Abdominal aortic coarctation is a rare, non-atherosclerotic disease. It is a functionally significant at an early age when associated with aortic branch stenosis and renovascular hypertension. The pathogenesis of aortic constrictive lesions remains unknown, but may be related to developmental error or aortic growth arrest and various hypotheses have been reported. When the renal arteries are involved by the coarctation, severe hypertension is common at an early age and in untreated patients, life-threatening complications commonly occur. Patients who reach the age of 40 years generally have the coarctation below the renal arteries but even when the renal arteries are not involved by the coarctation, renovascular disease may still occur due to secondary atherosclerosis. Aortic thrombosis secondary to abdominal aortic coarctation with renovascular disease and lower limb ischemia, occurring in a 63-year old woman, is reported.
腹主动脉缩窄是一种罕见的非动脉粥样硬化性疾病。在早年，当它与主动脉分支狭窄和肾血管性高血压相关时，具有显著的功能意义。主动脉缩窄性病变的发病机制尚不清楚，但可能与发育异常或主动脉生长停滞有关，并且已有各种假说报道。当肾动脉被缩窄累及，早年常见严重高血压，未经治疗的患者通常会出现危及生命的并发症。活到40岁的患者缩窄通常位于肾动脉以下，但即使肾动脉未被缩窄累及，由于继发性动脉粥样硬化仍可能发生肾血管疾病。本文报道了一名63岁女性患者，因腹主动脉缩窄继发肾血管疾病和下肢缺血导致主动脉血栓形成。
