Vascular (Arterial and Venous) Assessment of Erectile Dysfunction

  • Harin Padma-Nathan

Abstract

Vascular assessment in the arena of erectile dysfunction (ED) includes both evaluations of the adequacy of cavernosal arterial inflow and of evaluations of the corporal veno-occlusive mechanism. The hemodynamic demand for arterial inflow in the early phase of an erection is such that inflow increases nearly tenfold from the resting flaccid state. The corporal veno-occlusive mechanism of an erection is an active event critically dependent on the integrity of the corporal trabecular smooth muscle, fibro-elastic skeleton, and lacunar endothelium. Veno-occlusion is effected by the stretching and compression of the subtunical plexus of venules following smooth muscle relaxation.
