Triangular Cord Sign. Gallbladder length less than 19 mm is suggestive for atretic gallbladder. The combination of the triangular cord sign and gallbladder abnormalities can improve diagnostic sensitivity.
Web triangular cord sign represents the fibrous ductal remnant of the extrahepatic bile duct in biliary atresia. Subcapsular hepatic arterial flow on doppler. Web it has been recently suggested that the triangular cord (tc) sign is a simple and useful tool in the diagnosis of biliary atresia. The diagnostic accuracy was 95%, sensitivity was 93%, and specificity was 96%. The combination of the triangular cord sign and gallbladder abnormalities can improve diagnostic sensitivity. Web the triangular cord sign is a triangular or tubular echogenic cord of fibrous tissue, representing the ductal remnant of the extrahepatic bile duct, seen in the porta hepatis at ultrasonography, and is relatively specific for the diagnosis of biliary atresia 1,2. Represents ductal remnant of extrahepatic bile duct. There are some evidences that triangular cord (tc) sign, i.e., triangular structure located cranial to the portal vein bifurcation on ultrasonographic examination, is suggestive of ba in suspected cases. Web background the triangular cord (tc) sign is the appearance of a triangular shaped echogenic density visualised immediately cranial to the portal vein bifurcation on ultrasonographic examination. Web the triangular cord sign and gallbladder abnormalities are the two most accurate and widely accepted ultrasound characteristics currently used for the diagnosis or exclusion of biliary atresia.
Subcapsular hepatic arterial flow on doppler. The diagnostic accuracy was 95%, sensitivity was 93%, and specificity was 96%. Web the triangular cord sign is a triangular or tubular echogenic cord of fibrous tissue, representing the ductal remnant of the extrahepatic bile duct, seen in the porta hepatis at ultrasonography, and is relatively specific for the diagnosis of biliary atresia 1,2. There are some evidences that triangular cord (tc) sign, i.e., triangular structure located cranial to the portal vein bifurcation on ultrasonographic examination, is suggestive of ba in suspected cases. The combination of the triangular cord sign and gallbladder abnormalities can improve diagnostic sensitivity. Increased echogenicity along the anterior wall of the portal vein, that represents the fibrous ductal remnant of the extrahepatic bile duct. Larger hepatic arterial caliber 2. Subcapsular hepatic arterial flow on doppler. Early detection of biliary atresia (ba) has a vital role in prevention of liver cirrhosis in these patients. Several studies have reported that this ultrasonographic sign is a reliable and helpful marker in identif. Web a triangular cord sign was found in 27 of 29 infants with biliary atresia and in one of 26 infants with neonatal hepatitis or other causes of infantile cholestasis.
