BACKGROUND Tortuous blood vessels are commonly seen in the cerebral arteries. The association between vertebrobasilar artery tortuosity and vascular vertigo remains obscure. CASE PRESENTATION We describe two patients with vascular vertigo who had bilateral curving and spiral looping in multiple segments of the vertebral arteries and also exhibited basilar artery tortuosity. Both patients had ...

Neurological manifestation may complicate Takayasu arteritis (TA). A 23-year-old girl with sudden onset of vision loss was admitted to hospital. Her brain MRI showed abnormal T2-signal hyperintensity and visual evoked potential revealed prolonged P100 latency. Consequently, optic neuritis was diagnosed. A review on history of dizziness, falling, and weak pulses of upper extremities led to more ...

BACKGROUND AND PURPOSE In some patients with stenosis of an intracranial artery, navigating the balloon or stent-delivery system is difficult of tortuous anatomy of the aortic arch, carotid arteries, or vertebral arteries Our purpose was to describe techniques of intracranial stent placement that help in navigating the stent-delivery system in tortuous vessels. METHODS Between May 1998 and Ju...

Vertebral artery injury (VAI) during posterior cervical spine surgery is a rare but potentially disastrous complication. Placement of screws in the posterior cervical spine is the most common cause of VAI; however, aberrant anatomy may be a potential cause of inadvertent injury in an otherwise routine exposure of the posterior cervical spine. In this article, Molinari et al described two cases ...

Bilateral carotid and vertebral rete mirabile (CVRM) is a very rare condition. We report a new case of CVRM initially detected by magnetic resonance imaging (MRI) of the cervical spine. MRI demonstrated tortuous vascular signal voids limited to the anterior cerebrospinal fluid space mimicking spinal dural arteriovenous fistula. A diagnosis of CVRM was confirmed on the basis of angiographic find...

BACKGROUND AND PURPOSE Antecedent balloon test occlusion is often performed prior to vertebral artery sacrifice, but there is limited data to suggest this adds a significant clinical benefit, especially in the setting of trauma. Furthermore, balloon test occlusion can be time-consuming, add to the technical complexity of the procedure, and increase the overall cost of treatment. The purpose of ...

Current work aims to investigate the brain blood supply of local rabbit, where 14 rabbits both sexes were used with weights ranging from 3-3.5 kg. This study revealed that rabbit's is supplied by vertebral and internal carotid artery (ICA). The union arteries creates basilar runs on ventral surface pons medulla oblongata, forming at its end posterior communicating (PCA), as well path which foll...

During color Doppler examination of a 41-year-old man who presented with vertigo, a right vertebral artery could not be found. Both MR angiography and digital subtraction angiography revealed a large anastomotic vessel between the right internal carotid and vertebral artery. It was thought to be type I proatlantal artery. Furthermore, the external carotid arteries were bilaterally absent. Altho...

Seven cases of aneurysm of the vertebral and basilar arteries, in which the clinical features suggested a diagnosis of posterior fossa tumour, are presented. Their clinical manifestations and the difficulties of diagnosis are discussed. These lesions may mimic cerebellopontine angle tumours or brain-stem gliomas, or, less commonly, the picture is one of a compressive lesion at the foramen magnu...

Dear Sir, Spinal cord infarction is much less frequent than cerebral infarction, accounting for only 1% of all strokes and, furthermore, posterior spinal cord infarction is particularly rare [1–3] . Etiologies of spinal cord infarction are heterogeneous such as vertebral dissection, hypotension, atherosclerosis of vertebral arteries, cocaine mis use, fibrocartilaginous embolization, aortic aneu...
