A status analysis of the direct intrahepatic portacaval shunt (DIPS) treatment for portal hypertension

Transjugular intrahepatic portosystemic shunt (TIPS) is a surgery which was commonly used in portal hypertension therapy. It can control and prevent the complication caused by portal hypertension, such as esophageal gastric-fundus variceal bleeding. However, there is a fundamental flaw in the TIPS due to its lack of maintaining a long-lasting and effective shunt, and most of the stenosis or occlusion are in the draining vein: the hepatic vein. Accompanied by direct intrahepatic portosystemic shunt (DIPS), which has shown its advantage compared with traditional TIPS operation, such as the block of hepatic vein can be avoided, the radiation dose as well as the operation time is lesser, DIPS is safer and so on. Here we reviewed to present a brief introduction of DIPS development history and core concerns of the major medical centers at present.
