Late results of lymphovenous anastomoses in lymphedema of the lower extremities

: The authors examined 152 patients with lymphedema of the lower limbs 2-6 years after operation for lymphovenous anastomoses (LVA). They evaluated the dynamics of edema according to Alberton's formula, the changes in the character of the episodes of erysipelas, and the patient's feeling of heaviness in the involved limb. The function of the anastomosis was studied by the radioisotope method. Positive results were recorded in 99 patients. In the remaining patients the LVA did not function and the symptoms of lymphedema did not change or progressed. The effect of LVA was found to be positive in 51 patients in the group of 69 patients with secondary form of lymphedema and in 48 of 83 patients with the primary form of the disease. The last-mentioned was connected with congenital insufficiency of lymph drainage. The condition of the collecting lymphatics is an important factor of LVA efficacy: the effect of LVA was positive in 68 patients in hyperplasia and in 31 patients in hypoplasia of the lymphatics. The results of LVA are improved by regular nonoperative management for the correction of endocrine-immunological and hemostatic factors as well as by stimulation of lymph drainage in the limb and prevention of inflammatory complications.
