To clarify the effects to lower extremity venous hemodynamics of simultaneous use of elastic stocking (ES) and intermittent pneumatic compression system (IPC), blood flow velocity was evaluated by duplex scanning. Twelve limbs in 6 volunteers without evidence of venous disease were studied. IPC device (Ven Assist model VA-1000 (ACI Medical, USA)) with a foot and calf cuff and ES (Comprinet pro, Terumo•BNS, Hamburg) were used.Measurements were obtained in supine position from the common femoral vein and the great saphenous vein. Peak venous velocity was significantly increased by IPC (p<0.01) and was not significantly changed by ES alone in the common femoral vein and in the great saphenous vein. By simultaneous use of IPC and ES, peak venous velocity was not increased and acceleration time was found to be significantly lower than by ICP alone (p<0.05). In conclusion, the simultaneous use of IPC and ES does not increase peak velocity of compressed wave in the common femoral vein and the great saphenous vein. However, further studies are necessary to evaluate the prophylactic effects for preventing deep vein thrombosis.
