Anatomy of the superficial lymphatics of the abdominal wall and the upper thigh and its implications in lymphatic microsurgery

Abstract

Background The recent advent in the surgical treatment of lymphedema necessitates a more detailed understanding of the anatomy of the lymphatic system. Lymphovenous anastomosis (LVA) requires a precise knowledge of the anatomy of the superficial lymphatic collectors in relation to the superficial veins. In vascularized lymph node transfer (VLNT), donor site lymphatic function must be preserved. Methods Using the previously described technique, the superficial lymphatic drainage of 8 anterior hemi-abdomen/upper thigh specimens from 4 fresh human cadavers was investigated. Results The upper and lower abdominal collectors were found above Scarpa's fascia immediately below the subdermal venules...
