Table 6 The peak blood velocity of veins measured in elderly group (≥ 55 years old, n = 11)

From: Thigh-length graduated compression stocking cannot increase blood velocity of the common femoral vein in patients awaiting total hip arthroplasty

Velocity(cm/s) Without GCS With GCS P-value Alteration%
GSV peak velocity 10.1 ± 3.9 12.2 ± 8.1 0.39  + 20.8%
CFV peak velocity 16.9 ± 6.4 14.9 ± 5.9 0.08 -11.8%
Junction peak velocity 23.9 ± 11.7 23.4 ± 12.1 0.42 -2.1%
GSV mean velocity 5.9 ± 2.4 6.9 ± 4.4 0.48  + 16.9%
CFV mean velocity 9.2 ± 3.5 8.4 ± 3.4 0.08 -8.7%
Junction mean velocity 14.2 ± 7.2 13.8 ± 7.4 0.53 -2.8%
  1. Values are mean with SD
  2. GSV Great saphenous vein, CFV Common femoral vein, Junction the junction of GSV and CFV
