Dye test may reveal hidden blood flow after filler mishaps
NCT ID NCT07581652
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether indocyanine green angiography (ICGA), a dye-based imaging test, can help doctors assess blood flow in the face after a rare but serious complication from hyaluronic acid filler injections. Researchers reviewed medical records and images from 19 patients who had already received treatment for a blocked artery. The goal was to see if ICGA could provide real-time information on tissue perfusion and help predict recovery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- indocyanine green angiography (ICGA)
- What this could lead to
- If successful, this could show that ICGA is a useful tool for doctors to quickly see how well blood flow is returning after treatment for a blocked artery from filler injections.
- What could go wrong
- This is a very small, retrospective study (19 people) that only looks back at existing data. It cannot prove that ICGA improves patient outcomes, only that it might be helpful for assessment.
