我们之前已经证明，双功超声是诊断肾动脉狭窄的准确方法（与血管造影术相比，在诊断小于60%狭窄、60%至99%狭窄或闭塞方面的准确率为93%）。我们用这种方法连续观察了27例肾动脉狭窄60%~ 99%的35支肾动脉。15例患者的19支狭窄肾动脉未接受干预。肾脏尺寸显著减小（平均差异为-1.0 cm;p< 0.01;平均随访13个月），但所有19条肾动脉均保持通畅。对5例肾血管性高血压患者（6支肾动脉）进行了经皮腔内血管成形术（PTA）。肾双功扫描记录了2例PTA后高血压改善的患者的肾动脉狭窄缓解，并证实了3例PTA后高血压未改善的患者的残余60%至99%的肾动脉狭窄（平均随访6.5个月）。对7例10支狭窄的肾动脉行主动脉-肾动脉转流术。在平均随访9个月时，双功超声记录了8例通畅和2例闭塞的肾动脉旁路移植术。双功超声可用于确定未经治疗的肾动脉狭窄的自然史和评估肾动脉血管成形术或旁路术的结果。（J Vasc Surg1989;9：410-5.）
We have previously shown that duplex ultrasound is an accurate method of diagnosing renal artery stenosis (93% accuracy compared with angiography in the diagnosis of less than 60% stenosis, 60% to 99% stenosis, or occlusion). With this method we have now serially observed 35 renal arteries with 60% to 99% renal artery stenosis in 27 patients. Nineteen stenotic renal arteries in 15 patients were observed without intervention. There was a significant decrease in kidney size (mean difference − 1.0 cm;p< 0.01; mean follow-up 13 months) but all 19 renal arteries remained patent. Percutaneous transluminal angioplasty (PTA) was performed in five patients (six renal arteries) for renovascular hypertension. Renal duplex scanning documented relief of renal artery stenosis in two patients whose hypertension improved after PTA and confirmed residual 60% to 99% renal artery stenosis in three patients whose hypertension did not improve after PTA (mean follow-up 6.5 months). Aortorenal bypass was performed for 10 stenotic renal arteries in seven patients. At a mean follow-up of 9 months duplex ultrasound documented eight patent and two occluded aortorenal bypass grafts. Duplex ultrasound is useful both for defining the natural history of untreated renal artery stenosis and assessing the results of renal artery angioplasty or bypass. (J Vasc Surg1989;9:410–5.)
