Persistent neonatal cholestasis and biopsy-proven biliary atresia in a 1.5-month-old boy. US shows the triangular cord sign (arrow in a) and increased diameter of the hepatic artery (27 mm, arrow in b)
  • Evaluate for other causes of neonatal jaundice, liver failure
  • Assess for complications of liver disease (e.g. coagulopathy)
  • RUQ US to screen for other abnormalities (though cannot definitively diagnose biliary atresia[1])
  • Definitive diagnosis made by biopsy or surgical pathology
