ZUNIGA G, Carlo; RODRIGUEZ A, José Ramón y CACERES G, Patricio. Aortocaval fistula as a complication of abdominal aortic aneurysm. Rev Chil Cir [online]. 2011, vol.63, n.6, pp. 623-626. ISSN 0718-4026. http://dx.doi.org/10.4067/S0718-40262011000600013.
Aortocaval fistula (ACF) is an infrequent complication of abdominal aortic aneurysm (AAA). Diagnosis is suspected by the presence of a continuous abdominal bruit and pulsatile abdominal mass, with variable signs of venous congestion and acute heart failure. Multislice computed tomography (MSCT) is useful in establishing the diagnosis, showing early enhancement of inferior vena cava and, in some cases, identifying the arteriovenous comunication. Surgical treatment is usually complex, with high morbidity and mortality rates. Endovascular treatment seems to be a promising alternative for the management of these patients. We report a case of ACF treated with open surgery and a literature review of this rare condition.
