Key result
Surgical repair successfully manages ruptured abdominal aortic aneurysm with thrombosed aortocaval fistula.
Why the study?
Ruptured abdominal aortic aneurysm with thrombosed aortocaval fistula and thrombosis of the inferior vena cava and iliac veins is a rare clinical condition requiring detailed imaging and surgical confirmation.
Case Report (n=1)
Highlights a rare presentation of ruptured abdominal aortic aneurysm with thrombosed aortocaval fistula and venous thrombosis, successfully diagnosed via multiphase CT and treated surgically.
Multiphase CT may detect thrombosed aortocaval fistula in ruptured AAA; leaves open need for validation before wider adoption.
This article considers a rare case of rupture of abdominal aortic aneurysm with thrombosed aorto-caval fistula formation, with thrombosis of the inferior vena cava and iliac veins. During the multiphase computed tomography, early enhancement of inferior vena cava was not obtained, but non-contrasting aorto-caval fistula was revealed in the venous contrast phase, as well as the absence of the contrast in the adjacent parts of the inferior vena cava and iliac veins. The patient was successfully operated and the diagnosis was confirmed intraoperatively.

Vishnyakova et al. (2022) conducted a case report in Ruptured abdominal aortic aneurysm with thrombosed aortocaval fistula (n=1). Surgery was evaluated on Surgical outcome and diagnosis confirmation. Surgical intervention successfully treated a rare case of ruptured abdominal aortic aneurysm with a thrombosed aortocaval fistula and confirmed the diagnosis intraoperatively.
