Abstract
Anatomical diversity is rather typical in the biliary region. However, it has only sometimes been documented that the arteries of a hepatobiliary origin compressed the extrahepatic bile duct. Biliary obstruction may be caused by a myriad of benign and malignant diseases. Right hepatic artery syndrome (RHAS) is described as the consequence of right hepatic artery compression of the extrahepatic bile duct. We report a case of a 22-year-old male who presented with a complaint of abdominal pain and was later admitted as a case of acute calculous cholecystitis with obstructive jaundice. Abdominal ultrasound showed a picture of the so-called Mirizzi. However, A magnetic resonance cholangiopancreatography showed a picture of RHAS, so the patient needed endoscopic retrograde cholangiopancreatography to decompress the biliary system which was later performed successfully followed by cholecystectomy. The diagnosis of RHAS is well established in the literature, and it depends on the facility of the institute, cholecystectomy versus hepaticojejunostomy or endoscopic treatment alone are the management options that have been utilized to manage such cases.
