We performed a prospective randomised controlled trial of a new mechanical method of prophylaxis for venous thrombo-embolism in 60 patients undergoing knee replacement surgery. The method uses the A-V Impulse System to produce cyclical compression of the venous reservoir of the foot. The overall incidence of deep-vein thrombosis was 68.7% in patients receiving no prophylaxis and 50% in those using the device. The difference was not significant. There was, however, a reduction of the extent of thrombosis in the treated group. There were 13 major calf-vein thrombi and six proximal-vein thrombi in the control group compared with only five major calf-vein thrombi in the treated group. This difference was significant (p = 0.014). No patient developed clinical features of a pulmonary embolism.
我们对60例接受膝关节置换手术的患者进行了一项前瞻性随机对照试验，以研究一种预防静脉血栓栓塞的新机械方法。该方法使用动静脉脉冲系统对足部静脉储血器进行周期性压迫。未接受预防措施的患者深静脉血栓形成的总体发生率为68.7%，使用该装置的患者为50%。差异不显著。然而，治疗组的血栓形成范围有所减少。对照组有13个主要小腿静脉血栓和6个近端静脉血栓，而治疗组只有5个主要小腿静脉血栓。这种差异具有显著性（p = 0.014）。没有患者出现肺栓塞的临床症状。
