Vasovagal reactions are the most common type of adverse reaction after blood donation; however, there are no reports of ischemic colitis as an adverse reaction after blood donation. A previously healthy 55-year-old woman suffered loss of consciousness at the end of her first plasma donation. She was diagnosed with a vasovagal reaction and received hydration. However, she developed persistent left flank pain and watery diarrhea, followed by bloody diarrhea. Abdominal computed tomography confirmed ischemic colitis. She was asked to fast and was eventually discharged 7 days later. We should consider the possibility of ischemic colitis if patients develop persistent abdominal pain after transient hypotension, such as that observed during a vasovagal reaction.
血管迷走神经反应是献血后最常见的不良反应类型；然而，尚无缺血性结肠炎作为献血后不良反应的报道。一名既往健康的55岁女性在首次捐献血浆结束时出现意识丧失。她被诊断为血管迷走神经反应并接受了补液治疗。然而，她出现了持续的左侧胁腹疼痛和水样腹泻，随后发展为血便。腹部计算机断层扫描证实为缺血性结肠炎。她被要求禁食，最终在7天后出院。如果患者在短暂性低血压（如血管迷走神经反应期间观察到的）后出现持续性腹痛，我们应考虑缺血性结肠炎的可能性。
