간문맥의 해면상 변형에 의해 발생된 폐쇄성 황달 1예 = A Case of Obstructive Jaundice Caused by Cavernous Transformation of the Portal Vein

다국어 초록 (Multilingual Abstract)

Cavernous transformation of the portal vein is a rare condition probably arising secondary to extrahepatic portal vein thrombosis or obstruction with recannalization and/or collateral veins formation to bypass the obstruction. It is believed that cavernous transformation of the portal vein is caused by a variety of diseases associated with periportal collateral development and hepatopedal flow. It is known that portal vein occlusion, which is the actual cause of cavernous transformation, has a wide variety of etiologies, such as congenital abnormalities, omphalitis, pancreatitis, various carcinoma, and liver cirrhosis. In most cases, the revealing symptom is upper gastrointestinal bleeding. Rarely, however, diagnosis is made from obstructive jaundice. Extensive collateral veins due to portal vein occlusion may compress and narrow the biliary tract. A 39-year-old man was admitted due to jaundice and abdominal discomfort for 1 month. He was confirmed to have obstructive jaundice due to collateral vessels of cavernous transformation of the portal vein. We report a case of obstructive jaundice caused by cavernous transformation of the portal vein.
