DRAGON: International registry for patients who had combined portal and hepatic vein embolization before liver surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The DRAGON Registry is an international, multicenter observational database that retrospectively and prospectively collects clinical and imaging data from patients who underwent combined portal and hepatic vein embolization prior to liver surgery. It aims to identify associations between baseline characteristics, imaging findings, and safety with post-procedure outcomes. The study does not assign any treatment; instead it observes real-world use of PVE/HVE and tracks complications, liver regeneration, and subsequent surgical results. Data are gathered from participating centers to help better understand which patients may benefit from this approach and how it influences future liver remnant and resection planning.
