Abstract
We would like to thank the respondent for their interest in our recent study regarding using bioelectrical impedance analysis (BIA) in patients with breast cancer-related lymphedema treated by lymphaticovenular anastomosis (LVA).1Roh S. Koshima I. Mese T. Imai H. Aoki G. Kawano R. et al.Bioelectrical impedance analysis in patients with breast cancer-related lymphedema before and after lymphaticovenular anastomosis.J Vasc Surg Venous Lymphat Disord. 2023; 11: 404-410Abstract Full Text Full Text PDF Scopus (0) Google Scholar In our study, we investigated the role of BIA in assessing the outcomes of LVA in patients with breast cancer-related lymphedema. In brief, we found that segmental multifrequency BIA and circumferential volume measurement were strongly correlated in lymphedema-affected upper limbs, both before and after LVA. As the respondent indicated, our findings highlight the correlations between inter-limb ratios for volume, extracellular water, and extracellular/total body water. In addition, we found a negative correlation between the phase angle and segmental multifrequency BIA and circumferential volume. We agree that the respondent's findings are novel and highlight the clinical value of BIA measurement for examining water volume reduction after LVA in patients with arm or leg lymphedema.2Yasunaga Y.

Taken together, we believe that an important future direction would be a largescale standardized study investigating the efficacy of BIA measurement in patients with lymphedema with a focus on early detection, diagnosis, and treatment. We would like to thank the respondent for their insightful and constructive comments on our study. Evaluation of the effect of lymphaticovenular anastomosis using bioelectrical impedance analysisJournal of Vascular Surgery: Venous and Lymphatic DisordersVol. 11Issue 4PreviewI read the article entitled “Bioelectrical impedance analysis in patients with breast cancer-related lymphedema before and after lymphaticovenular anastomosis,” reported by Roh et al1 with great interest. This cross-sectional, single-center retrospective study evaluating the effect of lymphaticovenular anastomosis (LVA) using bioelectrical impedance analysis (BIA) found strong correlations between the BIA parameters and conventional circumferential volume measurement both before and after LVA in patients with upper limb lymphedema.
