摘　　要：目的:为小肠疾病的临床介入诊断及治疗提供血管解剖基础.方法:对8例正常成人小肠标本采用ABS血管铸型、硫酸钡墨汁混悬液血管造影及图像分析进行血管研究.结果:空肠段直动脉通常分三支,即两长支、一短支.回肠段直动脉通常分二支.即长、短各一支.空一回肠段呈移行改变.直动脉在进入肠壁之前可见吻合现象.直动脉的长度、内径及密度(支cm)均存在解剖部位差异性(P<0.05).方法之间无差异性.结论:小肠血管分布有其规律性.血管造影对小肠疾病的诊断有一定价值.To provide normal vascular anatomy for interventional diagnosis and therapy. Materials and Methods: Eight biopsy specimens from normal adults were studied with vascular cast, an-giography and quantitative analysis. Results: The vasa re'cta of the jejunum was composed of two long and one short branches, and the vasa recta of the ileum one long and one short branches. There appeared anastomosis before the vasa recta entered the intestinal wall. There were anatomic differences in length, internal diameter and density of the vasa recta (P<0. 05). Conclusion: There is some regularity in the vascular distribution of the normal intestine, and the angiography is of some value for the diagnosis of intestinal diseases.
