Two patients are presented in whom cerebral angiography was complicated by bioccipital infarcts resulting in cortical blindness with persisting severe restriction of the visual field (case 1) and persisting cortical blindness (case 2). One patient (case 1) demonstrated a compensated, protracted disseminated intravascular coagulation (Table 1), which disappeared after treatment with phenprocoumon (Marcoumar). The other patient (case 2) demonstrated increasee spontaneous platelet aggregability (Table 2), which was treated sucessfully with acetylsalicylic acid (Magnyl) and dipyridamole (Persantine). We presume that the coagulation disturbances demonstrated after the angiography may be pathogenetic to the complications. We propose that patients with transient cerebral ischemia and apoplexy who are undergoing cerebral angiography should be studied with regard to coagulation before and after the cerebral angiography so that coagulation disturbances demonstrated may be treated before, or corrected after the angiography.
本文报告了2例患者，他们在进行脑血管造影时并发双侧枕叶梗死，导致皮质盲，其中1例（病例1）视野严重受限且持续存在，另1例（病例2）则持续存在皮质盲。1例患者（病例1）表现为代偿性、迁延性弥散性血管内凝血（表1），使用苯丙香豆素（Marcoumar）治疗后消失。另1例患者（病例2）表现为自发性血小板聚集性增加（表2），使用阿司匹林（Magnyl）和双嘧达莫（Persantine）成功治疗。我们推测血管造影后出现的凝血障碍可能是并发症的发病原因。我们建议，对于正在接受脑血管造影的短暂性脑缺血和中风患者，应在血管造影前后研究其凝血情况，以便在血管造影前对已发现的凝血障碍进行治疗，或在血管造影后进行纠正。
