background: the goal of this study was to determine the reliability of tcd in evaluation of vertebrobasilar arteries in comparison with brain mra in patients suffering from acute vertebrobasilar stroke. methods: samples were patients with definite clinical diagnosis of vertebrobasilar stroke. for all patients brain mri, mra and tcd were performed during the first 48 hours of admission. basilar ...

abstract symptomatic basilar artery stenosis has a poor prognosis. surgical bypasses are technically demanding and of no proven benefit. a new generation of intravascular stents that are flexible enough to navigate the tortuosities of the vertebral artery may provide a new therapeutic approach. our two cases, 57 and 52 year-old men experienced a vertebrobasilar ischemia with repeated vertigo an...

Because the blood supply to the inner ear originates from the vertebrobasilar system, vertebrobasilar ischemic stroke can present with vertigo and hearing loss due to infarction of the inner ear (i.e., labyrinthine infarction). Sometimes vertigo and hearing loss are warning symptoms of impending vertebrobasilar ischemic stroke (mainly in the anterior inferior cerebellar artery territory). In th...

Background: vertigo may be a warning sign of impending vertebrobasilar stroke. Objective: To investigate the role of brain stem auditory evoked potential (BAEP), electronystagmography (ENG) studies and results of transcranial Doppler (TCD) in patients with vertigo of vertebrobasilar origin and patients with vertigo of non-vertebrobasilar origin. Methods: Twenty five patients with vertigo aged 4...

BACKGROUND AND PURPOSE Incapacitating vertebrobasilar insufficiency is generally associated with bilateral vertebral artery disease, whereas unilateral vertebral artery stenosis usually is clinically silent. Regional brain perfusion has not been part of the routine evaluation of patients with vertebrobasilar insufficiency. This report describes two patients who had isolated unilateral vertebral...

Background: Clinical information about stroke in the vertebrobasilar territory has lagged behind that for anterior circulation syndrome. This is the first report from posterior circulation syndrome registry in Iran. Methods: Consecutive patients with brain infarction in vertebrobasilar territory admitted to Ghaem hospital, Mashhad were enrolled in a prospective study during 2006-2007. Diagnosis...

PURPOSE To characterize the clinical, MR, MR angiographic, and conventional angiographic findings in vertebrobasilar disease in children. METHODS Eight children with posterior circulation ischemia and infarction had conventional spin-echo MR and MR angiography of the head and neck. Six patients had conventional angiography. RESULTS Six patients had alteration of vertebral or basilar artery ...

Spontaneous intracranial vertebrobasilar dissection can manifest with various clinical symptoms, including subarachnoid hemorrhage or ischemic symptoms from impaired posterior circulation. A 29-year-old woman came to our emergency department with a sudden onset of left sided mild motor weakness and headache. Initial magnetic resonance imaging (MRI) showed mild luminal irregularities in the vert...

The majority of patients with acute sensorineural hearing loss have peripheral vestibulocochlear disorders such as sudden deafness or Meniere’s disease. However, ischemia of the vertebrobasilar artery can also cause vestibulocochlear symptoms such as sensorineural hearing loss and vertigo [1]. The vertebrobasilar artery supplies the inner ear, brainstem, and cerebellum. Ischemia of the vertebro...
