The greater proportion of oxygen in the blood circulating in veins of the lower limbs bought to attention the possibility of pre-capillary arteriovenous shunting. The intra-arteriel injection of Technetium labelled serum albumin microspheres enables one to quantify arteriovenous shunts greater than 25 microns. The authors made a comparative study of arterio-venous shunting by blood gases analysis and isotopic techniques in twenty patients. The results seem to deny the existence of arteriovenous shunts in the genesis of essential varicose veins in the lower limb.
下肢静脉循环血液中较高比例的氧气引起了人们对毛细血管前动静脉分流可能性的关注。动脉内注射锝标记的血清白蛋白微球能够对直径大于25微米的动静脉分流进行定量。作者对20名患者采用血气分析和同位素技术对动静脉分流进行了对比研究。结果似乎否定了动静脉分流在下肢原发性静脉曲张发病机制中的存在。
