Unusual aortic arch variation: Distal origin of common carotid arteries

CT Angiographic Study of Anatomical Variations of Aortic Arch Branches in Libyan Patients

“…It has been found at autopsy from individuals of Japanese descent born in Hawaii, that out of 193 individuals, 182 (94.3%) show a typical artery branching pattern trees [10] which is in line with this study. Also, in agreement with our study, Lale et al [6] reported that in 881 of studied cases, the classical variation of the aortic arch was observed in 87.4% (770) of the total number of cases.…”

Morphologic features of the aortic arch and its branches in the adult Chinese population

“…4,6 An autopsy study of 193 Japanese Americans identified only two specimens (1.03%) as having the type B pattern. 15 However, a recent study from Japan reported a type B incidence of 11.5%, which is similar to our study (10.3%). 16 Race appears to play an important role in variations of arch branches.…”

Origin of the Left Common Carotid Artery From the Brachiocephalic Artery

“…A study done by Nelson aortic arch, a common trunk uniting the brachiocephalic and left common carotid arteries and a left subclavian artery.In this type, the left common carotid artery arises from a common trunk with the brachiocephalic trunk [5]. The variation observed in this case report is similar to what Sora et al 2002, described in which the brachiocephalic artery and the left common carotid arose from a common trunk from the arch of the aorta except that in our case the left common carotid artery arose from the brachiocephalic artery [1].…”
