Abstract:

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.
