肝内胆管右后支PTCD引流不畅：常规超声与ICCEUS诊断对比

After the right posterior branch of the intrahepatic bile duct was placed with PTCD drainage, the biliary drainage was not smooth and the bilirubin did not decrease significantly. Let's take a look. Conventional ultrasound showed that the drainage tube was folded between the abdominal wall and the liver, which caused the biliary drainage obstruction. Does the ICCEUS show that the drainage tube is twisted and distorted between the abdominal wall and the liver, and is not inside the bile duct, which clarifies the reason for the biliary drainage obstruction.
