High-frequency ultrasound combined with shear wave elastography to evaluate the efficacy of lymphaticovenular anastomosis in patients with secondary lymphedema

The reduction in SEFS in the affected limb after LVA, along with the decreased SWV in the dermis and increased SWV in the subcutaneous tissue layer, suggests that LVA effectively reduces lymphatic fluid retention across all tissue layers. This provides novel ultrasonographic evidence for assessing and refining treatment efficacy and follow-up.
