What is TIPSS surgery: TIPSS surgery, known as transjugular intrahepatic portosystemic stent shunt, is a surgical technique developed in recent years and gradually matured for the treatment of portal hypertension, ruptured bleeding esophagogastric varices and intractable ascites in cirrhosis.TIPSS surgery is successful, portal blood flow can be rapidly reduced and portal hypertension can be immediately relieved, and its efficacy has been The efficacy of TIPSS has been widely affirmed by scholars at home and abroad. The efficacy of TIPSS has been widely recognized by domestic and foreign scholars. 1, portal hypertension with ruptured bleeding of gastroesophageal varices (including acute hemorrhage). 2.Recurrent ruptured variceal bleeding and ineffective by medical treatment. 3, portal hypertension causing intractable ascites. 4.Buga’s syndrome combined with portal hypertension. 5.Transitional treatment before liver transplantation. The procedure uses an interventional method to puncture the catheter, firstly, percutaneously into the internal jugular vein, then, sequentially into the superior vena cava, right atrium, inferior vena cava and hepatic vein, through the puncture catheter, a fine needle is inserted and the liver parenchyma is punctured to establish a channel between the hepatic vein and portal vein, which is kept open by an expandable metal stent. To use a figurative analogy, portal hypertension is like a river whose water level has risen so high that it is already at risk of breaking, while the TIPSS procedure is like creating a diversion channel to the river, which can understandably lower the water level and avoid the breakthrough. Advantages of the surgery] This surgery has the advantages of less trauma, shorter operation time, slight damage to liver function, easy control of portal shunt flow, less complications, less influence by the degree of liver function, and faster recovery of patients after the surgery.
