Abstract:
Objective To investigate the normal reference values of abdominal aorta and its branches in Southwest China, so as to provide basis for clinical diagnosis and treatment of abdominal aortic aneurysm. Methods The length, diameter and angle of the abdominal aorta and its branches were measured in 20 cadavers. At the same time, 300 cases without obvious pathological changes in four urban populations were selected for abdominal CT angiography (CTA) to measure the length, diameter and angle of abdominal aorta and its branches. Results Display rate of abdominal aorta was 100%,the average length of abdominal aorta was (12.96±0.81) cm, the diameter of abdominal aorta was (1.93±0.28) cm, (1.55±0.23) cm, (1.61±0.19) cm in renal artery plane (Ⅰ), inferior mesenteric artery plane (Ⅱ) and lower edge plane of lumbar vertebrae (Ⅲ), and the average value on image was (2.17 ± 0.42) cm, (1.81 ± 0.40) cm, (1.99 ± 0.53) cm; Display rate of common iliac artery was 100%, the angle between left and right common iliac artery was (59.80± 4.66) ° and the diameter of the end was (1.16±0.33) cm and (1.12±0.11) cm; Display rate of celiac trunk on cadaver was 100%, the average length was (1.61±0.27) cm, the average diameter on cadaver was (0.78±0.71) cm, the image was (0.88± 0.31) cm; Display rate of renal artery was 100%, the average length of the left renal artery was (2.58 ± 0.50) cm, that of the right was (4.26±0.65) cm, the initial average diameter of the left renal artery was (0.55±0.24) cm, and the right renal artery was (0.62±0.20) cm; Display rate of the superior mesenteric artery was (100%), that of the on cadaver was (4.56 ± 0.29) cm, that of the image was (4.93 ± 0.84) cm, and that of the angle between the abdominal aorta was (38.05±5.99)°; Display rate of the inferior mesenteric artery was (100%),the average length of the inferior mesenteric artery was (6.57±0.79) cm on the cadaver, the image was (6.70±0.76) cm, and that of the angle between the abdominal aorta was (73.79 ± 9.62) ° and the initial diameter was (0.48 ± 0.29) cm. Conclusion The normal reference values of abdominal aorta and its visceral branches in Southwest China population were measured. CTA has a special advantage in showing the lesions of abdominal aorta and its branches in lumen, extraluminal and vascular wall, which can provide anatomical data of patients before operation.
