| 目的探讨超声心动图诊断胎儿右位主动脉弓(RAA)及其在预后评估中的应用价值.方法 回顾性分析经超声心动图诊断为胎儿RAA的25名单胎孕妇资料.7胎引产终止妊娠,对其中4胎进行胎儿尸体检查.对18胎继续妊娠者,于产后1个月内对患儿行超声心动图、MR或 CT检查,并临床随访半年,观察患儿有无反复发作的气管或食管受压症状.结果 19胎为RAA伴左位动脉导管、迷走左锁骨下动脉,4胎为RAA伴头臂动脉镜像分支(3胎伴右位动脉导管、1胎伴左位动脉导管),2胎为双主动脉弓.18胎为单纯性RAA,余7胎合并其他心内外畸形,且包括2胎染色体异常.4胎经尸体检查证实为RAA.18胎出生后经超声心动图、MR或CT检查证实为RAA患儿,且出生后半年内15例患儿无明显气管或食管受压症状,3例出现反复发作的慢性咳嗽、气喘,吞咽困难,经抗感染治疗后症状缓解.结论 超声心动图是诊断胎儿RAA的可靠方法;胎儿RAA的预后主要与是否并发其他心内外畸形或染色体异常有关. |

| Objective To explore the application value of echocardiographic diagnosis of fetal right aortic arch (RAA) and prognosis evaluation. Methods Datum of 25 pregnant women with RAA fetal confirmed by echocardiography were retrospectively analyzed. Seven fetuses were induced abortion, and 4 fetuses autopsy were carried out among them. For 18 fetuses continuously conceived, echocardiography, MR or spiral CT examination was performed during 1 months after the birth of the fetus, and clinically followed-up was last for six months in order to observe the fetus if had repeated episodes of trachea or esophagus press. Results Nineteen fetuses were RAA with left duct artefiosus and aberrant left subclavicular artery; 4 fetuses were RAA with brachiocephalic artery mirror branch (3 fetuses with right duct artefiosus, 1 fetuse with left duct artefiosus); 2 fetuses with double aortic arch. Eighteen fetuses were simple RAA; 7 fetuses combined with other intracardiac and exocardial malformations, including 2 fetuses of abnormal chromosome. Four fetuses were confirmed as RAA by autopsy. Eighteen fetuses were confirmed as RAA by echocardiography, MRI or CT, of which 15 cases had no obvious symptoms of tracheal or esophageal press symptom in the six months after birth; 3 cases had chronic cough, wheezing, dysphagia, whose symptoms were relieved after anti-inflammatory treatment. Conclusion Echocardiography is a reliable method for the diagnosis of RAA; the prognosis of RAA is mainly related to if combines other intracardiac and exocardial malformations or abnormal chromosome. |
