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.
