目的:探讨产前超声检查诊断胎儿右室双出口的临床价值。方法:对20例右室双出口胎儿超声心动图资料进行回顾性分析总结。结果:产前诊断胎儿右室双出口20例,11例引产后病理证实,1例产后病理证实为完全性大动脉转位,1例产后经超声心动图确诊,余7例失访。结论:胎儿右室双出口的声像图特征:主动脉、肺动脉根部平行排列且均发自右心室。超声心动图产前诊断胎儿右室双出口具有重要的临床价值,但应注意与多种胎儿复杂心脏病鉴别。
Objective: To investigate the clinical value of prenatal ultrasound in the diagnosis of double outlet of fetal right ventricle. Methods: The echocardiographic data of 20 patients with right ventricle and double outlet were analyzed retrospectively. Results: Prenatal diagnosis of fetal right ventricular double outlet in 20 cases, 11 cases of postpartum pathology confirmed, 1 postpartum pathology confirmed complete transposition of the artery, 1 postpartum confirmed by echocardiography, and 7 cases were lost. Conclusion: The fetal right ventricular double outlet sonographic features: the aorta, pulmonary roots arranged in parallel and are from the right ventricle. Echocardiography Prenatal diagnosis of fetal right ventricular double outlet has important clinical value, but should pay attention to a variety of fetal heart disease and complex identification.
