Background: Lymphatic supermicrosurgery is becoming the treatment of choice for refractory lymphedema. Detection and anastomosis of functional lymphatic vessels are important for lymphatic supermicrosurgery.
Methods Navigation lymphatic supermicrosurgery was performed using an operating microscope equipped with an integrated near-infrared illumination system (OPMI Pentero Infrared 800; Carl Zeiss, Oberkochen, Germany). Eight patients with extremity lymphedema who underwent navigation lymphatic supermicrosurgery were evaluated.
Results: A total of 21 lymphaticovenular anastomoses were performed on 8 limbs through 14 skin incisions. Lymphatic vessels were enhanced by intraoperative microscopic indocyanine green (ICG) lymphography in 12 of the 14 skin incisions, which resulted in early dissection of lymphatic vessels. All anastomoses showed good anastomosis patency after completion of anastomoses. Postoperative extremity lymphedema index decreased in all limbs.
Conclusions: Navigation lymphatic supermicrosurgery, in which lymphatic vessels are visualized with intraoperative microscopic ICG lymphography, allows a lymphatic supermicrosurgeon to find and dissect lymphatic vessels earlier and facilitates successful performance of lymphaticovenular anastomosis.
