AbstractMorel-Lavallee Lesions lead to disruption of lymphatic anatomy that require early identification and may necessitate lymphatic reconstruction. We present the case of a 59-year-old male with lower extremity lymphedema resulting after a severe Morel-Lavallee lesion and treated using lymphovenous anastomoses. He was initially managed with multiple aspirations followed by repeat incision and drainage. At 10 months following his injury, he continued to have swelling of his upper thigh and developed a large festoon medially, with lower leg pitting edema. He was diagnosed with lymphedema via lymphoscintigraphy. His superficial lymphatic anatomy was visualized using indocyanine green (ICG) lymphography and showed diffuse dermal backflow across his thigh, with signs of altered lymphatic anatomy distally. We preformed two lymphovenous anastomoses at the level of his mid-thigh to bypass the lymphatic disruption and restore drainage to his lower leg. After rerouting lymphatic flow from the lower extremity, the patient had overall improvement of his symptoms and reduced swelling with continued therapy. At 5 months postoperatively, his volumetric lower extremity measurements showed a decrease by 314 mL and he began walking again in 20-minute intervals. Lymphedema may be an important consideration following severe Morel-Lavallee lesions. Using modern diagnostic and supermicrosurgical techniques, plastic surgeons can help treat this long-term morbidity.Copyright © 2024. Published by Elsevier Ltd.
