RESUMO
In this report, we discuss the postoperative protocol for patients undergoing lymphaticovenous anastomosis (LVA) in our unit. Immediately after LVA, the incision site is closed over a small Penrose drain and a simple gauze dressing is applied without compression. In the first 5 days, ambulation is allowed, but limb elevation is actively encouraged to promote lymphatic flow across the newly formed anastomosis. Prophylactic antibiotics are routinely given to prevent infection because this patient group is susceptible to infections, which could trigger thrombosis in the anastomosis.

RESUMO
BACKGROUND: The depth of graft harvest and the residual dermis available for reepithelization primarily influence the healing of split-skin graft donor sites. When the thigh region is chosen, the authors hypothesize based on thickness measurements that the anterolateral region is the optimal donor site. METHODS: Full-thickness skin specimens were sampled from the anteromedial, anterior, and anterolateral regions of human cadavers. Skin specimens were cut perpendicularly with a custom-made precision apparatus to avoid the overestimation of thickness measurements. The combined epidermal and dermal thicknesses (overall skin thickness) were measured using a digital calliper. The specimens were histologically stained to visualize their basement membrane, and microscopy images were captured. Since the epidermal thickness varies across the specimen, a stereological method was used to eliminate observer bias. RESULTS: Epidermal thickness represented 2.5% to 9.9% of the overall skin thickness. There was a significant difference in epidermal thickness from one region to another (P<0.05). The anterolateral thigh region had the most consistent and highest mean epidermal thickness (60+/-3.2 microm). We observed that overall skin thickness increased laterally from the anteromedial region to the anterior and anterolateral regions of the thigh. The overall skin thickness measured 1,032+/-435 microm in the anteromedial region compared to 1,220+/-257 microm in the anterolateral region. CONCLUSIONS: Based on skin thickness measurements, the anterolateral thigh had the thickest epidermal and dermal layers. We suggest that the anterolateral thigh region is the optimal donor site for split-skin graft harvests from the thigh.
