Lymphedema is a disorder in which a congenital or acquired dysfunction of lymphatic transport results in an excessive accumulation of protein-rich fluid in the interstitial tissue
Advances in microsurgical techniques and understanding of the lymphatic system have led to new clinical advances in the surgical treatment of secondary lymphedema, including lymphovenous anastomosis (LVA), also known as lymphatic venous shunt , establish an anastomosis between a submillimeter diameter lymphatic vessel and an adjacent vein of similar size
In earlier studies, assessment of contrast-enhanced US (CEUS) to identify sentinel lymph nodes simultaneously visualized lymphatic vessels
In this single-center retrospective study, CEUS was performed on all enrolled patients before upper extremity LVA surgery between October 2019 and September 2021
All 11 patients were female (mean age 56 ± 8 [SD])
This study demonstrates that contrast-enhanced US (CEUS) examination with intradermal injection of microbubbles is an important imaging tool for identifying additional targets for lymphatic anastomosis when indocyanine green (ICG) fluorescence lymphography cannot clearly visualize the lesion
