Abstract
Flow-diverting (FD) stents represent a new concept in the treatment of intracranial aneurysms with challenging anatomical dispositions. Having been introduced to clinical practice only in the last 5 years and featuring complex mechanisms of action, they are still under research. Scanning electron microscopy, as part of an animal research protocol, provides detailed surface observations of neointimal healing at the aneurysm's neck, as well as covered side branch ostia, allowing for the confirmation of scientific hypotheses and observations. Technical adaptations of preparation protocols are presented based on a pilot study on Large White pigs, stented with FD stents at carotid bifurcations.
