The Imaging Research for Thoracolumbar Spine Lateral Vascular Anatomy

Object: To provide the anatomic basis of imaging for the segmental vessels of the thoracolumbar spine side and measure the distance between two adjacent segmental arteries in the three-dimensional images. Method: After conducting angiography for 50 cases of normal adults through the ulnar vein, carrying out thoracolumbar CT scans. In the image observation: The course and adjacent relationship of the segmental vessels; Measuring range: the distance between the upper and lower segmental arteries of the middle line of spine side. Results: We could observe the course and the adjacent relationship of thoracolumbar spine lateral vascular. In between the upper and lower segmental vessels consists a relatively non-vascular nerve safe zone where the intervertebral space locates. And we surveyed the related datas. Conclusion: Three-dimensional reconstruction of CT images can effectively observe the course and adjacent relationship of the thoracolumbar spinal lateral segmental artery, and can accurately measure the safe zone.
