Acute contrast-induced thrombocytopenia is an unusual complication, and it is a rare event with the use of modern low-osmolarity iodinated contrast medium. There are only a few reports that exist in English literature.
The authors report the case of a 79-year-old male patient with severe, life-threatening thrombocytopenia after administration of intravenous nonionic low-osmolarity contrast medium. His platelet count dropped from 179×10/l to 2×10/l after 1 h of radiocontrast infusion. Which has returned gradually to normal level within days with corticosteroid administration and platelet transfusion.
Iodinated contrast-induced thrombocytopenia is a rare complication with an unknown causative mechanism. There is no definitive treatment for this condition, with corticosteroids being used in most cases. The platelet count normalizes within a few days regardless of any interventions, but supportive treatment is important to avoid any unwanted complications. Further studies are still needed for a better understanding of the exact mechanism of this condition.
急性造影剂诱导的血小板减少是一种不常见的并发症,使用现代低渗性碘化造影剂时这是一种罕见事件。英文文献中仅有少数报道。
作者报告了一例79岁男性患者,静脉注射非离子型低渗性造影剂后出现严重的、危及生命的血小板减少。在注射造影剂1小时后,他的血小板计数从179×10⁹/L降至2×10⁹/L。通过给予皮质类固醇和输注血小板,血小板计数在数天内逐渐恢复至正常水平。
碘化造影剂诱导的血小板减少是一种罕见并发症,其致病机制不明。对于这种情况没有确切的治疗方法,大多数情况下使用皮质类固醇。无论是否进行干预,血小板计数在数天内都会恢复正常,但支持治疗对于避免任何不良并发症很重要。仍需要进一步研究以更好地理解这种情况的确切机制。
