Three dimensional anatomy of the lymphatic system in a fresh cadaver using multi-detector-row computed tomography

我们阐明了下肢淋巴系统的三维解剖，以及淋巴水肿的淋巴变化。首先，我们研制了一种新的新鲜尸体淋巴系统造影剂。我们将造影剂注射到人体的淋巴系统，并通过计算机断层扫描对淋巴系统进行成像。我们发现在下肢存在五种淋巴流动模式。当外科医生决定淋巴结清扫区域时，这些知识是非常重要的。我们发现一些淋巴收集血管被阻断造影剂飞回淋巴毛细血管。这有助于了解人体淋巴水肿的发生机制。

We elucidated three dimensional anatomy of the lymphatic systemn in lower leg, and lymphatic changes in lymph edema.First, we developed new contrast medium for lymphatic system in fresh cadaver. We injected the contrast medium to lymphatic system in human cadaer and imaged the lymphatic system by computed tomography.We found that five patterns of lymphatic flow are exsted in lower legs. This kwouledge is very important when surgeons decide the lyuphnode dissection area. And we found that some lymph collecting vessels are interrupded and contrast medium flew back to the lymph capillary. This helps understanding to the mechanism of human lymph edema.
