Impact of Magnetic Resonance Lymphography on Lymphaticolvenular Anastomosis for Lower-Limb Lymphedema.

Background:  Although several investigations have described the safety, utility, and precision of magnetic resonance lymphography (MRL) as a preoperative examination for lymphaticovenular anastomosis (LVA), it is unclear how much MRL assistance impacts LVA results. The present study aimed to clarify the outcome of MRL-assisted LVA for leg lymphedema using body water measurements obtained by bioelectrical impedance analysis.

Methods:  The water reductive effect of MRL-assisted LVA in female secondary leg lymphedema patients was compared with that of non-MRL-assisted controls in this retrospective study.

Magnetic resonance lymphography as three-dimensional navigation for lymphaticovenular anastomosis in patients with leg lymphedema.

Background: Precise mapping of functional lymphatic vessels is essential for successful lymphaticovenular anastomosis (LVA). This study aimed to clarify the precision of magnetic resonance lymphography (MRL) in detecting lymphatic vessels prior to LVA.

Methods: Eighteen patients with leg lymphedema were recruited for this prospective study.

Extracellular Water Ratio as an Indicator of the Development and Severity of Leg Lymphedema Using Bioelectrical Impedance Analysis.

This case-control retrospective study focused on the extracellular water ratio (%ECW) of lymphedemic limbs measured by bioelectrical impedance analysis (BIA) as a possible indicator of the development and severity of unilateral and bilateral leg lymphedema. BIA was used to evaluate changes in %ECW due to lymphedema in female patients with unilateral secondary leg lymphedema and in healthy controls. Receiver operating characteristic (ROC) analysis was employed to assess the diagnostic ability of %ECW to distinguish leg lymphedema patients from controls.

Water Reductive Effect of Lymphaticovenular Anastomosis on Upper-Limb Lymphedema: Bioelectrical Impedance Analysis and Comparison with Lower-Limb Lymphedema.

Background:  We previously examined the water reductive effect of lymphaticovenular anastomosis (LVA) using bioelectrical impedance analysis (BIA) measurement on lower-limb lymphedema and revealed mean water volume reduction and edema reduction rate by leg LVA to be 0.86 L and 45.1%, respectively.
