Three-Dimensional Portal Vein Geometry Predicts Post-TIPS Hepatic Encephalopathy and Variceal Rebleeding: A Multicenter Study
Simple 3D scans of liver blood vessels before a procedure can now predict which cirrhosis patients will develop serious complications, improving surgical planning.
In 579 cirrhotic patients undergoing TIPS, preoperative 3D CT-derived portal vein geometry (bifurcation angles and vessel tortuosity) independently predicted 1-year hepatic encephalopathy and variceal rebleeding, with integrated models substantially outperforming clinical-only prediction. This non-invasive imaging biomarker approach may support patient selection and procedural planning for TIPS.

Why it surfaced
Novel 3D imaging biomarker validated in multicenter cohort; C-index improvement is clinically meaningful; routine CT data already available pre-procedure. Off-core-watchlist (liver disease not primary focus) limits score to 5.
