Endovascular stent-graft repair of spontaneous aorto-caval fistula secondary to a ruptured abdominal aortic aneurysm: An emergency management of hostile anatomy.

Objective: Although endovascular aneurysm repair of aorto-caval fistula offers a safe and efficient approach compared to traditional open repair, endovascular techniques for the treatment of aorto-caval fistula with ruptured abdominal aortic aneurysms in emergency circumstance are not well established. This study aims to evaluate the effect of endovascular repair of aorto-caval fistula of a patient with ruptured abdominal aortic aneurysm and hostile anatomy.

Methods: we report a case of an aorto-caval fistula endovascular repaired in a 78-year-old male using a hybrid stent-graft technique.

Results: The patient had an uneventful recovery and CTA follow up showed no sign of ACF or any endoleak.

Conclusions: This case highlights ACF might be managed by composite endograft implantation with careful and solid sealing of anchoring zones on the two sides.
