In 24 (0.98%) of 2457 patients with congenital heart disease the brachiocephalic vein was in an anomalous position below the aortic arch. This is a much higher proportion of such cases than reported so far. This high frequency may arise from differences in the study population and the method of diagnosis. This venous anomaly was more common in patients with tetralogy of Fallot or ventricular septal defect with pulmonary atresia. Patients with the venous anomaly were more likely to have a right aortic arch. The anomalous course of the brachiocephalic vein from the neck to the junction of the superior vena cava was shown by cross sectional echocardiography. In doubtful cases, Doppler study usually clarified the anatomical arrangement.
在2457例先天性心脏病患者中，有24例（0.98%）的头臂静脉位置异常，位于主动脉弓下方。这一病例比例远高于迄今为止的报道。这种高频率可能源于研究人群和诊断方法的差异。这种静脉异常在法洛四联症或室间隔缺损合并肺动脉闭锁的患者中更为常见。有静脉异常的患者更有可能有右主动脉弓。经胸超声心动图显示了头臂静脉从颈部到上腔静脉汇合处的异常走行。在可疑病例中，多普勒研究通常能明确解剖结构。
