Percutaneous transhepatic biliary drainage (PTBD) is one of the commonly performed biliary interventions. In patients with obstructive jaundice, PTBD may be a lifesaving emergency procedure or may serve as an alternative intervention in patients who fail to undergo endoscopic drainage or those who are too sick to be considered for endoscopic drainage. The key factor in technical and clinical success of PTBD is a thorough preprocedure imaging evaluation.
