Abstract

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 × 10/µL, but improved spontaneously to 210 × 10/µL after 8 days. In conclusion, physicians should be aware of this complication, particularly when dual antiplatelet therapy is being considered.

摘要

对比剂诱导的血小板减少症是一种罕见的并发症，其特征为急性和严重的血小板消耗，并在数天内自发恢复。我们描述了一例冠状动脉血管成形术后6小时出现急性血小板减少症的病例，该患者抗血小板因子4检测呈阴性。血小板计数降至1×10/µL，但8天后自发升至210×10/µL。总之，医生应意识到这种并发症，尤其是在考虑双重抗血小板治疗时。
