Bilateral Absence of the Common Carotid Arteries with Separate Origins of the Internal and External Carotid Arteries Detected by CT Angiography: Case Report

Abstract

We report a rare case of bilateral absence of the CCAs with separate origins of the ICAs and ECAs, detected by CTA.

“…However, there are even fewer angiographically proven cases of this anomaly. Supsupin7 first demonstrated bilateral absence of the common carotid artery on CT angiogram. There were two reported cases of this anomaly with symptomatic stenosis, and in three cases this was associated with intracranial aneurysm 8.…”

Congenital Aplasia of the Common Carotid Artery: A Comprehensive Review

“…Aplasia of Bilateral CCA. Supsupin et al [38] sketched the separated origin of the both-sides ECA and ICA as the consequence of an obliteration of the third PAA followed by the persistence of the DC on the both sides, while Shuford et al [39] sketched the interruption of the le embryonic arch between the le SA and the carotid arteries in a hypothetical double aortic arch with an independent origin of the carotid arteries ( Figure 4).…”

“…e patterns of the NAA branching were di erent in these cases; the number of these branches ranged from two [7,[52][53][54] to ve [18,[55][56][57]. Hovewer, the NAA with four branches was a more common nding associated with the le CCA aplasia [1,10,11,16,42,43,49,51,[58][59][60][61][62][63], than with the right [13,18,26] or bilateral CCA aplasia [38,64,65]; a pattern of the NAA with three branches was more common in the cases of the right CCA aplasia [5, 14, 15, 17-25, 27-29, 66], than in the cases of the le [67,68] or bilateral CCA aplasia [69] (Figure 5).…”

“…ere was one case of the bilateral origin of the ECA and ICA from the DAA [40], as cited [6], while there were two Uchino et al [46], Haughton and Rosenbaum's [47] case cited by Bryan [43], and one Weinberg's [48] case. ese cases were found in the patients or cadavers of both gender (37 of female, 24 of male and 26 of unknown sex), between the age of a newborn and 77 ( NAA: B+I+V+S [65] NAA: B+E+IV+S [38] NAA: B+E +E+I+S [55] F 5: Patterns of the branching of the normal aortic arch in cases of uni-and bilateral aplasia of the common carotid artery (CCA).
