Abstract：Objective To observe the imaging of lumbar arteries with computed tomographic ( CT ) angiography and to explore the clinical signiifcance.Methods From March 2012 to June 2012,55 patients accepted abdomen CT angiography,and both aorta abdominalis and arteriae lumbales were clearly displayed.The starting location and deifciency of lumbar arteries,the angle formed between the starting location of lumbar arteries and the aorta abdominalis and the inner diameter were observed.The distance of adjacent lumbar arteries from the starting location of lumbar arteries were measured.The same starting point shared by adjacent lumbar arteries were detected.Results Most of the lumbar arteries originated from the vertebral body plane of the corresponding aorta abdominalis.A lack of lumbar arteries was found in 9 cases ( 16.4％).The inner diameter was gradually increased from top to bottom,and no statistically signiifcant differences were observed between the left and right side (P＜0.05 ).An acute angle was formed between the 1st,2nd and 3rd lumbar arteries and the aorta abdominalis respectively,and an obtuse angle was formed between the 4th lumbar artery and the aorta abdominalis.The distance of adjacent lumbar arteries from top to bottom was gradually reduced.The same starting point shared by adjacent lumbar arteries was noticed in 3 cases ( 5.5％).Conclusions Obvious local anatomical variations can be observed in lumbar arteries.Before the interventional treatment,the local anatomical characteristics of lumbar arteries should be mastered,and the blood supply of the spinal cord cannot be affected.
