Non-bifurcating cervical carotid artery

Carotid Artery Stenting for Atherosclerotic Stenosis Associated With Non-bifurcating Cervical Carotid Artery

“…Multiple anomalies of the carotid artery are known, but non-bifurcating cervical carotid artery is rarely described, with only 5 cases of non-bifurcating cervical carotid artery, 7,14,15,19,22) and 6 similar cases with various terminologies. 3,6,8,16,17,20) Two hypotheses have been described for the development of these anomalies, agenesis of the ECA trunk, 3,8) and segmental agenesis of the ICA.…”

“…3,6,8,16,17,20) Two hypotheses have been described for the development of these anomalies, agenesis of the ECA trunk, 3,8) and segmental agenesis of the ICA. 7,14,17,19) Non-bifurcating cervical carotid artery might be caused by absence of regression of the proximal hyoid artery with failure of transfer of its distal branches. 8) Embryologically, the cervical carotid artery develops from the ventral aorta, dorsal aorta, and aortic arches ( Fig.…”

“…7,14,15,19,22) We describe here the case of a patient successfully treated with carotid artery stenting (CAS) for atherosclerotic stenosis associated with non-bifurcating cervical carotid artery and discuss the presumed embryological development of this anomaly.…”

Nonbifurcating Cervical Carotid Artery Diagnosed by MR Angiography

“…Only 11 cases have been reported in the English language literature. [1][2][3][4][5][6][7][8][9] This anomaly is also called "unilateral" 2 or "congenital absence of the ECA." 6 We believe that this is the first report of this anomaly studied with MRA.…”

Asymptomatic Non-Bifurcating Carotid Artery

“…given that the diameter of the non-bifurcating artery is more similar to that of the contralateral ECA as opposed to the ICA. Our review of the literature identified ten case reports [8][9][10][11][12][13][14][15][16][17] and one small retrospective study 18 documenting this vascular anomaly. It is unclear when the first description of a similar anomaly dates back to, but it appears that in 1821, Allan Barns described a case of single carotid vessel without any appreciable bifurcation on cadaveric dissection, and with the vessels that typically arise from the ECA originating from the ICA 19 .…”
