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. ...
