In 67 human fetuses of the crown-rump length from 58 mm to 285 mm (10 to 28 weeks of fetal age) the variability of the arterial vascularization of the terminal ileum was studied using the injection method. Three main angiomorphological types were distinguished on the basis of the frequency of occurrence of the ileocolic artery and the superior mesenteric artery ramifications and their contribution to vascularization of this part of the alimentary canal. Most frequent was found type I [46.3%] in which arterial supply of the terminal ileum stemmed from the recurrent ileal artery only or from the recurrent ileal artery and the superior recurrent artery. The type II [43.3%] was observed less frequently. In this type the terminal ileum was supplied by the recurrent ileal artery and the ileal branch of the ileocolic artery. In the most seldom type III [10.4%] the terminal ileum was vascularized by the stem of the superior mesenteric artery. The results were compared with those reported by other authors who studied the similar problem in adults.
在67例头臀长为58毫米至285毫米（胎龄10至28周）的人类胎儿中，采用注射法研究了回肠末端动脉血管形成的变异性。根据回结肠动脉和肠系膜上动脉分支的出现频率及其对消化道这一部分血管形成的贡献，区分出三种主要的血管形态学类型。最常见的是I型[46.3%]，其中回肠末端的动脉供应仅来自回肠返动脉或来自回肠返动脉和上回肠动脉。II型[43.3%]出现频率较低。在这种类型中，回肠末端由回肠返动脉和回结肠动脉的回肠支供应。在最罕见的III型[10.4%]中，回肠末端由肠系膜上动脉主干供血。将结果与其他研究成人类似问题的作者报告的结果进行了比较。
