title: [After-care of TIPSS patients. Comparison between color Doppler ultrasound and portography].
abstract: OBJECTIVE
  Comparison of color Doppler sonography and venous portography in patients with a transjugular intrahepatic portosystemic stent shunt (TIPSS).
  
  
  METHODS
  In a prospective study 40 consecutive patients with TIPSS underwent venous portography and color Doppler sonography on the same day as follow-up. Shunt velocities were recorded within the TIPSS at the proximal (hepatic vein segment) and distal part (portal vein segment).
  
  
  RESULTS
  In 28 patients with functioning TIPSS the mean shunt velocity ranged between 30 and 120 cm/s (median 60 cm/s) at the portal vein segment and between 60 and 155 cm/s (median 82 cm/s) at the hepatic vein segment. There was a significant increase of the mean shunt velocity in the hepatic vein segment (P < 0.001). In 12 patients with compromised TIPSS the mean shunt velocity was reduced to 26 +/- 7 cm/s at the portal venous end (P < 0.0001).
  
  
  CONCLUSIONS
  Because of an accelerated shunt velocity in the hepatic vein segment a site-specific evaluation of both TIPSS endings is necessary with color Doppler sonography. In compromised TIPSS the shunt velocity is reduced at the portal venous end. Color Doppler sonography is a valid non-invasive means for follow-up of patients with TIPSS.
