Title: Applied anatomy study of the arteries of lower lumbar vertebrae.
Abstract: [Objective]To study the anatomical characteristic of lower lateral lumbar artery and to provide academic basis to reduce arterial bleeding in the lower lumbar lateral surgical approach. [Methods]Anatomical observation arteries of lower lumber vertebrae was carried out in 21 dissected adult corpses from their origin to the processus transversus-the routes,branches,exterior diameter of these arteries and their relationship with the intervertebral foramen and prezone of processus transversus was analyzed.[Results]Different LAs appearred in different rates here.The appearance rates of L3A and L4A remained constant while that of L5A was quite variable.The main trunks and branches of L3A and L4A were distributed at the rate of 71.43% in the lateral border of the pedicle of vertebral arch of L3A and 62.07% in the 1/3 of intervertebral foramen of L4、5A.In the prezone of processus transversus,the anterior branches of L3A and L4A originated mostly from the inner side of point upper 1/3,then slanted outward down to the outer side of middle point 1/3 at the rate of 60% or from the upper 1/3 point down to the lower 1/3 point at the rate of 58.33%.[Conclusion]A good treatment of the arteries near the lumbar vertebrae,intervertebral foramen and those in the prezone of processus transversus is an effective way to reduce bleeding in a certain operation.
