摘要
目的探讨肾动脉小慢波频谱联合超声心动图对成人型主动脉缩窄的临床价值。方法回顾性分析12例成人型主动脉缩窄的临床资料,评价肾动脉小慢波频谱联合超声心动图对其的临床价值。结果试验组和对照组在肾动脉收缩期峰值流速、加速时间、阻力指数方面差异有统计学意义(P<0.05)。肾动脉小慢波频谱联合超声心动图诊断成人型主动脉缩窄11例,漏诊1例,超声诊断符合率为91.66%。12例成人型主动脉缩窄合并主动脉瓣二瓣化畸形2例、动脉导管未闭1例,余为孤立性主动脉缩窄。结论肾动脉小慢波频谱可以作为一种间接征象,提示存在主动脉缩窄,联合超声心动图可以明确狭窄部位,以及是否合并心内畸形,具有一定的临床价值。
Objective To investigate the clinical value of tardus-parvus pattern spectrum of renal artery combined with echocardiography in adult aortic coarctation.Methods The clinical data of 12 cases of adult aortic coarctation were retrospectively analyzed,and the clinical value of tardus-parvus pattern spectrum of renal artery combined with echocardiography was evaluated.Results There were significant differences in peak systolic velocity,acceleration time and resistance index between groups(P<0.05).Eleven cases of adult aortic coarctation were diagnozed by tardus-parvus pattern spectrum of renal artery combined with echocardiography,and one case was missed.The coincidence rate of ultrasonic diagnosis was 91.66%.There were 12 cases of adult aortic coarctation combined with aortic valve binarization in two cases,patent ductus arteriosus in one case,and the rest were isolated aortic coarctation.Conclusion The tardus-parvus pattern spectrum of renal artery can be used as an indirect sign to indicate the presence of aortic coarctation.Combined with echocardiography,the site of stenosis can be determined,and whether it is complicated with intracardiac malformation.The result has certain clinical value.
