Summary

This pilot study aimed to see if blocking a specific artery in the brain could help people with chronic migraines that don't respond to drugs. The procedure, called middle meningeal artery embolization, uses tiny particles or coils to block the vessel. However, the study was withdrawn before enrolling any participants, so no results are available.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Middle meningeal artery embolization (a procedure using particles or coils to block a blood vessel in the brain)
What this could lead to
If it works, this could offer a new treatment option for people with chronic migraines that don't improve with medication.
What could go wrong
This trial was withdrawn before any participants were enrolled, so no data exists. The procedure is invasive and carries risks like bleeding or stroke.
