A prognostic flowmetric study on 80 reconstructed arteries of the lower extremity was carried out to assess the flow wave patterns detected using a bidirectional doppler flowmeter. In 21 of 80 arteries, changes in the flow wave pattern were noted. For 10 of 21 affected arteries, an immediate arteriography revealed localized stenotic lesions at the distal anastomosis, in a short segment of the implanted autogenous vein graft or at the proximal host artery. Immediate repairs for the lesions were successfully performed by a minor surgery in 8 of 10 cases and the flow wave pattern reverted to normal. Two were not successful as the occlusion was complete before attempting the repair. The remaining 11 are now under conservative management as these patients refused further surgery. The ultrasonically driven flow wave pattern proved to be a useful indicator to assess the patency of the reconstructed peripheral artery to detect possible stenosis and thereby to take proper corrective measures and hence prevent a late occlusion.
对80条下肢重建动脉进行了一项预后血流测量研究，以评估使用双向多普勒流量计检测到的血流波形模式。在80条动脉中的21条中，注意到血流波形模式发生了变化。在21条受影响的动脉中的10条中，立即进行的血管造影显示在远端吻合口、植入的自体静脉移植物的短段或近端宿主动脉处有局部狭窄病变。在10例病例中的8例中，通过小型手术成功地对病变进行了即时修复，血流波形模式恢复正常。2例未成功，因为在尝试修复之前闭塞已完全形成。其余11例目前正在接受保守治疗，因为这些患者拒绝进一步手术。超声驱动的血流波形模式被证明是评估重建外周动脉通畅性、检测可能的狭窄并从而采取适当纠正措施以防止晚期闭塞的有用指标。
