Autopsy image of a percutaneous biliary catheter in the portal vein. The biliary drain placement was performed to relieve a biliary stricture but the catheter was placed in the portal vein adjacent to the targeted bile duct resulting in hemoperitoneum. The end of the catheter was cut during removal of the liver as this was an unexpected finding at autopsy.
