  2. Right-sided aortic arch - Wikipedia

    en.wikipedia.org/wiki/Right-sided_aortic_arch

    Right-sided aortic arch is a rare anatomical variant in which the aortic arch is on the right side rather than on the left. During normal embryonic development, the aortic arch is formed by the left fourth aortic arch and the left dorsal aorta. In people with a right-sided aortic arch, instead the right dorsal aorta persists and the distal left ...

  3. Aortic arches - Wikipedia

    en.wikipedia.org/wiki/Aortic_arches

    A double aortic arch; occurs with the development of an abnormal right aortic arch in addition to the left aortic arch, forming a vascular ring around the trachea and esophagus, which usually causes difficulty breathing and swallowing. Occasionally, the entire right dorsal aorta abnormally persists and the left dorsal aorta regresses in which ...

  4. Aortic arch - Wikipedia

    en.wikipedia.org/wiki/Aortic_arch

    The aortic arch is the connection between the ascending and descending aorta, and its central part is formed by the left 4th aortic arch during early development. [12] The ductus arteriosus connects to the lower part of the arch in foetal life. This allows blood from the right ventricle to mostly bypass the pulmonary vessels as they develop.

  5. Interrupted aortic arch - Wikipedia

    en.wikipedia.org/wiki/Interrupted_aortic_arch

    Type B: The aortic arch is interrupted between the left common carotid artery and the left subclavian artery. This is the most common form of the condition, and is the classification most often associated with DiGeorge syndrome. [2] [5] Type C: The aortic arch is interrupted between the innominate artery and the left common carotid artery. This ...

  6. Brachiocephalic artery - Wikipedia

    en.wikipedia.org/wiki/Brachiocephalic_artery

    The brachiocephalic artery, brachiocephalic trunk, or innominate artery is an artery of the mediastinum that supplies blood to the right arm, head, and neck. [1] [2] It is the first branch of the aortic arch. [3] Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery. [4]

  7. Double aortic arch - Wikipedia

    en.wikipedia.org/wiki/Double_aortic_arch

    Double aortic arch with left dominant arch: In this less common condition, as the name indicates, the left arch is the larger of the two aortic arches. The origins of the arm and head vessels are identical to the anatomy of double aortic arch with right dominant arch

  8. Vascular ring - Wikipedia

    en.wikipedia.org/wiki/Vascular_ring

    A less common ring is present with a right aortic arch instead of the usual left-sided aortic arch. This compresses the esophagus and trachea because of the persistence of a ductal ligament (from fetal circulation) that may connect between the aorta on the front and the left subclavian artery posteriorly going to the left arm. [citation needed]

    en.wikipedia.org/wiki/Aortic_arch_anomaly...

    Aortic arch anomaly - peculiar facies - intellectual disability is a rare, genetic, congenital developmental anomaly that is characterized by heart abnormalities, cranio-facial dysmorphia, and intellectual disabilities. No new cases have been reported since 1968.
