Endovascular treatment of ruptured abdominal aortic aneurysm with aortocaval fistula based on aortic and inferior vena cava stent-graft placement.

A ruptured abdominal aortic aneurysm (RAAA), complicated by an aortocaval fistula (ACF), is usually associated with high morbidity and mortality during open operative repair. We report a case of endovascular treatment of an RAAA with ACF. After accessing both common femoral arteries, a bifurcated aortic stent graft was placed. Subsequently, we accessed the fistula from the right femoral vein and a cava vein angiography showed a persistent massive flow from the cava to the excluded aneurysm sac. We proceeded by covering the fistula with an Excluder aortic stent-graft cuff to prevent pressurization of the aneurysm sac and secondary endoleaks. This procedure is feasible and may reduce the chances of posterior endoleaks.
