小肠的血供在维系重要生理功能方面起决定作用.小肠血管改变与许多小肠疾病有关,在临床医学和影像学迅速发展的今天,在小肠疾病(尤其是小肠肿瘤)的诊断和介入治疗上,对小肠血管的研究和认识更具有重要的理论意义和临床价值.1 小肠血管研究的历史回顾早在一个世纪前,许多学者采用了墨汁血浆或卡红明胶灌注,厚片或连续切片显微观察;硅胶灌注厚切片透明观察;微血管造影X线摄片;微血管铸型扫描电镜观察等方法,对正常条件下狗、兔、鼠、猪、猴及马等动物小肠绒毛血管丛进行研究,并提出四种构型观点,即:阶梯型(绒毛动脉和静脉同时从绒毛底部向顶部延伸,在行经中彼此之间形成似“阶梯状”的毛细
The blood supply of the small intestine plays a decisive role in maintaining important physiological functions.Changes in the small intestine and many small intestinal diseases, in the rapid development of clinical medicine and imaging today, in the diagnosis and interventional treatment of small bowel diseases (especially small bowel tumors) The study and understanding of the intestinal vessels have more important theoretical and clinical values.1 Historical Review of Small Bowel Vascular Research A few centuries ago, many scholars used ink plasma or card red gelatin infusion, thick slices or serial sections microscopic observation ; Silicone perfusion thick section of transparent observation; angiography X-ray; micro-tube casting scanning electron microscopy observation methods such as dogs, rabbits, mice, pigs, monkeys and horses and other animals under the intestinal villus vascular clumsy and proposed Four configurational perspectives, namely: Ladder (villus arteries and veins extending from the bottom to the top of the villi at the same time, forming “ladder-like” capillaries
