Two patients with non functioning silent kidney on excretory urography and renal artery occlusion on angiography, underwent renal artery revascularization without severe hypertension or renal failure. Angiographic appearance of collateral circulation, histologic evidence of intact viable glomeruli and a normal sized kidney are necessary for successful results. Renal blood flow was restored in the two patients but one had slight return of function and the other patient showed no evidence of improvement. Both patients presented criteria for revascularization. The first case was a minor success on the renal scintigraphy. The return of renal function did not occur in the second case because of preexisting renal pathology. We therefore recommend histologic examination before every renal artery revascularization for chronic occlusion.
两名患者排泄性尿路造影显示患有无功能静息肾，血管造影显示肾动脉闭塞，接受了肾动脉血运重建术，术后未出现严重高血压或肾衰竭。侧支循环的血管造影表现、完整存活肾小球的组织学证据以及正常大小的肾脏是取得成功结果的必要条件。两名患者的肾血流均得以恢复，但其中一名患者肾功能稍有恢复，另一名患者则无改善迹象。两名患者均符合血运重建标准。第一例在肾闪烁扫描方面取得了较小成功。第二例未出现肾功能恢复是因为存在既往肾脏病变。因此，我们建议在每次进行慢性闭塞性肾动脉血运重建术前进行组织学检查。
