Efficacy and Safety of Intraparenchymal Portal Vein Covered Stents in Treating Portal Hypertension and Its Complications

The intraparenchymal portal vein covered stent, produced by Shanghai Shenqi Medical Technology Co., Ltd., is used for a transjugular approach. It establishes an artificial shunt between the hepatic vein and the main branches of the portal vein within the liver. This helps in reducing portal venous pressure and alleviating or improving the symptoms of portal hypertension and its complications, such as variceal bleeding, gastropathy, refractory ascites, and/or hepatic hydrothorax.

The GORE® VIATORR® Transjugular Intrahepatic Portosystemic Shunt (TIPS) Covered Stent consists of an implantable covered stent and a percutaneous delivery catheter.
