本研究的目的是观察5个月人胎儿的气管血管构筑，并确定它是否有别于其他作者所描述的成人气管的血管构筑。用腐蚀铸型技术显示管床，并用扫描电子显微镜观察。较大的血管：纵向的气管-食管动、静脉及其在软骨间的环行的节段性分支的排列与成人的气管相似。然而，在人的气管粘膜下静脉丛中没有发现血窦的报道，推测作为电容系统的血窦的可能功能与功能性呼吸道有关，因此，这种血管特化在胎儿中尚未发育。
The aim of this study was to examine the tracheal vasculature in 5 month human foetuses, and to determine whether it differs from that previously described by other authors for adult human trachea.The vascular bed was visualized using the technique of corrosion casting and examined by scanning electron microscopy.The arrangement of larger vessels: longitudinal tracheo-oesophageal arteries and veins, as well as their segmental branches running circumferentially in the inter- cartilaginous spaces, was similar to that observed in the trachea of adults. However, no blood sinuses reported to occur in the submucous venular plexus of the human trachea could be found in the foetuses.It is postulated that the possible functions of such sinuses acting as the capacitance system are related to the functional respiratory tract; hence, this vascular specialization is not yet developed in the foetus.
