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 ...
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 ...
The arches are numbered from 1 to 6, with 1 being the arch closest to the head of the embryo, and the fifth arch only existing transiently. [10]: 318–323 Arches 4 and 6 produce the laryngeal cartilages. The nerve of the sixth arch becomes the recurrent laryngeal nerve. The nerve of the fourth arch gives rise to the superior laryngeal nerve.
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.
The aortic arch, arch of the aorta, or transverse aortic arch (English: / eɪ ˈ ɔːr t ɪ k / [1] [2]) is the part of the aorta between the ascending and descending aorta. The arch travels backward, so that it ultimately runs to the left of the trachea .
Double aortic arch is a subtype of complete vascular ring. There are three types of double aortic arch: Right dominant arch (about 70% of surgical cases) Balanced or codominant (about 5%): both arches are of equal size; Left dominant (about 25%) Double aortic arch with right dominant arch: Normally there is only
The anterior communicating artery connects the two anterior cerebral arteries and could be said to arise from either the left or right side. All arteries involved give off cortical and central branches. The central branches supply the interior of the circle of Willis, more specifically, the Interpeduncular fossa.
Due to its low frequency of occurrence, more common causes of hoarseness should be considered when suspecting left recurrent laryngeal nerve palsy (LRLN).. When considering cardiovocal syndrome, the most common historical cause is a dilated left atrium due to mitral stenosis, but other causes, including pulmonary hypertension, [2] thoracic aortic aneurysms, an enlarged pulmonary artery [3] and ...
