Anomalous courses of the left innominate vein have rarely been described in anatomical specimens. Investigative techniques such as angiography and echocardiography have brought to light more instances of this anomaly. Three more cases identified by anatomical study are described. Earlier cases were reviewed to assess the type of associated cardiac malformations. Clinically, the abnormality is regarded as benign. When it is recognised during investigation it should alert the clinician to the possibility of associated malformations. Features commonly seen in tetralogy of Fallot--right aortic arch, ventricular septal defect, and right ventricular outflow obstruction--were common in patients with anomalous subaortic innominate veins.
左无名静脉走行异常在解剖标本中鲜有描述。血管造影和超声心动图等检查技术使更多此类异常病例得以发现。本文描述了经解剖学研究确定的另外3例病例。回顾了早期病例以评估相关心脏畸形的类型。临床上，这种异常被认为是良性的。在检查过程中识别出该异常时，应提醒临床医生注意存在相关畸形的可能性。法洛四联症常见的特征——右位主动脉弓、室间隔缺损和右心室流出道梗阻——在主动脉下无名静脉走行异常的患者中也很常见。
