“…As outlined in literature, one individual may have an absence of their right CCA with a common origin of the innominate artery and left CCA. 1 Another variant involves a bilateral absence of the carotid arteries, although there have only been 2 reported cases on bilateral absence of the carotid arteries in literature. 2 Regardless of the variations associated with an absent CCA, there are fewer than 50 reports of individuals with a congenital absence of one or both of their common carotid arteries.…”

This case report provides a review of the occurrence, variations, signs/symptoms, and gender/side preferences of an absent common carotid artery (CCA) anatomical variant. Normal embryology of the carotid arteries and associated structures are also discussed. The relationship between absent common carotid bifurcations and the risk for plaque development is also considered but is limited due to the lack of empirical evidence. This report also outlines and demonstrates an absent right CCA with direct, separate origins of the right external carotid artery and right internal carotid artery from the right subclavian artery. An absent CCA is a rare vascular anomaly with multiple variations. There are typically no associated signs/symptoms, and there are no gender or side preferences.

Background Anatomical variations of origin of the internal carotid artery (ICA) are very uncommon and may pose a diagnostic and therapeutic challenge. Objective We report a case of direct origin of the right ICA from the innominate artery (aplasia of common carotid artery) and a case of duplication of right ICA in healthy patients who performed duplex ultrasound (DUS) for primary cardiovascular prevention screening. Methods In both cases, the ultrasound scan was performed both in a transverse plane and on the longitudinal axis, and in one of the two cases, a computed tomography angiography was performed to confirm the diagnosis. A review of the current literature about anatomical variations of origin of carotid arteries was also performed. Results The most frequent congenital anomaly is represented by the aplasia of the CCA, followed by the agenesis and by the duplication of the ICA. In most cases, the anomaly is discovered occasionally and symptoms are aspecific. Diagnosis is usually confirmed through a multimodality imaging approach, including DUS of extracranial carotid arteries, magnetic resonance imaging (MRI), and computed tomographic angiography. In most cases, treatment was conservative, with pharmacological therapy aimed at the symptoms. Conclusion The recognition of such variations is mandatory, particularly when the patient needs a surgical treatment that may involve the vessel with the anatomical variations.
