Serial cerebral blood flow studies performed by the intra-carotid 133Xenon method were fortuitously determined during the course of a cluster headache in a 32 year old man. The initial study was performed about 10 min after the headache began and showed values at the upper limit of normal. Twenty min after the headache started a second procedure showed that the autoregulatory response on hyperventilation was normal. Ergotamine tartrate was given intra-muscularly 23 min after the headache began and there was partial relief. A third cerebral blood flow estimation showed abnormally high values. The probable reasons for this are discussed.
通过颈内注射氙-133 方法对一名 32 岁男性丛集性头痛发作期间进行的连续脑血流量研究是偶然确定的。首次研究在头痛开始约 10 分钟后进行，结果显示值在正常上限。头痛开始 20 分钟后进行的第二次检查表明，过度通气时的自动调节反应正常。头痛开始 23 分钟后肌肉注射酒石酸麦角胺，疼痛部分缓解。第三次脑血流量估计显示值异常高。文中讨论了出现这种情况的可能原因。
