Rupture of an abdominal aortic aneurysm (AAA) is a significant cause of mortality in the United States. Often asymptomatic, AAA is considered a silent killer because it frequently remains undiagnosed until the time of rupture or the patient's death. Major risk factors, such as smoking, age, sex, race, and family ...

Cerebral aneurysms form preferentially at arterial bifurcations. The vascular optimality principle (VOP) decrees that minimal energy loss across bifurcations requires optimal caliber control between radii of parent (r0) and daughter branches (r1 and r2): r0(n)=r1(n)+r2(n), with n approximating three. VOP entails constant wall shear stress (WSS), an endothelial phenotype regulator. ...
