探究超声心动图诊断胎儿肺动脉狭窄的产前及产后对照

To Explore the Contrast Between Prenatal and Postpartum Echocardiography in the Diagnosis of Fetal Pulmonary Artery Stenosis

目的:探讨在产前、产后胎儿肺动脉狭窄诊断中使用超声心动图诊断的价值。方法:在2010年4月~2019年10月来本院就诊的疑似胎儿肺动脉狭窄患者中,选取30例进行统计分析,对比产前、产后胎儿肺动脉狭窄的超声心动图结果。结果:30例疑似胎儿肺动脉狭窄患者中,行超声心动图诊断,结果显示有18例胎儿存在肺动脉狭窄情况,其占比为60.00%(18/30),相比于产前诊断结果,组间差异性明显(P<0.05)。18例胎儿中,有12例为肺动脉瓣狭窄胎儿,占比为66.67%(12/18);有6例肺动脉主干狭窄胎儿,占比为33.33%(6/18),2种情况相比组间差异性明显(P<0.05)。在肺动脉瓣狭窄的患者中有5例患者为轻度狭窄,占41.67%。有2例患者为中度狭窄,占16.67%。有5例患者为重度狭窄,占41.67%。在肺动脉主干狭窄的患者中有2例为重度狭窄,占33.33%。有4例为中度狭窄,占66.67%。结论:在产前、产后胎儿肺动脉狭窄诊断中使用超声心动图诊断,其诊断准确率较高,同时也可以提升疾病进展的准确程度,具有较高的临床应用价值。

Objective:To evaluate the value of echocardiography in the diagnosis of pulmonary artery stenosis before and after delivery.Methods:From April 2010 to October 2019,30 patients with suspected fetal pulmonary artery stenosis were selected for statistical analysis,and the echocardiography results of fetal pulmonary artery stenosis before and after delivery were compared.Results:Echocardiography was performed in 30 patients with suspected fetal pulmonary artery stenosis.The results showed that 18 fetuses had pulmonary artery stenosis,accounting for 60.00%(18/30).Compared with the results of antenatal diagnosis,there was significant difference between the two groups(P<0.05).Of the 18 fetuses,12 had pulmonary valve stenosis(66.67%)(12/18)and 6 had pulmonary artery trunk stenosis(33.33%)(6/18).Compared with the two cases,the difference between the groups was obvious(P<0.05).Among patients with pulmonary valve stenosis,5 patients had mild stenosis,accounting for 41.67%.2 patients had moderate stenosis,accounting for 16.67%.There were 5 patients with severe stenosis,accounting for 41.67%.In patients with pulmonary artery stenosis,2 cases were severe stenosis,accounting for 33.33%.There were 4 cases of moderate stenosis,accounting for 66.67%.Conclusion:The use of echocardiography in the diagnosis of fetal pulmonary artery stenosis before and after childbirth has a high diagnostic accuracy rate and can also improve the accuracy of disease progression,which has high clinical application value.
