Aim: To quantify the haemodynamic effect according to pneumatic intermittent compression (PIC) in venous oedema using the veno-arterial flow index (VAFI). Methods: In 33 patients (C3-6 EP,S, A S,D,P, PO,R) with venous oedema in spite of compression therapy and 20 healthy volunteers the ratio of volume flow in the common femoral vein and artery (VAFI) was calculated before (VAFI-0), 30 min (VAFI-1) and 2 h after PIC. One week after 19 PIC performed 2 or 3 times per week VAFI-20 was measured. Results: VAFI-0 was 1.49 ± 0.29 in venous oedema and 0.87 ± 0.07 in healthy limbs (p <0.001). After PIC VAFI decreased significantly to 0.96 ± 0.25 (VAFI-1). VAFI-2 amounted to 1.07 ± 0.15 and VAFI-20 remained stable at 1.07 ± 0.18. In healthy limbs VAFI did not change according to PIC (p = 0.40). Conclusion: In venous oedema persisting in spite of compression therapy additional PIC significantly improves venous haemodynamics as quantified by VAFI-measurement.
