From: Viabahn stent graft for arterial injury management: safety, technical success, and long-term outcome
Viabahn stent graft for endovascular treatment of uretero-iliacal fistula. In an 80-year-old male patient with a complex medical history, including extensive prior surgery and chemotherapy for colon carcinoma, multiple prior surgeries for urolithiasis, and ureteric stent implantation, the removal of the ureteric stent led to massive hematuria. A Subsequent ureterorenoscopy revealed the presence of a fistulous connection between the left ureter and the adjacent left internal iliac artery (red arrows), B which was first addressed through coiling. C Due to residual perfusion (orange arrows), D a Viabahn stent graft was deployed. E Ureterography showed no remaining perfusion of the fistula. F Final target site angiography demonstrated preserved left iliac blood flow
