A case of aortocaval fistula complicating a ruptured infrarenal aortic
aneurysm is reported. As the length of the defect and the thickness o
f the aortic wall made repair from within the aorta unsafe, the defect
was repaired from within the vena cava. The details of the technique
are reported. It can be a useful alternative to inferior vena cava lig
ation, when standard repair of aortocaval fistulae from within the aor
ta is risky or difficult to attempt.
