Our supramicrosurgical experience of lymphaticovenular anastomosis in lymphoedema patients to prevent cellulitis

OBJECTIVE: Aim of this paper is to present our reduction of the frequency of cellulitis before and after supramicrosurgical lymphaticovenular anastomosis (s-LVA) in lymphoedema patients, and discuss the possibility to perform this technique outside Japan. PATIENTS AND METHODS: 37 patients affected by lymphoedema were enrolled. All patients received preoperative indocyanine green lymphography. Under local anaesthesia s-LVA was performed on all patients. All patients were followed for 1 year. Lymphoedema was staged using the lymphoedema staging classification recommended by the International Society of Lymphology. Cellulitis rate was recorded for all patients the year before and after the s-LVA. A t-test was used to evaluate differences in the frequency of cellulitis the year before surgery and the year following surgery. RESULTS: Cellulitis incidence decreased in all patients, with a mean 1.7 cases the year before s-LVA and 0.1 the year after s-LVA. A significant difference between preoperative and postoperative cellulitis rate was found (p = 0.0012). CONCLUSIONS: This study reports our s-LVA case series of lymphoedema patients. With the proper learning curve, s-LVA may be reproduced and lymphoedema patients may gain a better quality of life and a reduced cellulitis rate.
