RT Journal Article SR Electronic T1 Anomalous subaortic position of the brachiocephalic vein (innominate vein): an echocardiographic study. JF British Heart Journal JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP 385 OP 387 DO 10.1136/hrt.64.6.385 VO 64 IS 6 A1 J Y Choi A1 M J Jung A1 Y H Kim A1 C I Noh A1 Y S Yun YR 1990 UL http://heart.bmj.com/content/64/6/385.abstract AB 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.
