Aberrant origin of right vertebral artery from the arch of aorta.

We present a rare case of an aberrant right vertebral artery originating from the arch of aorta distal to the origin of the left subclavian artery. The incidence of this particular variant of aberrant origin of the right vertebral artery is extremely uncommon with only seventeen cases reported in literature to date. This case was incidentally detected on a staging positron emission tomography-computerized tomography (PET-CT) scan for lung cancer. We review the incidence, embryological mechanism, and clinical importance of this aberrant course of the right vertebral artery.

A Study Of Variations In The Origin Of Vertebral Artery And Its Clinical Significance

Objectives: An understanding of anatomy is essential to surgeons and knowledge of variations is of practical importance. The anatomic and morphologic variations of great vessels are significant for diagnostic and surgical procedures in the neck and thorax region. Vertebral artery is a branch of subclavian artery, generally arising from the first part of subclavian artery on both the sides. Multiple variations in the origin of vertebral artery have been reported in the literature, most common being directly from the arch of aorta, as a branch of thyrocervical trunk, as a branch of common carotid or external carotid artery. Material and methods: Study was carried out among 30 formalin fixed cadavers procured from Dr. D.Y.Patil Medical College, to note down the variations in the origin of vertebral artery. Results: Origin of right vertebral artery was normal in all the cases while the left vertebral artery showed varied origin. Conclusions: Anomalous vertebral artery origins may predisposes an individual to cerebrovascular disorders.

Right subclavian steal syndrome in a patient with aberrant right subclavian artery, common carotid trunk and hypoplastic left vertebral artery

Introduction: Subclavian steal syndrome refers to the reversal of vertebral blood flow in the setting of proximal subclavian or innominate artery severe stenosis or occlusion resulting in the symptoms of vertebrobasilar insufficiency related to exercise of the upper extremities. It is more common on the left side. Case report: We reported a case of subclavian steal syndrome on the right side in a patient with aberrant right subclavian artery (ARSCA), hypoplastic left vertebral artery and common carotid trunk (CCT) branching in to the left and right common carotid arteries. Conclusion: Till now, combination of ARSCA, CCT and left vertebral artery hypoplasia in the same person has not been reported and this combination causes ischemia in large area of brain if the patient develops hemodynamically significant stenosis or occlusion in both CCT and ARSCA proximal to the origin of right vertebral artery.

Anomalous Origins of Bilateral Vertebral Arteries in a Child with down Syndrome and Moyamoya Disease

Variations in vertebral artery origin and course are well-described in the literature. The origin of right vertebral artery from the right common carotid artery is an extremely rare variant. We describe a unique case of a child with Down syndrome with variant origins of bilateral vertebral artery, an aberrant right subclavian artery and concomitant Moyamoya disease of intracranial circulation. The presence of variations of the origin and course of craniocervical arteries might have profound implications in angiographic and surgical procedures and hence it is of great importance to be aware of such a possibility.

Successful Recanalization of a Chronic in-Stent Occlusion at the Vertebral Artery Ostium

In-stent restenosis or occlusion has been frequently reported as a complication after angioplasty and stenting in vertebral arteries. Reopening chronic in-stent occlusion in cervical arteries with endovascular techniques has not been reported. Here we describe a case with stent implantation in the origin of right vertebral artery. The stent was occluded one year after the procedure. The patient demonstrated concurrent ischemic symptoms which were relieved after the in-stent occlusion being recanalized successfully with re-angioplasty.

Duplicated origin of right vertebral artery with rudimentary and accessory left vertebral arteries

We observed a rare cerebrovascular anomaly in a patient with brain-stem infarction. Two right vertebral arteries arose from the subclavian artery and communicated directly with each other under the transverse foramen of the fourth cervical vertebra. The left vertebral artery consisted of a rudimentary artery that arose from the left subclavian artery, ran through the transverse foramen of the sixth cervical vertebra and then tapered down to disappear at the fourth/fifth cervical vertebrae, plus a second, accessory artery that arose from a branch of the left thyrocervical trunk, ran through the transverse foramen of the fifth cervical vertebra and tapered off to disappear at the first/second cervical vertebrae.
