Successful Endovascular Repair of a Ruptured Common Iliac Artery Aneurysm Associated with an Ileal Pouch Neobladder Fistula.

A spontaneous fistula between a ruptured common iliac artery aneurysm and the ileal pouch neobladder is quite rare. We present the case of a 74-year-old man presenting with intense abdominal pain and massive hematuria. Computed tomography angiography revealed a ruptured common iliac artery aneurysm-ileal pouch neobladder fistula. His hemodynamics was unstable; emergent endovascular aortic repair was performed successfully. Infection and dysfunction of the neobladder were avoided owing to appropriate management.
