“…[4] But it is also reported that the altered hemodynamics of the anomalous origin may predispose a patient to certain cerebrovascular pathologies like aneurysm and dissection. [56789] We report here an incidental observation of bilateral duplication of the V-1 segment of the vertebral artery and to the best of our knowledge this is the third such case to be reported.…”

Bilateral duplicated origin of V-1 segment of vertebral arteries is an extremely rare vascular variant and only two such cases have been reported so far. Presence of this vascular abnormality was observed incidentally in a 36-year-old male patient, with a complaint of dizziness, evaluated by multidetector row computed tomography (CT) angiography. Two limbs of the right vertebral artery arose from the right subclavian artery and fused to form a single vessel at the interval between fourth and fifth cervical vertebrae, which entered the foramen transversarium of fourth cervical vertebra. On the left side, the medial limb originated directly from the arch of aorta and the lateral limb from the left subclavian artery, and both united at the interval between fifth and sixth cervical vertebrae to form a single vessel which entered the foramen transversarium of fifth cervical vertebra. No other cerebrovascular pathology like aneurysm, fenestration, dissection, and stenosis was detected, which could be correlated with the symptoms of the patient. This rare congenital vascular anomaly has diagnostic and therapeutic implications in any intervention involving the vertebral artery.

“…One of the rarest anomalies is the duplication of the extracranial segments of vertebral arteries, which is usually an incidental finding in an autopsy series, angiographic studies or, more recently, MR and CT angiography and color Doppler studies (Harnier et al 2008; Ionete and Omojola 2006; Kendi and Brace 2009; Mahmutyazicioglu et al 1998). …”

Duplication of the left vertebral artery in a patient with dissection of the right internal carotid artery and Ehlers–Danlos syndrome: case report and review of the literature

et al. 2012

Duplication of the left vertebral artery was observed in a 43-year-old Caucasian male with dissection of the right internal carotid artery during multidetector 64-row computer tomography and Doppler ultrasonography B-flow mode. Both duplicated segments arose from the left subclavian artery and united at levels C5–C6 to form a single vessel. The presented case describes precisely the origin and diameter of both vertebral arteries. Additionally, after all procedures associated with diagnosis and treatment of the patient, Ehlers–Danlos syndrome type IV was diagnosed. The lumen of the duplicated vertebral artery was smaller than normal; it can be concluded that this variant has clinical implications and should be taken into consideration when vertebral arteries need catheterization.

Duplication of the vertebral artery (VA) is rare but clinically significant. This variant shows a dual origin of VA with fusion at variable levels in the neck. It can be misdiagnosed as a dissection of the VA, arterial hypoplasia, or narrowing on selective catheter angiography. Thorough knowledge of this variation before an endovascular procedure is helpful in preventing unintentional diagnostic or therapeutic challenges. We report a case of a 52-year-old female patient with left duplicated VA, which was incidentally detected by magnetic resonance angiography (MRA) and contrast-enhanced computed tomography angiography (CTA). We have also reviewed the literature and discussed the embryological development of duplicated VA. This report can be helpful in identifying unexpected vascular variations on CTA or MRA and differentiate this anatomical variation from other pathologic conditions in clinical practice such as dissection, arterial hypoplasia, or arterial narrowing.
