Between 1973 and 1978 spontaneous lysis of obstructions in an external cerebral artery was detected in seven out of 3500 patients who suffered from symptoms of cerebrovascular failure in the territory of the internal carotid or vertebral artery. All patients underwent our routine cerebrovascular Doppler ultrasound examination. In the seven patients a high grade obstruction in the internal carotid artery (six cases) or in the brachiocephalic trunk (one case) was found by Doppler and/or angiography 1-3 days after the onset of the symptoms. On a second examination 4-30 days later these obstructions were no longer present either in the Doppler examination and on the angiograms, or in the surgically exposed vessel. These findings suggest that spontaneous lysis of the obstructions must have occurred. Furthermore vascular surgery should not be delayed more than 3-7 days without another reliable vascular examination.
1973年至1978年间，在3500例出现颈内动脉或椎动脉供血区脑血管功能衰竭症状的患者中，有7例被检测到大脑外动脉阻塞出现自发溶解。所有患者均接受了我们常规的脑血管多普勒超声检查。在这7例患者中，症状出现后1至3天，通过多普勒检查和（或）血管造影发现颈内动脉（6例）或头臂干（1例）存在高度阻塞。在4至30天后的第二次检查中，无论是多普勒检查、血管造影，还是手术暴露的血管中，这些阻塞均已不复存在。这些发现表明阻塞肯定发生了自发溶解。此外，在没有进行其他可靠血管检查的情况下，血管手术不应延迟超过3至7天。
