수술 중 발견된 중복 하대정맥

Abstract

Duplicated inferior vena cava (IVC) is a congenital anomaly seen rarely in the general population. Patients with IVC variants usually do not present any symptoms and are found incidentally in many cases. However, physicians are urged to recognize the presence of such anomalies during diagnostic or invasive procedures as these variants of blood vessel systems can impose substantial implications in certain clinical situations. Subsequently, information about IVC variants may become critical if surgical injuries or predisposing conditions act as life-threatening risks to patients during medical procedures. We present a case of duplicated IVC in a 68˗year˗old female patient with rectal cancer where an IVC anomaly was found during surgical resection of her tumor. From our experience, we emphasize the importance of having the knowledge of IVC variations in patients undergoing invasive surgical procedures which may involve large vessels.
