Core Tip

Core Tip: Non-tumoral portal vein thrombosis (PVT) is a common but serious challenge in liver transplant candidates. It significantly affects postoperative outcomes, especially in advanced cases. A multidisciplinary approach is crucial for the management of PVT. Integrating anticoagulation, interventional radiology, and intraoperative strategies that are tailored to PVT severity is paramount. While early PVT cases can be managed with thrombectomy and portal vein reconstruction, complex cases may require alternative surgical techniques. This manuscript provides a comprehensive analysis of PVT management in patients requiring liver transplant by emphasizing evidence-based strategies and presenting our institutional protocol to optimize outcomes in this high-risk population.
