Grosse jambe rouge aiguë fébrile révélant une fistule aorto-duodénale

Aortoduodenal fistula is a rare complication of vascular prostheses. Clinical features include digestive symptoms and fever. However, diagnosis may be difficult and delay surgery. Cutaneous manifestations appear later and are often associated with other symptoms; they are caused by septic emboli or vascular compression. Imaging methods may assist diagnosis, but surgical procedures provide confirmation and form the cornerstone of management.
