Brain aneurysm showdown: which procedure is safer?

NCT ID NCT07707076

First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time

Summary

This trial compares two endovascular procedures for treating unruptured wide-neck brain aneurysms: a flow diverter device (Pipeline) versus traditional stent-assisted coiling. About 266 adults aged 18–75 with these aneurysms will be randomly assigned to one treatment and followed for up to 5 years. The goal is to see which approach has fewer complications like stroke or death, and which leads to better long-term aneurysm closure.

What this could mean

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

Active substance
a flow diverter device (Pipeline) or a stent-assisted coiling procedure
What this could lead to
If one approach proves safer and more effective, it could become the preferred treatment for these hard-to-treat brain aneurysms, reducing stroke risk and improving long-term outcomes.
What could go wrong
This is a randomized trial, but results may not apply to all aneurysm types or patients. Both procedures carry risks like stroke or vessel damage, and long-term benefits are still being studied.
