Right sided aortic arch, V-shaped configuration

Sivasamy Manohar, MD. 


Case report

Following images show a case of the V-shaped right sided aortic arch diagnosed at 33 weeks. The reason of the V-shape configuration of the right-sided aortic arch is that the ductus arteriosus is right-sided.

Images 1, 2, 3, 4, 5, 6, and 7: 33 weeks; Images show transverse scan of fetal thorax at the level of 3-vessel trachea view with the V-shaped configuration of the pulmonary artery and aorta which runs on the right side of the trachea - right sided aortic arch. (lpa - left branch of the pulmonary artery; pa - pulmonary artery; a - aorta; s - superior vena cava; t - trachea, rvo - right ventricle).




Drawings 1, 2: Drawings represent relationships of the pulmonary artery (PA), aorta (Ao), superior vena cava (SVC), trachea (TR), descending aorta (dAo) at the level of the 3-vessel view of the heart. Drawing 1 represents normal relationships; Drawing 2 represents V-shape configuration of the pulmonary artery and right-sided aortic arch.
