Modeling liver blood flow during surgery

Hepatic and Systemic Hemodynamic Modeling During Liver Surgery

NA · Assistance Publique - Hôpitaux de Paris · NCT05339984

This study is testing a new way to predict blood flow changes during liver surgeries to help doctors choose the right patients and reduce the risk of liver failure after surgery.

What this trial studies

This study aims to develop and validate a mathematical model to predict the evolution of the portocaval gradient during liver surgeries, including partial hepatectomy and liver transplantation. By utilizing hemodynamic modeling, the research seeks to enhance the selection of candidates for liver surgery and anticipate the risk of postoperative liver failure. The approach focuses on three surgical scenarios of increasing complexity, addressing the challenges posed by chronic liver diseases and the need for precise surgical evaluations. The ultimate goal is to improve patient outcomes by minimizing the risks associated with liver surgeries.

Who should consider this trial

Good fit: Ideal candidates for this study are adults with liver diseases requiring minor or major hepatectomy or liver transplantation.

Not a fit: Patients who are pregnant, breastfeeding, or have contraindications to MRI will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the risk of postoperative liver failure and improve survival rates for patients undergoing liver surgery.

How similar studies have performed: While the approach of hemodynamic modeling in liver surgery is innovative, similar studies have shown promise in improving surgical outcomes through advanced predictive tools.
