Compression stocking prevents increased venous retrograde flow time in the lower limbs of pregnant women

Objectives To analyze the effect of graduated compression stockings on the venous reflux in the lower limbs of pregnant women. Method A controlled randomized clinical trial was performed with sixty women: intervention group (n = 30), who used compression stockings, and control group (n = 30). Using duplex-ultrasound, the reflux time and peak reflux velocity in the great saphenous vein and small saphenous vein were analyzed. Results Great saphenous vein reflux times in the intervention group were 0.13 s at the beginning (initial) and 0.04 s at the end of pregnancy (final) in the right leg and 0.02 s and 0.34 s (p
