| 【Abstract】 Objective：To investigate the regional anatomy of the distal abdominal aorta and provide the rational for distal abdominal aorta blockage.Method：27 specimen of human being were used and the main branches of the distal abdominal aorta locally were dissected. The distance between branches and the distance between branches and peripheral important organs were investigated and analyzed statistically.Result：The distance between the inferior mesenteric artery and the distal point of the abdominal aorta bifurcation and between the inferior mesenteric artery and the third lumbar artery was 2.73－5.57cm（average，4.27±0.8cm） and 0.69-1.33cm（average，0.46±0.52cm） respectively.The distance between the third and fourth lumbar arteries and between the fourth lumbar artery and medial sacral artery was 1.27-3.45cm（average，2.18±0.48cm） and 0-2.42cm（average，1.09±0.62cm） respectively.The distance between the medial sacral artery and the distal point of the bifurcation of the abdominal aorta was 0.02-1.50cm（average，0.53±0.37cm）.The distance between the third and the fourth lumbar arteries and that between the fourth lumbar artery and the median sacral artery was significantly different（P＜0.01）.The midpoint of their interval was 2.71±0.62cm away from abdominal aorta bifurcation.Conclusion：The abdominal aorta between the third and fourth transverse lumbar arteries is the widest and midpoint of their interval to abdominal aorta bifurcation is optimal，which is suitable for distal abdominal aorta blockage. |
