胎儿永存动脉干的产前超声诊断

目的 探讨超声心动图产前诊断胎儿永存动脉干的临床价值.方法 对57例永存动脉干胎儿超声心动图资料进行回顾性分析总结.结果 产前诊断胎儿永存动脉干57例,37例经产后病理证实(其中5例为法洛四联症),2例经产后超声心动图确诊,18例失访.胎儿永存动脉干的主要声像图特征是室间隔缺损,心脏只发出1支大动脉和肺动脉起源于干动脉.结论 超声心动图产前诊断胎儿永存动脉干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.

Prenatal diagnosis and antenatal history of persistent truncus arteriosus: A case report

We report the prenatal diagnosis and the natural history of a fetus with truncus arteriosus. A 31-year-old woman, gravida 3, was referred for detailed examination for suspected cardiac anomaly during her 33rd week of gestation. Fetal echocardiography demonstrated a large truncal vessel overriding a ventricular septal defect, a right-side aortic arch, and a dilated ascending aortic arch. Pulsed-wave and color-flow Doppler imaging showed truncal valvular stenosis without insufficiency. No sign of congestive heart failure was detected during the prenatal period. A fetus weighing 2860 grams was delivered during the 38th week of gestation. Cyanosis was noted the day after delivery, however, and a Rastelli procedure was carried out 9 days after delivery. The baby died 7 days after the operation.     

Prenatal sonographic diagnosis of truncus arteriosus associated with holoprosencephaly

We present the case of a truncus arteriosus associated with holoprosencephaly detected in a fetus in the first trimester and the sonographic findings that established this diagnosis. A physical exam was performed on a 35-year-old pregnant woman, gravida 2, para 1. At 20 weeks, sonography showed large-for-date uterine size. Fetal biometry was consistent with menstrual age. Amniotic fluid volume was elevated to 25 AFI cm. Fetal echocardiography revealed a single common artery arising from the heart, a ventricular septal defect, and other cardiac defects. Abnormalities of the fetal brain and face were also shown via sonography, including the presence of a common lateral ventricle without falx cerebri. Alobar holoprosencephaly, the most severe form of holoprosencephaly, was diagnosed. Prenatal chromosomal analysis was offered and the patient elected to have cordocentesis. The chromosome study was normal. Success in surgical repair of truncus arteriosus is established, but alobar holoprosencephaly is associated with neonatal death. Continuation of the pregnancy carried risks for the mother. After proper counseling, the parents of this fetus were offered and accepted termination of pregnancy. A male abortus weighing 320 grams was delivered. Postnatal findings and autopsy confirmed the diagnosis.     

Prenatal sonographic appearance of truncus arteriosus on wide‐band Doppler imaging

Persistent truncus arteriosus is an uncommon congenital cardiac anomaly. In most patients, this condition is not diagnosed prior to birth. We report a case in which this uncommon cardiac anomaly was diagnosed prenatally using wide‐band Doppler imaging. When diagnosing fetal truncus arteriosus, sonologists should carefully search for the origin of the main pulmonary artery and for its 2 branches. Our experience suggests that wide‐band Doppler imaging facilitates the prenatal diagnosis of truncus arteriosus. © 2008 Wiley Periodicals, Inc. J Clin Ultrasound, 2009
