A 69-year-old man was transferred to our hospital for massive hemorrhage from a right hepatic artery pseudoaneurysm 5 months after surgery for gastric cancer. Stent-graft placement was planned to avoid fatal hepatic infarction, and a guiding sheath was advanced deeply into the tortuous and stenotic right hepatic artery beyond the pseudoaneurysm for safe deployment of a stent-graft. However, this advancement caused arterial dissection of the right hepatic artery. After the guiding sheath was pulled back, a Viabahn stent-graft was successfully advanced over a guidewire to exclude the pseudoaneurysm. We consider that a Viabahn stent-graft is more flexible than a guiding sheath and that advancing a Viabahn stent-graft directly from a proximally...
