Abstract
Aortocaval fistula (ACF) is a rare complication of abdominal aortic aneurysms (AAA),
involving less than 1% of all AAA and is associated with high morbidity and mortality;
it is even more uncommon, following endovascular aneurysm repair. The clinical presentation
can be variable and making the diagnosis can be difficult. It can present with symptoms
and signs of an abdominal emergency or systemic hypoperfusion. The traditional method
of repair has been open surgery, which is associated with a high mortality rate. Endovascular
repair has become more common, but results are difficult to interpret due to the low
incidence of ACF. A high index of suspicion is imperative to avoid delay in diagnosis
and care.
