Measuring blood flow during liver embolization procedures

qDSA Blood Flow Measurement in Patients Undergoing Transarterial Embolization (TAE) of the Liver

Not applicable Interventional University of Wisconsin, Madison · NCT06971991

This study is testing a new method to measure blood flow in patients getting liver embolization to see if it helps make treatments for liver tumors more effective.

What this trial studies

This research evaluates a new technique called quantitative digital subtraction angiography (qDSA) to measure blood flow in patients undergoing liver embolization procedures. The goal is to ensure that the blood flow to liver tumors is effectively reduced by calculating blood flow before, during, and after the embolization. Up to 20 participants will be enrolled for a single study visit, with data collection extending for up to six months. This innovative approach aims to enhance the precision of liver cancer treatments.

Who should consider this trial

Good fit: Ideal candidates for this study are patients scheduled for transarterial embolization of liver tumors who can provide informed consent.

Not a fit: Patients who are pregnant, breastfeeding, or have severe kidney issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this technique could improve the effectiveness of liver cancer treatments by ensuring optimal blood flow reduction to tumors.

How similar studies have performed: While this approach is innovative, similar studies using advanced imaging techniques have shown promise in improving treatment outcomes.
