Because of their anatomical localization, vertebral arteries were neglected in research for a long period of time. Vertebral arteries are responsible for about 30% of the brain blood supply. The aim of this study was to examine the vertebral artery's course in the first segment, and to define the anatomic variations and percentage of their appearance in the adult population using CT angiography...

We experienced a patient with a ruptured dissecting aneurysm of the vertebral artery who was treated by trapping of the lesion using Guglielmi detachable coils (GDCs) with micro-tornado® coils (MTCs). An 80-year-old male was transferred with a ruptured left vertebral artery dissecting aneurysm (VADA). The dissected portion of the vertebral artery was effectively trapped using GDCs and MTCs. The...

Jorge Mura, M.D. performed the microsurgery presented in this report on August 22, 2006 at the Institute of Neurosurgery Asenjo in Santiago, Chile. A highly vascularized tumor was present in the patient's only functional vertebral artery. Intraoperative neuromonitoring was conducted throughout the procedure. Following resection of the tumor and completion of the vertebral artery microanastomosi...

abstract background: in patients with cervical spondylosis, cord compression and impingement of cord vessels as well as the vertebral artery may be accompanied by vertigo. we evaluated improvement of vertigo in these patients after surgical and medical treatment. methods: in this prospective study we reviewed 16 patients with vertigo suspected of cervical spondylosis, admitted to our hospital b...

We present the case of a 57-year-old patient who was admitted to the hospital for preoperative cerebral angiography because of an intraspinal mass at the level of C1 and C2. Angiographic examination revealed an abnormal origin of the right vertebral artery, which normally originates from the right subclavian artery. Thus, the right vertebral artery was the last branch of the supraaortic vessels...

Vertebral artery dissection after neck manipulation has been well described. A case of bilateral vertebral artery dissection diagnosed with dynamic CT scanning of the neck is reported. The CT appearances and correlative angiographic and MR findings are presented.

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...

We recently read the interesting article by Albayram et al (1), which concisely explained the anomalies of the vertebral arteries. We would like to present another rare case of bilateral vertebral arteries originating from the aortic arch. We incidentally diagnosed this condition on the basis of findings on a chest CT scan obtained in a patient with trauma. Our trauma chest CT protocol uses 8 2...

Ruptured fusiform aneurysms of the vertebral artery involving posterior inferior cerebellar artery (PICA) origin are difficult to manage without sacrificing PICA. In this report, two very unusual cases are described which highlight different revascularization strategies that may be required. The first case initially appeared to be a small saccular PICA origin aneurysm, but detailed angiography ...

Vertebral artery aneurysms are a rare type of vasculopathy with significant risk rupture, ischemia, and potential neurological deficits. Their location in the cervical region presents surgical challenge open endovascular options alike lack consensus on best treatment option. We present an approach to vertebral aneurysm repair patient vascular Ehlers-Danlos syndrome (type IV). A 44-year-old male...
