The Lower Thoracic Spine (t5-t11) Vertebral Side Observation And Clinical Significance Of Blood Vessels And Nerves

Objective:Lower clinical spine (thoracic 5-11 chest vertebrae) extreme lateral interbody fusion (XLIF) provide anatomical basis.Method:Dissected 12 adult cadavers (six males), observing chest 5 - 11 thoracic vertebra and the adjacent lateral neurovascular structures course, distribution and the adjacent relations, extreme lateral interbody fusion type (XLIF) in the middle and lower To provide anatomical data thoracic.Results:(1) chest 5 - Chest 11 segmental vessels are more constant in the last segment of vein, segmental artery in the next, take the Central line and the corresponding lower-level vertebral body. Sympathetic trunk on both sides of the chest 6 - 9 issued thoracic splanchnic nerve, thoracic 10 - 12 issue of thoracic viscera of small nerves. Azygos vein in the spinal column on the right, down slightly favor the process of moving the left spine, thoracic aorta Traveling in the spine on the left edge of the process of moving down to the right side, the right sympathetic trunk and the left azygos vein is much larger than the distance between the sympathetic the distance between dry and thoracic aorta.(2) chest 5 - 11 segmental thoracic vein and the end plate 11 on both sides of the distance to chest (7.93±1.53mm) maximum, the segmental artery and the inferior endplate of the distance to the left chest of 10 (3.88±0.66 mm), right (3.83±0.53mm) maximum, thoracic aorta and the left sympathetic trunk of the distance to chest 7 (14.24±2.33mm) maximum, azygos vein and the right of the sympathetic trunk of the distance to chest 10 (32.16±3.64 mm) maximum.(3) surgery because the left sympathetic trunk security zone under the direction forward line in the left chest 8 (12.88±1.63,12.57±2.46mm) maximum, the right to thoracic 10 (32.16±3.64,14.88±1.72mm) maximum . Conclusion:(1) lateral margin of thoracic neurovascular complex line of extreme lateral interbody fusion (XLIF) higher risk(2) on the right than the left side of a large security zone operation.(3) in the VATS help contribute to the extreme lateral interbody fusion (XLIF) surgical procedures carried out smoothly.
