Development imaging and experimental model for study pathogenesis and treatment efficacy of postmastectomy lymphedema

The experimental model was created during an abdominal dissection of the rat mesentery and ligation of the collecting vein of mesentery. It was found that mesentery edema was developed for 20-30 min. Simultaneously monitoring of main the parameters of blood and lymph flow revealed significant increasing of interstitial water amount (up to 3 times), reduction of blood microcirculation, increasing of blood vessels permeability, decreasing of lymph microvessels diameter, phasics contractions, and lymph flow velocity.
