Repeated CT scans provide the only means of confirming the initial ischemic nature of a cerebrovascular accident and its eventual course towards a hemorrhage. Precise data can be obtained as to the frequency of this complication as a function of factors such as the embolic origin of the infarct or associated anticoagulant therapy. The present case shows that contrast medium, at least in patients receiving anticoagulant treatment, may constitute a risk factor by increasing the possibility of transformation of a pale infarct into a hemorrhagic one. Possible relevant properties of iodized contrast media with respect to this type of complication are considered.
重复CT扫描是确认脑血管意外最初缺血性质及其最终发展为出血过程的唯一手段。可以获得关于这种并发症发生频率的精确数据，该频率是梗死栓子来源或相关抗凝治疗等因素的函数。本病例表明，至少在接受抗凝治疗的患者中，造影剂可能会增加苍白梗死转变为出血性梗死的可能性，从而构成一个危险因素。文中考虑了碘化造影剂对于这类并发症可能的相关特性。
