Flow diverter with or without adjunctive coils in the treatment of large and giant intracranial aneurysms: a meta-analysis.

Summary: Imagine a balloon bulging out of a weak spot in a brain artery. This is called a brain aneurysm. If it gets too big, it can be very dangerous. Doctors often use a tiny mesh tube called a "flow diverter" to block blood from rushing into the balloon, helping it shrink and heal. Sometimes, they also pack the balloon with tiny metal coils to help the process.

A new study looked at whether using both the tube and the coils is better than just using the tube for really big aneurysms. The results? Adding coils didn't make the balloon heal any faster, but it did make the surgery safer by lowering the chance of bad side effects!
