Coarctation of the aorta is a common cardiovascular disorder with an unknown etiology. In the preductal type, blood flows from a patent ductus into the distal aorta. When the coarctation is juxtaductal or postductal, blood flows to the lower extremities by way of the subclavian arteries and collaterals. Plain films may show the reverse sign in postductal coarctation. Arteriography is the gold standard for making the diagnosis. However, magnetic resonance imaging will probably become an increasingly important diagnostic tool. The treatment of choice is surgery, with complete resection of the stenosed segment.
主动脉缩窄是一种常见的病因不明的心血管疾病。在导管前型中，血液从动脉导管流入主动脉远端。当缩窄位于导管旁或导管后时，血液通过锁骨下动脉和侧支循环流向下肢。平片在导管后缩窄时可能显示反向征。动脉造影是诊断的金标准。然而，磁共振成像可能会成为一种越来越重要的诊断工具。首选的治疗方法是手术，完全切除狭窄段。
