Endovascular aneurysm repair of aortocaval fistula presenting with lower limb edema: A case report

Aortocaval fistula (ACF) due to a ruptured abdominal aortic aneurysm is an uncommon medical condition that can be fatal if not diagnosed. ACF has several atypical signs and symptoms, making it challenging to diagnose, and an early diagnosis notably improves outcomes. We report a case of a 64-year-old man presenting with a 1-day history of lower back pain, hypotension, and lower limb edema. Computed tomography angiography demonstrated an abdominal aortic aneurysm with ACF. An urgent endovascular aneurysm repair was successfully performed to treat the ACF in this patient. Eighteen months later, the patient had an intact stent, normalized renal function, and no edema.
