lymphodema

I was recently diagnosed with cancer of the vulva.  It had affected only one of my lymph groin nodes, but all were removed.  I ultimately developed lymphodema.  I have been having a difficult time finding proper compression stockings, and on a recent long flight, where my therapist told me to wear thigh high stockings, the lymph fluid accumulated in my groin area.  I recently read about a lymph node replacement surgery being done, but seemed to concentrate on breast cancer patients.  Does anyone know more about this?
