Introduction:
Fistula formation between an ileac artery and an ileal conduit after radical cystectomy is a rare complication.
Case presentation:
A 72-year-old woman underwent laparoscopic radical cystectomy with ileal conduit. After surgery, leakage of ileal-ureteral anastomosis with infection was observed. Five months after surgery, sudden bleeding from the ileal conduit occurred that stopped spontaneously. Contrast-enhanced computed tomography suggested a pseudo aneurysm of the right external iliac artery in contact with the ileal conduit. A fistula between the artery and ileal conduit was suspected. She underwent embolization of the common iliac artery and femorofemoral bypass. She had a good clinical course and no sign of hematuria over 6 months of follow-up.
Conclusion:
An episode of warning hemorrhage from the urostomy is an important sign of fistula, and endovascular treatment is a feasible approach to treat this condition.
