Detection of Anomalous Cervical Internal Carotid Artery Branches by Colour Duplex Ultrasound

Abstract

Branches from the ICA exist and can be characterised with CDU. Prevalence in a tertiary hospital referral cohort is 4%. Given their potential clinical implications, standard carotid imaging protocols should consider routine assessment and reporting of ICA branches.

Imaging Challenges in the Diagnosis of Anatomical Variations of the Supra-Aortic Vessels: A Case Report and Review of Literature

“…Aberrant variations in the carotid artery systems are uncommon findings and include hypo/aplasia of the internal carotid artery, anomalous cervical internal carotid artery branches, etc. [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ].…”

“…Additionally, another congenital anomaly is the origin of the vertebral artery directly from the aortic arch, known as the “Adachi TYPE C” variation. These anomalies rarely coexist, due to embryological defects of development in the primitive aortic arch vessels [ 2 ]. Although all these congenital anomalies of the cervical vessels may remain asymptomatic, they are associated with important potential clinical implications.…”
