解剖1例中年男尸,约50岁,身长170 cm,外形无畸形,发现其腹主动脉及下腔静脉易位,表现为左位下腔静脉合并奇静脉变异(图1)。解剖学研究表明,下腔静脉变异类型多样,其中左位下腔静脉变异发生率为0.2%~0.5%。为积累解剖学资料,报道如下:该例左位下腔静脉于L4~5椎间盘前、 Anatomy of a middle-aged male body, about 50 years old, 170 cm in length, without deformity and found that the abdominal aorta and inferior vena cava translocation, showed left vena cava inferior vena cava with aortic variability (Figure 1). Anatomical studies have shown that the types of IVC variability, including left vena cava variability of the incidence of 0.2% to 0.5%. To accumulate anatomical data, reported as follows: This case left inferior vena cava in L4 ~ 5 anterior intervertebral disc,
