Obstructive Jaundice Due to Hilar Bile Duct Compression with Encasement of the Right Hepatic Artery

چکیده
A 68-year-old woman had a solitary 12.0 cm hepatic cyst with a septum. The cyst was located near the hepatic hilum and she presented with obstructive jaundice caused by compression of the hilar bile duct. Stenosis of the common hepatic duct was detected at the porta hepatis on endoscopic retrograde cholangiography (ERC), and encasement of the right hepatic artery at the same level was revealed by abdominal angiography. Transpapillary cholangioscopy showed compression and mucosal erosions of the hilar bile duct. After transpapillary cholangioscopy, the hepatic cyst became infected, for which emergency percutaneous transhepatic drainage was performed. As a result, the patient's obstructive jaundice subsided. The mucosal erosions of the bile duct that existed at a site corresponding to the encasement of the right hepatic artery also improved. In conclusion, bile duct stenosis was considered to be caused by compression due to the hepatic cyst and the right hepatic artery.

Obstructive jaundice by vascular compression is extremely rare. Luttwak and Schwartz first described jaundice due to an obstruction of the common hepatic duct by an aberrant artery.1 Compression of extrahepatic bile duct (EBD) by right hepatic artery was defined as right hepatic artery syndrome. We present here a rare case of asymptomatic biliary obstruction due to compression of the common bil...

Endoscopic biliary drainage (EBD) for hepatic hilar obstruction is sometimes challenging. Moreover, when unilateral biliary drainage has already been performed, if another intrahepatic bile duct also needs to be drained, EBDmay be mademore difficult because of tumor ingrowth and the narrowed angle from which the bile duct must be accessed. In this case, percutaneous biliary drainage (PTBD) or e...

Hemangioma is the most common benign tumor of the liver. Liver hemangioma (LH) usually remains asymptomatic, but the most common symptoms associated with LH are abdominal pain and discomfort. LH is an uncommon cause of bile duct dilatation and obstructive jaundice. An 83-year-old Japanese woman who received hemodialysis at another hospital was referred to our hospital because of abnormal liver ...
