我们对16例髂腰静脉进行了尸体研究，以确定手术解剖。发现了两种变体;一条静脉与下腔静脉的平均距离为3.74 cm（11/16），两条独立的引流静脉与腔静脉的平均距离分别为2.98 cm（近端）和6.24 cm（远端）（5/16）。一致的是，近端静脉在大血管内侧回缩时撕裂。静脉平均长1.6cm，平均宽1.07cm。3个股骨柄短于0.5 cm。髂肌、腰肌和第五腰椎椎体的引流多为两支或多支的分支。闭孔神经在口外侧平均2.76cm处与静脉浅面交叉。在其中4例中，该距离小于1.5 cm。通常情况下，腰骶干交叉深，平均距离为2.5厘米的嘴，但在三个静脉，这个距离为1厘米或less.Our研究结果强调需要适当的解剖髂腰静脉结扎前暴露的前腰椎。
We carried out a cadaver study of 16 iliolumbar veins in order to define the surgical anatomy. Two variants were found; a single vein at a mean distance of 3.74 cm from the inferior vena cava (11 of 16) and two separate draining veins at a mean distance from the vena cava of 2.98 cm for the proximal and 6.24 cm for the distal stem (5 of 16). Consistently, the proximal vein tore on attempted medial retraction of the great vessels. The mean length of the vein was 1.6 cm and its mean width 1.07 cm. Three stems were shorter than 0.5 cm. Two or more tributaries usually drained the iliacus and psoas muscles, and the fifth lumbar vertebral body. The obturator nerve crossed all veins superficially at a mean of 2.76 cm lateral to the mouth. In four of these, this distance was less than 1.5 cm. Usually, the lumbosacral trunk crossed deep, at a mean distance of 2.5 cm lateral to the mouth, but in three veins, this distance was I cm or less.Our findings emphasise the need for proper dissection of the iliolumbar vein before ligature during exposure of the anterior lumbar spine.
