Determination of the Tangential Elastic Modulus of Human Arteries In Vivo

  • Y. Summa

Abstract

Most of the determinations of the elasticity of the arterial wall are performed on excised arteries in vitro. This is done for the following reasons:
  1. 1.

    The parameters relevant to the calculation of the elastic modulus, e.g., wall thickness, wall radius, or transmural pressure, can be measured much easier in vitro than in vivo.

     
  2. 2.

    In vitro, all parameters can be adjusted easily and varied at will so that it is possible to study the elastic behavior of arteries over wide ranges of pressure and diameter.

     
  3. 3.

    To date, it has been possible to separate the elastic and the viscous behavior of arteries experimentally only in vitro.
