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.
