The ability of PI measurements to differentiate between acute rejection and ATN was investigated in 37 patients, who were frequently examined by duplex Doppler after kidney transplant. Absolute PI values as well as increase in PI were recorded and the clinical course was correlated with these pulsatility measurements. PI values were evaluated in 70% of patients undergoing acute rejection. However, in the majority of patients with ATN, the PI was evaluated from the start and continued to rise to an average of 8 days post-transplant. This rise in PI in patients with ATN suggests that pulsatility measurements are unreliable tests to differentiate acute rejection from ATN in the early post-transplant period.
对37例肾移植患者进行了研究，以探讨阻力指数（PI）测量在鉴别急性排斥反应和急性肾小管坏死（ATN）方面的能力，这些患者在肾移植后经常接受双功多普勒检查。记录了绝对PI值以及PI的升高情况，并将临床病程与这些搏动性测量结果进行关联。在70%发生急性排斥反应的患者中评估了PI值。然而，在大多数ATN患者中，从一开始就对PI进行评估，并且PI持续升高至移植后平均8天。ATN患者中PI的这种升高表明，在移植后的早期阶段，搏动性测量是区分急性排斥反应和ATN的不可靠测试。
