Lymphaticovenous anastomosis (LVA), which involves connecting lymphatic vessels to veins under a microscope, is widely performed around the world as a surgical treatment for lymphedema due to its relatively low patient burden and consistent efficacy. One of the crucial points of LVA is identifying suitable lymphatic vessels from among many lymphatic vessels and connecting them at the most effective site, but in practice, this is not easy to do. To overcome this issue, we have been able to effectively drain lymph by connecting lymphatic vessels to veins just before the occluded site using a lymphatic wire that was just recently developed in Japan. The device guides the subcutaneous deep collecting lymphatic vessels from the peripheral relatively superficial lymphatic vessels. While this special wire is typically adapted in the lower limbs, we have confirmed its effectiveness in upper limb lymphedema as well. Overall, this approach shows promise for improving the accuracy and success rates of LVA procedures, which can have significant benefits for patients with upper limb lymphedema. In this article, we share our experience using lymphatic wire for upper limb lymphedema cases.
