A persistent erection marked by rigidity of the corpora cavernosa (CC) and little or no cavernous arterial inflow resulting in progressive hypoxia and acidosis The patient typically reports penile pain after 6 to 8 hours, and the examination reveals a rigid erection. Interventions beyond 48 to 72 hours of onset may help relieve erection and pain but have little benefit in preserving potency After 48 hours thrombus can be found in the sinusoidal spaces, and smooth muscle necrosis – Ischemic priapism is an emergency.
