Brain aneurysm showdown: which treatment is safer and cheaper?
NCT ID NCT01811134
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two procedures for treating unruptured brain aneurysms: traditional coiling (using tiny coils to block blood flow) and a newer method using a flow diverter stent. 91 adults with specific types of aneurysms took part. The goal was to see which treatment works better, is safer, and costs less over time.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- PIPELINE flow diverter stent (device) and detachable coils with or without stent (device)
- What this could lead to
- If successful, this could show that the flow diverter stent is a safe and cost-effective alternative to traditional coiling for certain brain aneurysms.
- What could go wrong
- This is a completed trial with only 91 participants, so results may not apply to all patients. Both procedures carry risks like stroke or bleeding.
