This study was designed to compare the party balloon assisted Valsalva with the conventional Valsava for exhibiting the reverse venous flow in superficial venous valvular incompetence duplex examination.
In this study, we compared the Party Balloon assisted Valsalva with Conventional Valsalva maneuver in diagnosis of superficial venous valvular reflux of lower limb by crossover study.
