Abstract
Transjugular intrahepatic portosystemic shunt (TIPS) is one of the most technically complex procedures in interventional radiology, the need to connect two veins with variable anatomy, located in two different planes in hard and many times small cirrhotic livers using a needle, can be quite challenging. Despite more than 30 years of performing TIPS, the complex hemodynamics of the portal system are not fully understood, and sometimes unpredictable alterations of the portal flow can lead to serious unexpected complications. The best strategies to prevent TIPS complications are optimal patient selection, meticulous technique, operator experience, and immediate correction of identified adverse events. The purpose of this article is to review the technical complications with TIPS, the unique complications related to the use of stent grafts, and the late complications after the procedure, with emphasis on ways to prevent and treat them.
