Flow-diverter stents are an exciting addition to treatment armamentarium of intracranial aneurysms.
Often they are used to treat giant, dysplastic or dissecting aneurysms which otherwise are very difficult to treat. These aneurysms, or at least some of them, were treated by 'flow reversal' or 'parent artery sacrifice'. In some of thus treated ones, bleeding occurred, which was hypothesized as to be caused by thombosis induced inflammation and subsequent breakdown of the wall.
This phenomenon was however never conclusively demonstrated.
As a similar phenomenon seems to occur in giant aneurysms treated by flow diverters, demonstration of the inflammation became imperative.
This has been shown by the authors of this particular article.
