dc.description.abstract Currently , size is used as the predetermining factor to judge whether a saccular aneurysm is likely to rupture . Recent studies of the nonlinear mechanics of saccular aneurysms suggest that it is unlikely that they enlarge or rupture via material (limit point ) or dynamic (resonance ) instabilities . Rather , there is a growing body of evidence from both vascular biology and finite element analyses that implicate mechanosensitive growth and remodeling processes . There is , therefore , an even greater need to quantify regional multiaxial wall stresses , which because of the membrane -like behavior of aneurysms implicates the need for better data on regional surface curvatures . By using a convenient function , such as a Legendre polynomial , a quick , accurate approximation can be made for the size and shape of a saccular aneurysm that allows for stress analysis that surgeons can use to determine if the risk of rupture warrants the risk of treatment . en_US
