Which sonographic finding is associated with normal postprocedural Doppler of a transjugular intrahepatic portosystemic shunt (TIPS)?
After successful TIPS placement, the intrahepatic portal venous branches continue to exhibit hepatopetal (toward the liver) flow, while the stent itself shows continuous, relatively high-velocity monophasic flow. Hepatofugal flow in intrahepatic branches may indicate shunt dysfunction.
According to Zwiebel's Introduction to Vascular Ultrasound:
''Normal post-TIPS Doppler shows hepatopetal flow in the intrahepatic portal veins and continuous high-velocity flow within the stent.''
