Percutaneous transhepatic cholangiography (PTC) was performed on a 23-year-old male because of an atypical progression of hepatitis B antigen-negative hepatitis. No bile duct was entered and the procedure was uneventful. However, celiac angiography the day following PTC revealed abnormal liver vessels in the target area and the patient developed hemobilia and clinical pancreatitis, causing common duct obstruction. Symptomatology persisted until celiotomy 32 days after PTC. Clots were found obstructing the common bile duct.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44383/1/10620_2005_Article_BF01071178.pd
