Characterisation of aorto-iliac arterial stenoses in terms of pressure and flow

Aorto-iliac stenoses were characterised in terms of pressure drop and flow velocity in a canine model and in patients with occlusive arterial disease. Pressure above and below the stenosis was measured intra-arterially and flow related measurements were made at rest and during reactive hyperaemia in...

Description
Summary:Aorto-iliac stenoses were characterised in terms of pressure drop and flow velocity in a canine model and in patients with occlusive arterial disease. Pressure above and below the stenosis was measured intra-arterially and flow related measurements were made at rest and during reactive hyperaemia in the dog, and following papaverine administration in patients. The addition of flow velocity information to the pressure drop across a stenosis gave an increased separation of stenoses in the experimental animal and also in man.
