases for hepatic disease. Patients with neurological disease or liver cirrhosis had a high level of free copper not associated to ceruloplasmin and cupruria. The disease had a favorable evolution in all patients but those diagnosed with hepatic disease or advanced neurological disease.
