title: Peritoneal bleeding due to percutaneous transhepatic gallbladder drainage: An autopsy report.
abstract: A 77-year-old man underwent percutaneous transhepatic gallbladder drainage (PTGBD) for acute cholecystitis as a preoperative procedure; however, he suddenly suffered cardiopulmonary arrest 4 h after the PTGBD and died. There were three centesis scars for the PTGBD, and only one pathway from the most dorsal centesis scar reached the gallbladder. Microscopically, the PTGBD pathway crossed and injured the intrahepatic arterial wall, and hepatic parenchymal bleeding extended along the PTGBD pathway to the inferior surface of the liver. Blood flowed to the peritoneal cavity through a small gap between the liver and gallbladder. Consequently, the PTGBD caused lethal bleeding. When the percutaneous transhepatic cholangio drainage/PTGBD pathway runs close to vessels near the liver surface, it might be necessary to deal with the possibility of rapid and lethal peritoneal bleeding.
