Transjugular Intrahepatic Portosystemic Shunt Procedure

As described previously [12 (link)], TIPS procedure was performed by the same team of experienced radiologists. Briefly, the right internal jugular vein was punctured with RUPS-100 (Cook Inc., Bloomington, USA) puncture device, intubated to the hepatic vein through the vena cava, and the portal vein was punctured under fluoroscopy to establish the direct channel between the hepatic vein and the portal vein. Then, portasystemic shunt was established by balloon expansion (6–8 mm) and stents were placed. A bare Stent (Bard E-LUMINEXX Vascular Stent, Karlsruhe, Germany) followed by a covered Stent (Fluency; Bard Inc., New Jersey, USA or Viabahn; GORE, Newark, USA) were used. During the procedure, portal vein pressure gradient was measured before and after the shunt was established.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
