Use of thermotherapy in management of lymphedema: clinical observations

Abstract

We report clinical observations in 67 patients with chronic lymphedema undergoing hyperthermia. Our technique of hyperthermia is an alternative to microwave therapy, particularly where lymphangitis coexists in the same limb. Preoperative diagnostic evaluation including lymphatic and venous isotopic scintigraphy, Doppler venous flow metrics, and pressure manometry play an essential role in delineating the status of both the lymphatic and venous systems and in determining if hyperthermia is indicated. Our method of treatment consists of producing hot and humid ambience inside the chamber where the limb is situated. The data demonstrate the feasibility of our method of hyperthermia in 67 patients with postlymphangitis lymphedema (either arm or leg). Using this technique, improvement was seen in both limb function and edema.
