- W2349791156 abstract "Objective:This study investigated the anatomical features of the segmental lumbar artery and vein.The purpose is to improve the safety and the validity of lumbar and sacral spinal surgery.Methods:In our study we dissect the vascular system anterior to lumbar vertebrates of 30 cadavers to learn their characteristics.We choose the indexes to measure as follows (1) The location,numbers and variance of segmental lumbar arteries and veins.Results:The location of the segmental lumbar arteries is firmly related to the location of the vertebrate body.Five cases were found to have the fifth segmental lumbar arteries.9.6% pairs share a common initial stem.Only 65.3% arteries pair with their corresponding vein.There is great variation of the number of the segmental lumbar vein arrange from 1 to 6 mainly 3 on 60 sides of the 30 vena cava.We found that the corresponding relationships of the confluent points of the lumbar veins with the vertebrate body were not so firm as the artery with vertebrate body.And the left and right veins were not regularly paired.38.5% of the left and right veins share a common confluent stem vein and 12.5% of the veins have common confluent stem vein on the same side of the vena cava.Besides anastomoses between the segmental lumbar veins are not rare in these cases.Conclusion:In the operation we should pay special attention to the vein including segmental lumbar veins because of their great variation of their numbers,confluent point,common stem and anastomoses between them." @default.
