Abstract
Abstract 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.
Highlights
Thoracolumbar spine section refers to the T11-L2 section, which is an important structural transition zone at the junction of thoracolumbar
This study focuses on the research of the arrangement, distribution and the adjacent relationship of the thoracolumbar spinal lateral vascular by image technology
Observing the three-dimensional images provides the information about the arrangement and distribution of segmental vessels
Summary
Thoracolumbar spine section refers to the T11-L2 section, which is an important structural transition zone at the junction of thoracolumbar. This section has a deeper anterior approach position, complex anatomical structure, and high risk for larger trauma and complications during traditional surgeries. Since Mack applied video-assisted thoracoscopic surgery (VATS) to treat thoracic disc herniation for the first time in 1993, it has been widely used in the treatment of various thoracic and lumbar spine diseases. Compared with the conventional open surgery, it has following advantages: less traumas, less bleeding and faster recovery, less interference to the old and weak patients, or those with poor heart and lung function, extending the surgical indications. Few applications- oriented anatomical studies have been done on thoracolumbar lateral vascular, especially those combined with image technology
