Pulse pressure wave analysis in the diagnosis of aorto-iliac disease.

The severity of aorto-iliac disease has been evaluated by direct pressure recording at the time of translumbar aortography. Pulse wave analysis confirmed the radiological appearance of 35 aorto-iliac segments and in one further segment, identified a normal haemodynamic pattern in the presence of marked degenerative disease. The method is safe, accurate, simple and relatively inexpensive.
