The peculiarities of the structure, skeletotopy, and syntopy of the lumbar lymphatic collector were studied on 20 5-8 week-old embryos and on 80 9-36 week-old fetuses using a complex macro-microscopic method. It is found that the lumbar lymphatic collector in fetuses at 9-10 weeks was represented by retroperitoneal and retroaortic lymphatic sacs that had a fusion mode of formation and were interconnected. Retroperitoneal sac was located in the projection of L(I)-L(IV) and was in contact with the anterior surface of the abdominal aorta and inferior vena cava, aortic lumbar paraganglia, abdominal aortic plexus and ganglia of sympathetic trunk. Retroaortic sack at L(I)-L(II) was adjacent to posterior surface of the aorta, the lumbar vertebrae and the medial crus of the diaphragm. These topical relations were preserved throughout the whole fetal period. However, in fetuses of 11-13 weeks lymphatic sacs formed the lymphatic plexuses, while in fetuses of 14-36 weeks they formed lumbar lymph nodes and their interconnecting vessels.
采用宏观-微观综合方法，对20例5-8周龄胚胎及80例9-36周龄胎儿的腰淋巴收集器的结构、骨骼定位及毗邻关系特点进行了研究。结果发现，9-10周龄胎儿的腰淋巴收集器由腹膜后和主动脉后淋巴囊组成，它们以融合的方式形成并相互连接。腹膜后囊位于L(I)-L(IV)的投影处，与腹主动脉、下腔静脉的前表面、主动脉腰旁神经节、腹主动脉丛及交感干神经节相接触。L(I)-L(II)处的主动脉后囊毗邻主动脉后表面、腰椎及膈内侧脚。这些局部关系在整个胎儿期均得以保留。然而，在11-13周龄的胎儿中，淋巴囊形成淋巴丛，而在14-36周龄的胎儿中，它们形成腰淋巴结及其相互连接的血管。
