Anomalies of the inferior vena cava result from failures of regression during embryogenesis. Although occurring relatively infrequently, they can pose serious hazards to the surgeon during aortic aneurysm repair. Based on 2 recent cases, embryologic origins, incidence and clinical presentation of these anomalies are discussed. Different suggestions are proposed that might aid the surgeon in dealing with these anomalous structures during operations on the abdominal aorta.
下腔静脉异常是胚胎发育过程中退化失败所致。虽然其发生相对罕见，但在主动脉瘤修复手术中可能给外科医生带来严重风险。基于最近的2例病例，本文讨论了这些异常的胚胎学起源、发生率及临床表现。提出了不同的建议，可能有助于外科医生在腹主动脉手术中处理这些异常结构。
