Predictive model enhances surgical options for liver tumor patients

A predictive model for identifying intrahepatic collateral vessels in patients with caval confluence tumors reveals that 78% exhibited such vessels. Out of those, 92% underwent parenchyma-sparing hepatectomies, with zero operative mortality and no liver congestion reported. The study established tumor size, number, hepatic vein infiltration, and tissue density as key predictors for the presence of these vessels, achieving an 82% discrimination rate. This model could significantly guide surgical strategies and improve resectability.
