Post-hepatectomy liver insufficiency is one of the most serious complications in patients undergoing major hepatic resection. Preoperative portal vein embolization is performed with the aim of inducing hypertrophy of the future liver remnant and is thought to reduce the risk of liver insufficiency after hepatectomy. We, interventional radiologists, are required to safely complete the procedure to promote future liver remnant hypertrophy as possible and understand portal vein anatomy variations and hemodynamics, embolization techniques, and how to deal with possible complications.

In the early days of TIPS, complications included the poor long-term patency of the stent and a high incidence of hepatic encephalopathy. In addition, an excessive shunt diameter after TIPS often resulted in severe hepatic encephalopathy.
