Correlation between the results of the first lymphatic venous anastomosis (LVA) and clinical parameters. Rate of improvement (RI) after the first LVA and preoperative lower extremity lymphedema (LEL) index exhibited moderate positive correlations (r = 0.42, p < 0.05) (A). However, RI after the first LVA was not correlated with any stage of normal, ectasis, contraction, and sclerosis type classification (NECST) (B), lymphoscintigraphy (C), or indocyanine green (ICG) lymphography (D).
