7、腸動脈、回腸動脈，右結腸動脈，中結腸動脈。解剖上,這些主要分支又反復發(fā)出分支，通過多級動脈弓相吻合，由最后分級動脈弓發(fā)出的直小動脈進入腸壁。這些腸系膜上動脈主要分支均通過動脈弓彼此相鄰吻合。彩色多普勒超聲（CDFI）是在二維超聲基礎上疊加多普勒彩色編碼技術，二維超聲可以取得清晰的血管二維多切面圖像，彩色多普勒不但可以顯示血管內(nèi)的彩色多普勒信號，而且能夠測量血管內(nèi)部的血流頻譜信號，觀察其頻譜形態(tài)，測量其多種血流動力學參數(shù)，因此，CDFI已經(jīng)廣泛應用到心血管、腹部大血管、四肢血管當中成為評價血管的優(yōu)選檢查手段。目前，CDFI在SMA的應用當中主要以研究其主干為主，
