孕妇,32岁,孕3产1。孕33~(+3)周超声检查示:彩色多普勒示右心室近肺动脉瓣环下方可探及异常束状血流信号,宽2mm,追踪异常血流信号起源于近肺动脉瓣下的右室前壁,另于大动脉短轴略偏向头侧斜切面可探及左冠状动脉内血流信号与之相连(图1),频谱多普勒以舒张期为主的双期单向血流频谱(图2)。超声提示:胎儿左冠状动脉右室瘘可能。出
Pregnant women, 32 years old, pregnant 3 produce 1. Pregnancy 33 ~ (+3) weeks ultrasonography showed: color Doppler showed right ventricular near the pulmonary valve ring below the probe and abnormal bundle-shaped blood flow signal, width 2mm, tracking abnormal blood flow signals originated in the right pulmonary valve near the right ventricle The anterior wall, and the other short axis of the aorta slightly biased to the head side of the oblique surface can be explored and connected to the left coronary artery blood flow signal (Figure 1), the spectrum of Doppler to diastolic predominant biphasic unilateral blood flow spectrum ( figure 2). Ultrasound Tip: Fetal left coronary artery may be right ventricular fistula. Out
