21 patients with polytetrafluoroethylene grafts inserted for hemodialysis access were studied to assess the hemodynamic parameters. Mean graft flow was 1.9 l/min with a range of 0.2-3.8 l/min. Intragraft pressure varied from 1 to 83 mmHg and was dependent on systemic pressure, graft flow and the presence of stenotic lesions. Mean cardiac output was 7.1 l/min and index 4.0 l/min and was positively correlated with graft flow. By obtaining this data surgical corrective action was taken in several patients prospectively thus removing the abnormalities and ensuring continued graft patency. The techniques described are reproducible and simple and can be carried out in less than five minutes with minimal patient discomfort or hazard.
对21例为建立血液透析通路而植入聚四氟乙烯移植物的患者进行了研究，以评估血流动力学参数。移植物平均血流量为1.9升/分钟，范围为0.2 - 3.8升/分钟。移植物内压力在1至83毫米汞柱之间变化，且取决于全身压力、移植物血流量和狭窄病变的存在情况。平均心输出量为7.1升/分钟，心指数为4.0升/分钟，且与移植物血流量呈正相关。通过获取这些数据，前瞻性地对几名患者采取了手术纠正措施，从而消除了异常情况并确保移植物持续通畅。所描述的技术具有可重复性且操作简单，可在不到五分钟的时间内完成，对患者造成的不适或风险极小。
