Spontaneous aortocaval fistula is a rare but documented complication of arteriosclerotic abdominal aortic aneurysm. Most cases reported have presented clinically with a palpable aneurysm, abdominal bruit, and high output congestive heart failure. A diagnosis in such cases requires active demonstration of findings secondary to arteriovenous shunting, which can be optimized utilizing proper CT bolus technique and dynamic scanning. We describe several CT findings--all of which may be typical for and support the diagnosis of this potentially lethal complication of abdominal aortic aneurysm.

Aortocaval fistulas, typically linked to aortoiliac aneurysms, are rare vascular conditions. Currently, endovascular therapy is preferred treatment approach. However, endovascular therapy requires frequent and extended follow-up evaluations.

Purpose: We described an alternative access for thoracic endovascular aortic repair (TEVAR) deployment using a transjugular intrahepatic portosystemic shunt (TIPS) needle for gaining transcaval access to the abdominal aorta.
Case Report: A 63-year-old man presented with a penetrating atherosclerotic ulcer in the descending aorta. Traditional transfemoral and transaxillary access were not possible.

Background: Arteriovenous fistulae (AVF) are the preferred vascular access for hemodialysis in patients with end-stage kidney disease. Chronic kidney disease (CKD) is associated with endothelial injury, impaired AVF maturation, and reduced patency, as well as utilization. Because CKD is characterized by multiple pathophysiological processes that induce endothelial-to-mesenchymal transition (EndMT), we hypothesized that CKD promotes EndMT during venous remodeling and that disruption of endothelial TGF (transforming growth factor)-β signaling inhibits EndMT to prevent AVF failure even in the end-stage kidney disease environment.

Article Synopsis
- This study evaluates the outcomes of open surgical repair in 39 male patients with aorto-caval fistula caused by spontaneous rupture of an abdominal aortic aneurysm, documenting a high 30-day mortality rate of 35.9%.
- The research involved a thorough review of clinical records at a Serbian medical center from January 2012 to February 2023, with a mean follow-up of 3.7 years for those who survived the surgery.
- The findings suggest that given the serious nature of ACF and the risks associated with open repair, endovascular repair techniques are recommended as they may offer better outcomes.
