The hypothesis for the difference in volume loss within the first week is that, in primary lymphedema, the edema usually begins at the feet with the progression to fibrosis being greater in the distal region.
In primary lymphedema, the proximal region of the thigh is normalized faster than the distal edema with the last region to be normalized being the feet, more specifically the toes.
In secondary lymphedema, the reduction of the edema at the thigh is slower than with primary lymphedema, while the decrease is faster below the knee.
Volumetric reductions below the knee are faster with intensive treatment in secondary rather than in primary lymphedema.
