Purpose
The purpose of this study is to demonstrate the feasibility of near-infrared fluorescence imaging of subjects with acquired and hereditary lymphedema and lymphovascular disorders and to attempt to correlate imaging phenotype with genotype. Normal and diseased volunteers are evaluated.

1
Persons with Grade I or Grade II lymphedema
|
Drug: near-infrared fluorescence imaging
we conduct near-infrared fluorescence imaging following the off-label use of Indocyanine Green as a lymph contrast agent and the use of a custom designed fluorescence imager to dynamically follow lymphatic trafficking in the arms and legs of subjects. We seek to use the resulting phenotypes acquired in normal and diseased patients to correlate to mutations of specific genes reported to be associated with lymphatic development.

Detailed Description:
Currently, there is no method to assess lymphatic function in subjects with acquired (following surgery or trauma) or hereditary lymphedema. The causes of hereditary lymphedema and the means to distinguish between acquired lymphedema is not available from existing diagnostics. A method to monitor lymphatic function could assist in the development of new therapies, prediction of subjects with susceptibility to acquire lymphedema, and evaluation of subjects' conditions. In this Phase I trial, we conduct near-infrared fluorescence imaging following the off-label use of Indocyanine Green as a lymph contrast agent and the use of a custom designed fluorescence imager to dynamically follow lymphatic trafficking in the arms and legs of subjects. We seek to use the resulting phenotypes acquired in normal and diseased patients to correlate to mutations of specific genes reported to be associated with lymphatic development.
