Echo Rounds: Intraoperative Doppler Assessment of Transjugular Intrahepatic Shunt Flow Using Transesophageal Echocardiography.

The use of intraoperative transesophageal echocardiography (TEE) to assess venous congestion of the liver due to right heart dysfunction is well established, predominately through the Doppler interrogation of the hepatic and portal venous waveforms. Transjugular intrahepatic portosystemic shunts (TIPSs) are artificial intraparenchymal tracts through the liver that are placed to decompress the portal circulation in the setting of portal hypertension, most commonly due to cirrhosis. Herein, we describe the Doppler interrogation of a TIPS using intraoperative TEE, and how changes in the transmitted portal venous waveform were used to assess the severity of tricuspid regurgitation and inform management.
