A 92-year-old woman with gallstone pancreatitis and acute cholangitis was admitted to our hospital where endoscopic retrograde cholangiopancreatography was performed for emergency biliary drainage. Biliary cannulation was unsuccessful. Consequently, percutaneous transhepatic gallbladder drainage (PTGBD) was performed, and her symptoms improved. The PTGBD tube was removed by the patient on the third day of admission resulting in cardiopulmonary arrest two hours later. Cardiopulmonary resuscitation restored spontaneous circulation. Contrast computed tomography revealed intra-abdominal hemorrhage from the right hepatic artery by the removed part of the PTGBD tube. The patient died despite hemostasis by transcatheter artery embolization. PTGBD is generally effective and safe;however, it can cause fatal hemorrhage, especially if PTGBD tubes are removed by the patient. Thus, self-removal should be strictly prevented.
