A transjugular intrahepatic portosystemic shunt (TIPS) is a tract created within the liver using x-ray guidance to connect two veins within the liver. Transjugular intrahepatic portosystemic shunt was very effective in decreasing the portosystemic pressure gradient from 26.2 +/ -5.8 to 10 +/-6.2 mmHg. During the past decade, transjugular intrahepatic portosystemic shunting (TIPS) has become accepted as an alternative to the surgical shunt procedure for controlling the complications of portal hypertension, yet few data exist regarding infectious complications. 69 0 obj <>stream All patients underwent a TIPS procedure in order to maintain the patency of the portal vein by facilitating the outflow.

TIPS placement reduces elevated portal pressure by creating a low-resistance channel between the hepatic vein and an intrahepatic branch of the portal vein using angiographic techniques ( figure 1 and image 1 ). Transjugular Intrahepatic Portosystemic Shunt (TIPS) is a radiological procedure used to control bleeding from portal hypertension when nonsurgical interventions have failed. 's article entitled “A Case‐Controlled Study of the Safety and Efficacy of Transjugular Intrahepatic Portosystemic Shunts After Liver Transplantation.” 1 We published the outcomes for 26 patients who underwent transjugular intrahepatic portosystemic shunt (TIPS) placement for intractable ascites after liver transplantation. Indications for TIPS determined by controlled trials include management of variceal bleeding, refractory cirrhotic ascites, hepatorenal syndrome, 51 INTRODUCTION. During the TIPS procedure, a channel, which shunts blood from the portal vein to a hepatic vein, is created through the hepatic parenchyma, reducing the portosystemic pressure gradient.
