Comparison of the rate of concomitant proximal venous stenosis between the upper and lower extremities in patients with secondary lymphedema undergoing lymphaticovenous anastomosis

Concomitant iatrogenic proximal venous stenosis increases venous pressure and can be a risk factor for unfavorable outcomes of lymphaticovenular anastomosis (LVA) in extremities with secondary lymphedema. This study investigated the frequency and relevant factors of venous stenosis in patients diagnosed with secondary lymphedema who underwent LVA.
