Cerebral aneurysm (CA) is a localised dilatation in the wall of the brain vasculature which can cause it to swell out like a balloon. If not treated, it will continue to grow and eventually tear or rupture, resulting in severe disability from stroke and, in around 25% of cases, death [1]. CAs affect up to 5% of the adult population with 1% of detected aneurysms rupture every year [2].
