Functional impairment, aneurysma formation, and restenosis are well known complications after surgery for coarctation of the aorta. In order to assess long-term results, 25 adults were studied by physical examination, exercise tests, and magnetic resonance imaging after an interval ranging from 1 to 28 years since surgery for coarctation. Fifteen patients had arterial hypertension at rest, five additional patients showed hypertension on exertion only. Magnetic resonance imaging showed pathological changes of the aorta in all patients. An aneurysm of the ascending aorta was seen in four patients, a circumscript aneurysm in the descending aorta at the site of surgery was found in three patients. Restenosis of the descending aorta occurred in three patients. In eight patients the left subclavian artery was distally displaced and dilated in eleven patients. In order to initiate appropriate treatment of specific complications such as restenosis, aneurysm, and arterial hypertension, regular checks are necessary in patients with surgery for aortic coarctation. In addition to clinical examination and exercise tests, magnetic resonance imaging is an effective noninvasive imaging method for follow-up.
功能障碍、动脉瘤形成和再狭窄是主动脉缩窄手术后众所周知的并发症。为了评估长期结果，对25名成年人进行了研究，这些患者在主动脉缩窄手术后1至28年的间隔期后接受了体格检查、运动测试和磁共振成像检查。15名患者静息时患有动脉高血压，另外5名患者仅在运动时出现高血压。磁共振成像显示所有患者的主动脉均有病理改变。4例患者发现升主动脉瘤，3例患者在手术部位的降主动脉发现局限性动脉瘤。3例患者出现降主动脉再狭窄。8例患者左锁骨下动脉向远端移位，11例患者左锁骨下动脉扩张。为了对再狭窄、动脉瘤和动脉高血压等特定并发症启动适当的治疗，对接受主动脉缩窄手术的患者进行定期检查是必要的。除了临床检查和运动测试外，磁共振成像是一种有效的无创随访成像方法。
