The role of noninvasive hemodynamic tests in the evaluation of percutaneous transluminal angioplasty success or failure was studied. The ankle-brachial pressure index and pulse volume recording amplitude were measured before and after 37 iliac and 46 femoropopliteal angiographically successful percutaneous transluminal angioplasties. Immediate evidence of hemodynamic improvement was seen in 53 percent of angiographically successful dilatations using the ankle-brachial pressure index and in 60 percent using the pulse volume recording amplitude alone. A better correlation was seen when improvement was noted on either test but was still only 71 percent. Twelve primary iliac percutaneous transluminal angioplasties were considered to be successful immediately by angiography, yet no hemodynamic improvement was recorded. Nine primary iliac percutaneous transluminal angioplasties, however, had continued clinical success and limb viability. Twelve angiographically successful femoropopliteal percutaneous transluminal angioplasties also showed no improvement in hemodynamic values, yet three have continued clinical evidence of patency. Thus, although noninvasive hemodynamic tests are important and must be carried out, they are only one of many ways to assess the effectiveness of angioplasty.
研究了无创血流动力学检测在评估经皮腔内血管成形术成功或失败中的作用。在37例髂动脉和46例股腘动脉经血管造影证实成功的经皮腔内血管成形术前和术后，测量了踝臂压力指数和脉搏容积记录幅度。在经血管造影证实成功的扩张术中，使用踝臂压力指数时，53%的患者有血流动力学改善的即时证据；仅使用脉搏容积记录幅度时，60%的患者有血流动力学改善的即时证据。当两项检测中任何一项显示有改善时，相关性更好，但仍仅为71%。12例原发性髂动脉经皮腔内血管成形术经血管造影立即判定为成功，但未记录到血流动力学改善。然而，9例原发性髂动脉经皮腔内血管成形术在临床上持续成功且肢体存活。12例经血管造影证实成功的股腘动脉经皮腔内血管成形术也未显示血流动力学值有改善，但其中3例在临床上仍有通畅的证据。因此，尽管无创血流动力学检测很重要且必须进行，但它们只是评估血管成形术有效性的众多方法之一。
