Proximal propagation of an occlusive distal aortic thrombus to the suprarenal level is rare, probably resulting from diminished renal blood flow, and is invariably accompanied by renal failure. Three similar cases of total suprarenal aortic occlusion with renal failure are presented. In each, one kidney was significantly smaller than the other, probably caused by long-standing disease. The combination of bilaterally absent or markedly decreased femoral pulses with diminished renal function or a unilateral small kidney should therefore be considered dangerous. To prevent proximal propagation of thrombosis and death from renal failure, such patients should undergo arteriography and surgical repair promptly even though their clinical symptoms might be relatively mild and stable.
闭塞性远端主动脉血栓向肾上腺水平的近端蔓延很少见，可能是由于肾血流量减少所致，并且总是伴有肾衰竭。本文报告了3例类似的肾上腺水平完全性主动脉闭塞伴肾衰竭的病例。每例中，一侧肾脏明显小于另一侧，可能是由长期疾病引起的。因此，双侧股动脉搏动消失或明显减弱，同时伴有肾功能减退或单侧小肾，应视为危险情况。为防止血栓形成的近端蔓延和肾衰竭导致的死亡，即使这些患者的临床症状可能相对较轻且稳定，也应及时进行动脉造影和手术修复。
