Introduction: The mathematical modeling of aneurysms has been critical in helping to understand the biophysical phenomena that contribute to aneurysm growth and rupture. Prior studies have demonstrated that complex binary logistic regression models may determine which physical parameters of an aneurysm contribute to aneurysm rupture. Because of the posterior communicating artery (PCoA) aneurysm's high propensity for rupture, we studied and derived a relational equation that describes the rupture potential for PCoA aneurysms within …
