Anomalous left brachiocephalic vein (BCV) is a rare and less known systemic venous anomaly. We evaluated congenital anomalies of the left BCV in adults detected during computed tomography (CT) examinations.
This retrospective study included 81,425 patients without congenital heart disease who underwent chest CT. We reviewed the recorded reports and CT images for congenital anomalies of the left BCV including aberrant and supernumerary BCVs. The associated congenital aortic anomalies were assessed.
Among 73,407 cases at a university hospital, 22 (16 males, 6 females; mean age, 59 years) with aberrant left BCVs were found using keyword research on recorded reports (0.03%). Among 8018 cases at the branch hospital, 5 (4 males, 1 female; mean age, 67 years) with aberrant left BCVs were found using CT image review (0.062%). There were no significant differences in incidences of aberrant left BCV between the two groups. Two cases had double left BCVs. Eleven cases showed high aortic arches. Two cases had the right aortic arch, one case had an incomplete double aortic arch, and one case was associated with coarctation.
Aberrant left BCV on CT examination in adults was extremely rare. Some cases were associated with aortic arch anomalies.
异常左头臂静脉（BCV）是一种罕见且鲜为人知的体静脉异常。我们评估了在计算机断层扫描（CT）检查中发现的成人左BCV先天性异常。
这项回顾性研究纳入了81425例无先天性心脏病的患者，他们均接受了胸部CT检查。我们查阅了记录报告和CT图像，以查找左BCV的先天性异常，包括异常和多余的BCV。评估了相关的先天性主动脉异常。
在一家大学医院的73407例病例中，通过对记录报告进行关键词搜索，发现22例（16例男性，6例女性；平均年龄59岁）存在异常左BCV（0.03%）。在分院的8018例病例中，通过CT图像复查发现5例（4例男性，1例女性；平均年龄67岁）存在异常左BCV（0.062%）。两组间异常左BCV的发生率无显著差异。2例有双左BCV。11例显示主动脉弓高位。2例有右主动脉弓，1例有不完全双主动脉弓，1例合并缩窄。
成人CT检查中发现的异常左BCV极为罕见。部分病例与主动脉弓异常有关。
