下腔静脉(inferior vena cava,IVC)存在一些较为少见的解剖变异,如高位分叉、双支、缺如、左位下腔静脉等,且常常合并其他脏器静脉属支变异。据文献报道,左位下腔静脉发生率仅为0.1%左右,一般无明显临床表现[1]。下腔静脉虽深埋腹腔内,但临床上可采用深静脉置管、介入手术等方法进行治疗。临床工作者应对下腔静脉的解剖变异有一定的了解,以提高诊疗准确度,避免误诊或意外损伤。以往的文献中,左位下腔静脉多为尸体解 In the inferior vena cava (IVC), there are some rare anatomical variations, such as high bifurcation, double branch, absent, left inferior vena cava and so on, often associated with varicose veins in other organs. According to the literature, the incidence of left vena cava venous only about 0.1%, generally no significant clinical manifestations [1]. Although the deep IVC deep intraperitoneal, but the clinical use of deep vein catheterization, interventional methods such as treatment. Clinicians should have some understanding of anatomical variation of IVC in order to improve the accuracy of diagnosis and treatment and avoid misdiagnosis or accidental injury. In the past literature, the left inferior vena cava mostly for the body solution
