Effectiveness of Preoperative Intrahepatic Portal Venous Classification System in Guiding Preoperative Surgical Decisions and Predicting Hypotensive Effects After Meso-rex Bypass for Children With EHPVO

In brief

This study evaluates a portal venous classification system using wedged hepatic venous portography to guide surgical planning for meso-Rex bypass in children with extrahepatic portal vein obstruction. The system helps identify suitable candidates and predict postoperative hypotensive complications, though it remains underutilized in clinical practice despite being available for a decade.

• WHVP-based IHPS classification effectively identifies pediatric EHPVO patients suitable for meso-Rex bypass preoperatively.
• The classification system aids in preoperative Rex recessus evaluation, improving surgical candidate selection.
• Despite being available for a decade, this IHPS classification tool remains clinically underutilized in practice.
• WHVP imaging can predict hypotensive effects post-MRB, enhancing perioperative risk stratification.
• Wider adoption of this classification system could optimize surgical decision-making for pediatric portal hypertension.
