Heparin-associated priapism

Postgrad Med J. 1983 May;59(691):332-3. doi: 10.1136/pgmj.59.691.332.


A patient who developed priapism 7 hr after stopping an intravenous heparin infusion is described. Abnormal spontaneous platelet aggregation was demonstrated whilst on heparin treatment and is thought to play a role in the aetiology of heparin induced priapism.
