Contrast-induced thrombocytopenia following percutaneous coronary intervention.

Contrast-induced thrombocytopenia is a rare complication distinguished by acute and severe platelet consumption, with spontaneous recovery within days. We describe a case of acute thrombocytopenia 6 hours after coronary angioplasty in a patient with a negative antiplatelet factor 4 test. The count reached 1 × 103/µL, but improved spontaneously to 210 × 103/µL after 8 days. In conclusion, physicians should be aware of this complication, particularly when dual antiplatelet therapy is being considered.
