Acute heparin-induced thrombocytopenia (HIT) without thrombocytopenia post aortocoronary bypass grafting.

Heparin-induced thrombocytopenia (HIT) after cardiac surgery is a clinical condition associated with increased incidence of thromboembolic events and mortality. HIT without thrombocytopenia is a rare clinical entity poorly reported in the literature, especially after cardiac surgery. In this case report, we present the case of a post aortocoronary bypass grafting patient who presented with HIT in the absence of thrombocytopenia.
