Stent Migration and Management: Complication of Hepatovascular Interventional Procedures

Introduction: Stent migration is a relatively uncommon complication during hepatovascular interventions such as transjugular intrahepatic portosystemic shunt placement and hepatic vein recanalization. However, due to the risk of central embolization to critical structures including the inferior vena cava, right atrium, right ventricle, and pulmonary artery, stent migration can result in life-threatening consequences if not managed urgently. This exhibit will discuss technical challenges of stent placement during hepatovascular interventions, complications of stent malpositioning, stent retrieval techniques, and examples of stent migration outcomes.

Content Organization:

1. Discuss technical challenges of stent placement during hepatovascular interventional procedures.

2. Practical solutions for stent misplacement, recoil, and migration.

3. Different techniques of stent retrieval and repositioning.

Learning Points: Stent migration is a potentially fatal complication during hepatovascular interventional procedures. Knowledge and technical adeptness to perform a variety of stent retrieval techniques are indispensable in mitigating irreversible adverse events.
