Two cases of thoracic aortic coarctation seen on the suprasternal incidence of bidimensional echocardiography are reported. In one case, the observed echocardiographic image is an obstruction of the vascular lumen. In the other there is only reduction of the vascular calibre. In both cases, a complete examination of the aortic arch and its major branches, substrictural aortic region, and cardiac valves was obtained. The echographic results were concordant with those of the angiography, except for an underestimation of the severity of the thoracic stenosis in the second case, with the echography. An echographic post-operative control in the first case showed normalization of the vascular calibre in the isthmus region. Echocardiography allows visualization of thoracic aortic coarctations and examination of associated vascular and cardiac lesions. However, problems remain in the quantification of stenosis, which are inherent to the technique.
报道了两例经胸骨上窝二维超声心动图检查发现的胸主动脉缩窄病例。在一例中，观察到的超声心动图图像为血管腔梗阻。在另一例中，仅血管口径减小。在这两例中，均对主动脉弓及其主要分支、缩窄下方的主动脉区域以及心脏瓣膜进行了全面检查。超声心动图结果与血管造影结果一致，只是第二例中超声心动图低估了胸段狭窄的严重程度。第一例术后超声心动图检查显示峡部区域血管口径恢复正常。超声心动图可显示胸主动脉缩窄并检查相关的血管和心脏病变。然而，该技术在狭窄定量方面仍存在问题。
