Congenital extrahepatic portosystemic shunt: an underdiagnosed but treatable cause of hepatopulmonary syndrome
2016
Congenital extrahepatic portosystemic shunt (CEPS) is a rare malformation of the mesenteric vasculature, which may lead to severe complications. In this report, we describe a case series of three children with type II CEPS (presenting as hypoxemia) and hepatopulmonary syndrome (HPS). The first patient was a 4-year-old male who did not receive any specific treatment and subsequently died of brain abscess 5 years after the diagnosis. The second patient was a 10-year-old female with a 5-year history of cyanosis and dyspnea on exertion. She had partial regression of hypoxemia and improved exercise tolerance at 8 months after a surgical shunt closure. The third patient was a 4-year-old male with a 3-year history of cyanosis and decreased exercise tolerance. He had full regression of hypoxemia at 3 months after a transcatheter shunt closure.
