Right-sided aortic arch is a rare vascular pathology. Although its progress is asymptomatic, if there is compression on trachea or esophagus, chronic cough, dyspnea or dysphagia may occur. During postnatal period, its diagnosis is frequently established during the differential diagnosis of obstructive pulmonary diseases. Fetal cardiac screening is one of the most significant parts of fetal anomaly screening. Fetal heart should be evaluated in terms of the appearance of four chambers, the appearance of five chambers and the appearance three vein trachea. Thirty-one-year-old G3P1A1 patient who was followed up at an external center referred to our clinic at 24 weeks of gestation for fetal anatomic screening. Her combined test screening was normal in the first trimester. In the sonographic anatomic screening performed, fetal anatomy was evaluated as normal and her biometric measurements were compatible with the week of gestation. In the fetal cardiac examination, 4-chamber and 5-chamber plans and major vessel outlets were seen as normal. It was seen in the three vein trachea that aorta was located on the right side of the trachea. No additional anomaly associated with right-sided aortic arch was observed in the echocardiography. It was planned to perform fetal karyotyping and DiGeorge syndrome screening to the patient. Karyotype result done by cordocentesis was normal and 22q11 microdeletion was not found. The perinatal follow-up of the patient has been maintained at our clinic. In this study, we presented the case which had no fetal anomaly other than right-sided aortic arch in the fetal anomaly ultrasound screening. In such cases, fetal karyotyping and second trimester detailed anatomic screening should be done. Since dyspnea, chronic cough and dysphagia may arise in the newborn, the antenatal diagnosis of right-sided aortic arch is important.
