  • Title: Doppler ultrasound evaluation of transjugular intrahepatic portosystemic shunt function: pitfalls and artifacts.
    Author: Wachsberg RH.
    Journal: Ultrasound Q; 2003 Sep; 19(3):139-48. PubMed ID: 14571161.
    Abstract:
    The current literature reflects controversy regarding the accuracy of Doppler ultrasound for the detection of transjugular intrahepatic portosystemic shunt (TIPS) malfunction. Experience has revealed many pitfalls and artifacts that can potentially interfere with the proper performance and interpretation of Doppler studies in patients with TIPS. In this article the author discusses and illustrates the spectrum of pitfalls that may be encountered during Doppler evaluation of TIPS function.
