Seventy-five limbs of 66 patients undergoing arterial reconstruction of the lower extremity were studied. In 41 of 64 limbs that were not involved in early failure, API returned to normal immediately and the increased API was maintained as long as grafts remained patent. The limbs exhibiting a rise in API of 0.1 or more following proximal reconstruction in the cases with combined iliac and femoral arterial occlusion or bypass grafting to an isolated segment obtained marked improvement of symptoms. Postoperative increase in TPI was not so marked as in API, and TPI remained very low in the limbs with arterial obstructive lesions below the ankle after successful reconstruction. Early or late failure could not be predicted on the basis of preoperative or postoperative API, TPI or A-T gradient. In the limbs with no recovery of TPI, blood flow or flow velocity in the foot was of value predicting which limbs would be salvaged.
对66例接受下肢动脉重建术患者的75条肢体进行了研究。在64条未出现早期失败的肢体中，有41条肢体的踝肱指数（API）立即恢复正常，并且只要移植物保持通畅，升高的API就会维持。在髂股动脉联合闭塞或旁路移植至孤立节段的病例中，近端重建后踝肱指数升高0.1或更多的肢体症状得到明显改善。术后经皮氧分压（TPI）的升高不如踝肱指数明显，并且在成功重建后，踝关节以下存在动脉阻塞性病变的肢体中，经皮氧分压仍然非常低。无法根据术前或术后的踝肱指数、经皮氧分压或踝肱梯度预测早期或晚期失败。在经皮氧分压未恢复的肢体中，足部的血流或流速对于预测哪些肢体能够挽救具有价值。
