Figure 6

Patterns of the branching of the ascending aorta, left-sided and right-sided cervical aortic arches, and descending aorta in cases of unilateral aplasia of the common carotid artery (CCA). Note: Mullins et al., 1973 [78], cited by Haughton et al. [34]. Capital letter(s) in the small parenthesis indicate the vessel(s) originating from the ascending aorta, while these in the square parenthesis indicate the vessel originating from the descending aorta; other letters indicate the vessels branched from the arch of the aorta. A, aorta; C (C^∗), left (right) common carotid artery; S (S^∗), left (right) subclavian artery; E (E^∗), left (right) external carotid artery; I (I^∗), left (right) internal carotid artery; V (V^∗), left (right) vertebral artery; LIA, left innominate artery.
