Indocyanine green (ICG) lymphography is useful for localization of superficial lymphatic vessels where dermal backflow is not observed, but not for lymphatic vessels in deep layer or where dermal backflow is observed. Ultrasound has been applied in LVA and is considered useful for localization of lymphatic vessels with ICG lymphography cannot be visualized.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Fifty\u2010five secondary lower extremity lymphedema (LEL) patients who underwent LVA were classified into two groups, ultrasound\u2010detection\u2010of\u2010lymphatic group (US group, <jats:italic>n<\/jats:italic>\u2009=\u200929) and non\u2010ultrasound\u2010detection\u2010of\u2010lymphatic group (non\u2010US group, <jats:italic>n<\/jats:italic>\u2009=\u200926), and assessed.
