[Intra-aortic balloon pumping and heparin-induced thrombocytopenia].

Thrombocytopenia is frequently reported in the presence of intra-aortic balloon pumping (IABP) after cardiac surgery and in cardiology, but heparin-induced thrombocytopenia (HIT) is rarely responsible of it in this circumstance. A case-report if HIT in a patient with IABP is presented. This case emphasised the difficulty in diagnosis of HIT in this situation. An acute decrease in platelet count lasting after removal of IABP could suggest the diagnosis of HIT when other origins for thrombocytopenia are excluded.
