Comprehensive review of TIPS technical complications and how to avoid them

Abstract

Objective: The goal of this article is to describe potential technical complications related to transjugular intrahepatic portosystemic shunts (TIPS) placement and to discuss strategies to avoid and manage complications if they arise.

Conclusion: TIPS is an established interventional therapy for complications of portal hypertension. Although TIPS remains a relatively safe procedure, direct procedure-related morbidity rates are as high as 20%. The technical complexity of this intervention increases the risk for methodologic mishaps during all phases of TIPS placement, including venous access and imaging, transhepatic needle puncture, shunt insertion, and variceal embolization. Thus, interventional radiologists require a thorough stepwise understanding of TIPS insertion, possible adverse sequela, and technical tips and tricks to maximize the safety of this procedure.
