| 目的 分析先天性冠状动脉瘘的产前超声图像特征，总结其预后及转归。方法 回顾性分析我院产前超声检出的7例先天性冠状动脉瘘胎儿的检查资料，总结其产前超声表现，随访其临床结局。结果 产前超声诊断的7例先天性冠状动脉瘘胎儿中，孤立性冠状动脉瘘3例，合并其他畸形4例；4例为左冠状动脉瘘，3例为右冠状动脉瘘。二维超声表现：7例于左室流出道切面主动脉根部可见受累的冠状动脉显示不同程度的增宽扩张，内径2.5～4.4 mm；2例于四腔心切面可见左、右心不对称，左心偏小，其余5例基本对称。CDFI表现：7例胎儿主动脉根部或房室沟等区域探及管状异常湍流血流信号。临床结局：2例孤立性冠状动脉瘘出生后手术效果好；1例合并肺动脉狭窄、室间隔缺损及心包积液，孕37周胎死宫内；4例引产。结论 应用产前超声发现主动脉根部或房室沟等切面探及异常明亮的管状血流信号时，通过追踪其起源、走行及终点后需警惕冠状动脉瘘可能，对胎儿出生后早期治疗具有重要的临床价值。 |

| Abstract: |
| Objective To analyze the characteristics of prenatal ultrasound images of congenital coronary artery fistula and summarize its prognosis and outcome.
Methods The clinical information and ultrasonic data of 7 fetuses with congenital coronary artery fistula in our hospital were analyzed retrospectively. The prenatal ultrasound findings were summarized and the clinical outcomes were followed up. Results Among the 7 fetuses with congenital coronary artery fistula diagnosed by prenatal ultrasound, 3 cases had isolated coronary artery fistula and 4 cases had other malformations; 4 cases were left coronary artery fistula and 3 cases were right coronary artery fistula. Two-dimensional ultrasound findings: in 7 cases, the involved coronary arteries were detected at the aortic root of the left ventricular outflow tract, showing different degrees of widening and expansion, with an internal diameter of 2.5-4.4 mm; In 2 cases, the left and right hearts were asymmetric and the left heart was small, while the other 5 cases were symmetrical. CDFI findings: abnormal tubular turbulent blood flow signals were detected in the aortic root or atrioventricular sulcus of 7 fetuses. Clinical outcome: 2 cases of isolated coronary artery fistula had good postoperative results; One case died at 37 weeks of gestation complicated with pulmonary artery stenosis, ventricular septal defect, and pericardial effusion, and the fetus; 4 cases were induced labor. Conclusion When using prenatal ultrasound to detect abnormal and obvious tubular blood flow signals in the aortic root or atrioventricular sulcus, it is necessary to be alert to the possibility of coronary artery fistula after tracing its origin, shape, and endpoint, which has important clinical value for the early treatment of the fetus after birth. |
