Abstract
AbstractFetal double aortic arch (DAA) is a rare congenital arch anomaly characterized by the presence of two aortic arches instead of the normal single arch. DAA is an uncommon finding during routine fetal echocardiography.Prenatal ultrasound detection of fetal DAA is crucial for early identification and appropriate management of affected fetuses. Despite the challenges and limitations, advancements in imaging technology and expertise have improved diagnostic accuracy.Four-dimensional (4D) ultrasound provides a volumetric representation of the fetal structures. It allows for better visualization and assessment of complex anatomical abnormalities, including DAA. With 4D imaging, the sonographer can manipulate the image, rotate it, and view it from different angles, aiding in the identification of the double arch anomalyThis is a case of double aortic arch diagnosed with the spatiotemporal image correlation (STIC) technique of 4D ultrasound using color Doppler.
