A case of aberrant bilateral vertebral arteries orgin presenting with right VA dissection
Authors
Abstract:
Background: Knowledge of variations in the origin of vertebral artery (VA) is indispensable to vascular surgeons. Aberrant origin of vertebral artery on either side is an uncommon finding. There are unilateral and bilateral variability in VA origin. Case presentation: We present a case of vertebral artery dissection who was found to have bilateral VAs aberrant origin. The right VA took origin from the right common carotid artery (CCA) which is a completely a rare finding, and the left VA originated from the arch of aorta. Conclusion: Unlike most similar reported cases, the VA diameter at origin was larger on the left than on the right side. The possible embryological mechanism is discussed.

A 5-year-old boy was evaluated for a left retrotympanic mass found at otoscopy. Subsequent petrous bone CT and MR angiographic examinations demonstrated bilateral aberrant internal carotid, bilateral stapedial artery persistence, and bilateral duplicated internal carotid arteries. Imaging findings and their clinical relevance are discussed. A second case of unilateral aberrant internal carotid ...

The persistent proatlantal artery is a well-described communication between the carotid and vertebrobasilar system. However, persistence of bilateral proatlantal arteries is exceptionally rare. Although usually noted as an incidental finding, the presence of a proatlantal artery, particularly when bilateral, may result in unusual symptoms or may have implications for therapy. We report a case o...

A case of bilateral anomalous origins of the vertebral arteries (VAs) is reported. Both VAs arose directly from the aortic arch between the left common carotid artery and the left subclavian artery. The possible embryologic mechanism and clinical importance of this previously unreported variant are reviewed.

Vertebral artery dissection usually presents with neck, occipital, or shoulder pain along with symptoms of ischaemic stroke in the posterior circulation. Isolated pain, asymptomatic cases, or misleading presentation mimicking migraine or myocardial infarction have been seldom reported. Peripheral upper limb deficit or isolated radicular neuralgia due to vertebral artery dissection have also bee...

Spinal manifestations of vertebral artery dissection (VAD) are rare events and are typically symptomatic with neck pain and ischemic brain injury. We report a patient presenting with unusual peripheral paresis of the right upper limb due to an intramural hematoma of the right vertebral artery with local compression of C5 and C6 as the cause of cervical radiculopathy. These symptoms completely r...
