PURPOSE To evaluate the accuracy of Doppler ultrasonography (US) in determination of patency and detection of stenosis in transjugular intrahepatic portosystemic shunts (TIPS). MATERIALS AND METHODS Retrospective review was performed of 251 Doppler sonograms obtained in 79 patients who underwent TIPS placement. Sonograms were evaluated for (a) the presence of a spectral waveform or color flow signal within the shunt, (b) the maximum peak flow velocity (Vmax) measured at the midportion of the… CONTINUE READING
