In six patients in whom a femoro-popliteal vein bypass graft was performed for intermittent claudication, the relationship between the haemodynamic state of the leg and the femoral venous oxygen saturation before and after local vasodilatation was investigated. The study was undertaken with special reference to the known influence of hypovolaemia on the leg blood flow. It is concluded that a femoral venous oxygen saturation below 70%indicates that the leg blood flow is less than 200 ml/min and that the bypass flow is less than 100 ml/min and thus within a range in which the incidence of early thrombosis is high. Furthermore, an increase in femoral venous oxygen saturation of 10% or more on local vasodilatation indicates a state of hypovolaemia, necessitating further blood substitution.
对6例因间歇性跛行而行股-腘静脉搭桥术的患者，研究了局部血管扩张前后腿部血流动力学状态与股静脉血氧饱和度之间的关系。本研究特别参考了已知的低血容量对腿部血流的影响。得出的结论是，股静脉血氧饱和度低于70%表明腿部血流小于200毫升/分钟，搭桥血流量小于100毫升/分钟，因此处于早期血栓形成发生率较高的范围内。此外，局部血管扩张时股静脉血氧饱和度增加10%或更多表明处于低血容量状态，需要进一步补充血液。
