The predictive value of noninvasive Doppler arterial evaluation was assessed in 42 limbs before and after aortofemoral bypass for severe limb ischemia. The preoperative ankle-brachial systolic index was not of predictive value for the need of further distal reconstructin. A postoperative increase of ankle index by 0.1, or more, indicatd that, probably, no additional distal reconstruction would be necessary. Two-thirds of the limbs in which the ankle index did not improve by 0.1 required further distal bypass. Perioperative noninvasive arterial evaluation is helpful in supplementing clinical assessment and angiograpic data in the decision-making for, or against, distal bypass following aortofemoral bypass for limb salvage.
在42例因严重肢体缺血而行主-股动脉搭桥术的患者中，评估了无创多普勒动脉评估在术前和术后的预测价值。术前踝肱收缩压指数对是否需要进一步进行远端血管重建并无预测价值。术后踝指数升高0.1或更多，可能表明无需进行额外的远端血管重建。踝指数未升高0.1的肢体中有三分之二需要进一步进行远端搭桥术。围手术期无创动脉评估有助于补充临床评估和血管造影数据，以决定是否在主-股动脉搭桥术后进行远端搭桥术以挽救肢体。
