| Research Abstract |
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.
