Anomaly of the Embryonic Development of the Aortic Arch

Herein, an anomaly of the embryonic development of the aortic arch, classified as one of the forms of a vascular ring, in which the vessels encircle and compress the trachea and esophagus is presented. Consequently, the child may experience recurrent lower respiratory tract infections accompanied by inspiratory stridor. Additionally, the child may exhibit reduced exercise tolerance. Esophageal obstruction typically manifests in infants and toddlers during the transition to solid food, when they may reject solid bites or regurgitate undigested contents. There is a right-sided aortic arch with an aberrant origin of the left subclavian artery from Kommerell's diverticulum. The complete aortic ring is formed by the ligamentum arteriosum, which connects Kommerell's diverticulum to the left pulmonary artery.

The model is composed of five .STL files corresponding to each anatomical structure (aorta, arteria pulmonalis, esophagus, ligamentu, trachea), which, when combined, provide a general anatomical structure, which you can see at the image. The models are small, up to 9 MB for aorta. Printing each structure is suitable even for smaller 3D printers. We do recommend to print each structure by different color and then glue it together to make a nice looking model.
