Duplicated inferior vena cava (IVC) is a rare anatomical anomaly as a result of failed regression of the left supracardinal vein during the embryonic stage. This anatomical variation has certain surgical implications and could lead to potential catastrophe perioperatively. We hereby report a case of a 54 years old male in whom a whipple procedure was performed with type 1 duplicated IVC for ampullary adenocarcinoma. Review of current literature of such anatomical anomaly will also be discussed. This venous anomaly must be kept in mind in all surgical procedures involving the retroperitoneum to minimise the risk of incomplete lymph node dissection and life-threatening bleeding, and to guide management for deep vein thrombosis in the post-operative setting.
重复下腔静脉（IVC）是一种罕见的解剖学异常，是胚胎期左上心静脉退化失败的结果。这种解剖变异具有一定的手术意义，可能导致围手术期的潜在灾难。我们在此报告一例54岁男性，因壶腹腺癌接受了Whipple手术，其下腔静脉为1型重复。本文还将讨论有关这种解剖异常的当前文献综述。在所有涉及腹膜后的外科手术中，都必须牢记这种静脉异常，以尽量减少淋巴结清扫不彻底和危及生命的出血风险，并指导术后深静脉血栓形成的管理。
