【摘要】目的 探讨超声诊断主动脉缩窄(COA)的临床价值。方法 选取我院2007年7月~2010年12月收治的78例主动脉缩窄患者的临床资料，所有患者均经过超声诊断，并经过手术或者心血管造影(CAG)确诊，总结主动脉缩窄的超声表现，并对超声检查对诊断主动脉缩窄的临床价值进行评价。结果 在本组患者中有58例患者诊断符合，诊断符合率为74.36%。在本组患者中有33例患者胸骨上窝探查可见主动脉起始部，左锁骨下动脉开口处远端的将主动脉内径变细，12例患者为局限性狭窄，缩窄段管壁增厚，回声增强，降主动脉不同程度扩张，13例患者为管性狭窄。超声测量COA内径值与手术或者CAG比较差异无统计学意义(p<0.05)；超声测量COA长度与手术或者CAG比较差异有统计学意义(p>0.05)。结论 超声诊断COA的诊断正确率不及CAG，但是作为一种无创性检查方法可以在临床推广。

【Abstract】Objective To evaluate the ultrasound diagnosis of aortic coarctation (COA) of the clinical value. Methods The hospital in July 2007 ~ December 2010 78 patients with coarctation of the aorta in patients with clinical data, all the patients after diagnosis, and after surgery, or cardiac angiography (CAG) confirmed, reduced aortic Summary narrow ultrasonography, and ultrasonography in the diagnosis of coarctation of the aorta to evaluate the clinical value. Results In this group of patients, 58 patients in the diagnosis, diagnostic accuracy rate was 74.36%. In this group of patients, 33 patients with aortic suprasternal fossa exploration shows the beginning part of the left subclavian artery to aortic diameter distal opening thinner and 12 patients were the limitations of the narrow, narrow section of wall thickening echo enhancement, different degrees of expansion of the descending aorta, 13 patients with canal stenosis. COA diameter values measured by ultrasound surgery or no significant difference between the CAG (p <0.05); ultrasound measurement COA surgery or CAG length was statistically significant difference (p> 0.05). Conclusion Ultrasound diagnosis of COA's diagnostic accuracy is less than CAG, but as a noninvasive method in clinical practice.
