Lumbar sympathectomy increases total limb blood flow after aortofemoral bypass in a high percentage of cases. This was true in eleven of fourteen extremities (78.6 per cent) in our series even though no specific selection criteria for entry into the study, other than the need for aortofemoral bypass, were used: that is, patients were entered into the study irrespective of preoperative ankle/arm pressure indexes or results of hyperemia testing. Overall, flow rates after sympathectomy was added to aortofemoral bypass were 1.55 times greater than after aortofemoral bypass alone. This degree of augmentation of flow may be important, particularly in cases of limited outflow.
在大多数情况下，腰交感神经切除术可增加主动脉股动脉旁路移植术后肢体的总血流量。在我们的研究系列中，14个肢体中的11个（78.6%）都是如此，尽管除了需要进行主动脉股动脉旁路移植术外，没有使用其他特定的入选标准：也就是说，无论术前踝/臂压力指数或充血试验结果如何，患者都被纳入研究。总体而言，在主动脉股动脉旁路移植术基础上加做腰交感神经切除术后的血流量比单纯主动脉股动脉旁路移植术后增加了1.55倍。这种血流量的增加程度可能很重要，特别是在流出道受限的情况下。
