There are conflicting reports in the literature about the existence of arteriovenous shunting in legs with chronic venous insufficiency. Using duplex scanning, we have earlier shown that there is lowered peripheral resistance in the arteries of legs with venous ulcer together with premature venous filling in angiography. In the present study we investigated the peripheral resistance in the arteries of 16 legs with chronic venous insufficiency without present ulcer. We compared the results with those obtained from 12 healthy legs and from 18 legs with venous ulcer. There was a highly significant inverse correlation between the severity of chronic venous insufficiency and the peripheral resistance in the popliteal, the dorsal pedal and the posterior tibial arteries (p < 0.001). These results suggest that there is arteriovenous shunting in legs with chronic venous insufficiency and that this phenomenon correlates with the degree of chronic venous insufficiency.
关于慢性静脉功能不全患者腿部动静脉分流的存在，文献中有相互矛盾的报道。我们之前通过双功扫描显示，患有静脉溃疡的腿部动脉外周阻力降低，同时血管造影显示静脉过早充盈。在本研究中，我们调查了16条无溃疡的慢性静脉功能不全患者腿部动脉的外周阻力。我们将结果与12条健康腿部以及18条患有静脉溃疡的腿部的结果进行了比较。慢性静脉功能不全的严重程度与腘动脉、足背动脉和胫后动脉的外周阻力之间存在高度显著的负相关（p < 0.001）。这些结果表明，慢性静脉功能不全患者的腿部存在动静脉分流，并且这种现象与慢性静脉功能不全的程度相关。
