超声心动图联合64排CT心血管造影在法洛四联症诊断中的应用研究

The Application of Combination of Transthoracic Echocardiography and 64-slice Spiral CT Angicardiography in Diagnosis on Tetralogy of Fallot

    摘要
  • 摘要: 目的:通过对比单纯超声心动图和超声心动图联合64排CT心血管造影对肺动脉狭窄部位的诊断准确性,对肺动脉主干、左、右肺动脉内径、右心室流出道内径以及患儿肺血管发育情况的预测准确率,并通过相关性分析说明超声心动图和64排CT心血管造影两种方法对左右心室各指标测量结果的密切相关性,从而阐明联合应用两种方法在提高法洛四联症心血管成像诊断准确率中的重要意义。方法:分别采用超声心动图和超声心动图联合64排CT心血管造影诊断肺动脉狭窄部位以及评价患儿肺血管发育情况,并与手术后实际诊断结果比较;采用超声心动图和超声心动图联合64排CT心血管造影测量肺动脉主干、左、右肺动脉内径以及右心室流出道内径,并与手术后实际测得结果比较;相关性分析说明超声心动图和64排CT心血管造影两种方法对左右心室各指标测量结果的相关情况。结果:超声心动图联合64排CT心血管造影诊断肺动脉狭窄部位的准确率为91.5%,明显高于单纯超声心动图的准确率68.1%(<i<P</i<<0.05);联合诊断组所测得Me Goon指数、Nakata指数、肺动脉主干、左、右肺动脉内径以及右心室流出道内径与手术组实测结果间无明显统计学差异(<i<P</i<<0.05),而超声心动图与手术实测结果相比有明显统计学差异(<i<P</i<<0.05);超声心动图和64排CT心血管造影对左右心室各指标测量结果均呈现密切相关性(<i<r</i<<0.7,<i<P</i<<0.05)。结论:单纯超声心动图和64排CT心血管造影在诊断法洛四联症病变方面呈现密切相关性,但超声心动图联合64排CT心血管造影对法洛四联症(TOF)病变情况的诊断准确率明显高于单纯超声心动图,为临床上法洛四联症心血管成像提供了新的思路。

     

    Abstract: Objective: To compare the diagnostic accuracy in pulmonary stenosis, the main pulmonary artery, left, right pulmonary artery, the right ventricular outflow tract inner diameter and pulmonary vascular development situation between Transthoracic Echocardiography(ECG) and the combination of Transthoracic Echocardiography and 64-slice Spiral CT Angicardiography(ACG), analyze the closely correlation between ECG and 64-slice Spiral CT ACG in left and right heart chamber indexes by correlation analysis so that we can illustrate the important value in the application of the combination of ECG and 64-slice Spiral CT ACG in TOF diagnosis accuracy. Methods: ECG and ECG combined with 64-slice Spiral CT ACG were used to diagnose the pulmonary stenosis area and evaluate pulmonary vascular development situation, and then made comparison with the actual diagnosis after surgery; ECG and ECG combined with 64-slice Spiral CT ACG were used to measure the main pulmonary artery, left, right pulmonary artery and the right ventricular outflow tract inner diameter, and then made comparison with the actual diagnosis after surgery; Correlation analysis was used to analyze the correlation between ECG and 64-slice Spiral CT ACG in left and right heart chamber indexes. Results: The diagnostic accuracy in pulmonary stenosis in ECG combined with 64-slice Spiral CT ACG group was 91.5%, which was higher than ECG group's 68.1%(<i<P</i<<0.05); There were no significant differences in Me Goon index, Nakata index, the main pulmonary artery, left, right pulmonary artery, the right ventricular outflow tract inner diameter between ECG combined with 64-slice Spiral CT ACG group and actual diagnosis after surgery group(<i<P</i<<0.05); There was closely correlation between ECG and 64-slice Spiral CT ACG in left and right heart chamber indexes by correlation analysis(<i<r</i<<0.7, <i<P</i<<0.05). Conclusions: There was closely correlation between ECG and 64-slice Spiral CT ACG in diagnosis of TOF, the diagnostic accuracy of TOF is higher in ECG combined with 64-slice Spiral CT ACG group than the ECG group which provides a new train of thought in tetralogy of TOF.
