Peritoneal bleeding due to percutaneous transhepatic gallbladder drainage: An autopsy report.

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.

In a 64-year-old male patient, liver metastasis recurred after surgery for transverse colon cancer. He received 6 courses of continuous intra-arterial infusion therapy with a catheter for hepatic intra-arterial infusion, which was retained by the GDA-coil technique. In April 2005, the patient suddenly developed hematemesis, and he was hospitalized for emergency treatment.
