[New puncture technique for TIPSS (transjugular intrahepatic portosystemic stent shunt)].
To establish a safer puncture method for TIPSS (Transjugular Intrahepatic Portosystemic Stent Shunt), we developed a new percutaneous puncture technique to penetrate portal and hepatic vein trans-hepatically under ultrasonography (US technique). Experimentally we compared this technique with conventional transjugular technique puncturing portal vein through hepatic vein using Ross needle (Ross Needle technique). Success rate is 100% in US technique and 50% in Ross needle technique. Seven complication including intraperitoneal bleeding occurred in Ross needle technique, but no complication in US technique. Conclusively, US technique is a safer and more reliable method than that using Ross needle in the puncture method for TIPSS.
