Introduction: Mathematical modeling of aneurysms is critical in gaining understanding into the biophysical phenomena that contribute to aneurysm growth and rupture. Prior studies have demonstrated certain primary and secondary biomorphometric characteristics which correlate with aneurysm rupture. Aneurysms of the posterior communicating artery (PCoA) have a high propensity for rupture. This study analyzes the relationship between aneurysm rupture status and the angular relationships between the aneurysm, internal carotid (ICA) the …
