Is it better to treat aneurysms with two overlapping flow diverters, or one compressed diverter? A computational study published in the American Journal of Neuroradiology points to the single, compressed diverter provided that it produces a mesh denser than the two overlapped diverters, and that it covers at least half of the aneurysm opening. The ongoing research could eventually help doctors determine the best way to treat patients suffering from aneurysms.
