Renal atrophy due to the renal artery stenosis associated with aortitis syndrome was studied in seven patients. Severe hypertension, high plasma renin activity and normal overall renal functions were present in all. The luminal diameter of the stenosed renal artery seen on the angiogram was less than 1.5 mm at the maximum area of stenosis in all patients. The size of the kidney with renal artery stenosis was diminished, ranging from 8.0 to 14.0 cm in longitudinal diameter on the nephrogram. Histological findings of the small kidney revealed ischemic atrophy. Although the rate of progression of the arterial stenosis was uncertain, the collateral circulation was found to be rich. Renal atrophy was not frequent and not marked even in the presence of high grade renal stenosis or obstruction in case of renovascular hypertension secondary to the arteritis.
对7例与大动脉炎综合征相关的肾动脉狭窄所致肾萎缩患者进行了研究。所有患者均有严重高血压、高血浆肾素活性及正常的总体肾功能。血管造影显示，所有患者狭窄肾动脉在狭窄最大处的管腔直径均小于1.5mm。肾动脉狭窄侧肾脏体积缩小，肾图显示其纵径为8.0至14.0cm。小肾脏的组织学表现为缺血性萎缩。虽然动脉狭窄的进展速度不确定，但发现侧支循环丰富。在动脉炎继发的肾血管性高血压患者中，即使存在高度肾狭窄或梗阻，肾萎缩也不常见且不明显。
