[Morphologic and informatic study of human femoral artery stenoses for its application as a diagnostic complement].
This paper studies the performance of the blood flow starting from stenotic human adult femoral arteries with different grades of obstruction, removed from autopsies and surgical amputations, and from simulations produced by an original simulator computerized software based on the method of finite elements for newtonian, homogeneous and uncompressible fluids. Its employment generated numerous maximal curves, subsequently joined in a unique graphic of easy application. Exceeding the evaluation of the origin and impact of turbulences by analyzing the different variables involved in such anomalous conditions (i.e: pressure, velocity field and stress tensor), the results here reported may constitute a useful complementary diagnostic method together the others used at present.
