Optimization stages of transjugular intrahepatic portosystemic shunt technique as a treatment method for portal hypertension complications

Aim. To describe the milestones to optimize of the technique of transjugular intrahepatic portosystemic shunt. Materials and methods. The PubMed and Embase databases, the Web of Science platform, the Google Scholar retrieval system, the Cochrane Database of Systematic Reviews, the eLIBRARY.RU scientific electronic library, and the reference lists were used to search for articles. Articles corresponding to the aim of the review were selected for 1969-2023. The inclusion criteria were limited to technical solutions related to optimize of the technique of transjugular intrahepatic portosystemic shunt. Results. Innovative ideas, subsequent experimental studies and preliminary experience in liver cirrhosis patients contributed to the introduction of transjugular intrahepatic portosystemic shunt into clinical practice. At the moment, the main achievement to optimize of the technique of transjugular intrahepatic portosystemic shunt is progress in the qualitative characteristics of stents. The transition from bare metal stents to expandable polytetrafluoroethylene-covered stent graft made it possible to largely prevent shunt dysfunction. However, the issue of its optimal diameter, contributing to an effective reduction of portal pressure without the risk of developing hepatic encephalopathy, which is one of the most common complications of transjugular intrahepatic portosystemic shunt, remains relevant. Conclusion. Further to optimize of the technique of transjugular intrahepatic portosystemic shunt, as well as careful selection of patients based on cognitive indicators, nutritional status and assessment of liver function will reduce the incidence of hepatic encephalopathy and improve treatment results.
