BACKGROUND
The purpose of our experiment was to determine whether laser stimulation can improve microcirculation in the posterior regions of the brain in patients with vertebrobasilar insufficiency (VBI).
METHODS
We studied 25 patients (20 female, 5 male, mean age 64) diagnosed with chronic VBI. All
METHODS
Case report.
OBJECTIVE
To present a rare case of vertebrobasilar insufficiency (VBI) syndrome secondary to the C6 level isthmic spondylolisthesis.
BACKGROUND
VBI associated with voluntary head movements is known as the bow hunter syndrome. It may manifest in temporary symptoms of dizziness,
To investigate the association between the perfusion magnetic resonance imaging (MRI) and vertebrobasilar dolichoectasia (VBD) in vertigo patients and at least one vascular risk factor.We studied 289 patients with vertigo (spinning, swaying, nausea, Vertebrobasilar insufficiency is characterized by impaired blood flow within the posterior circulation, producing symptoms of vertigo, nausea, vomiting, visual disturbances, and syncope. Given these nonspecific symptoms, the diagnosis of vertebrobasilar ischemia may be difficult to distinguish from
Fenestration of basilar artery is an uncommon vascular anomaly that is usually an incidental product on autopsy or angiography. None of the cases in the literature had clinical symptoms associated with this anomaly except for subarachnoid hemorrhage when accompanied with saccular aneurysm. We report
BACKGROUND
A carefully designed intracranial stent-assisted angioplasty (SAA) is presented here that may prevent subsequent branch artery occlusion.
UNASSIGNED
A 72-year-old man with a 3-month history of progressive and intermittent vertigo without any obvious trigger, accompanied by
Bow hunter's syndrome (BHS), or positional vertebrobasilar insufficiency, is a rare disorder characterized by positional stenosis or occlusion of the dominant vertebral artery (VA) with concordant signs and symptoms of brainstem ischemia. Many etiologies have been described, with the most common
BACKGROUND
This article describes delayed endovascular revascularization in a patient with clinical and radiographic evidence of posterior circulation hemodynamic failure in the setting of intracranial occlusive lesions.
METHODS
A 48-year-old man presented with a 6-week history of progressive
OBJECTIVE
Monitoring of the basilar artery (BA) is difficult and has been sparsely performed. The aim of this study was to present physiological data of functional transcranial Doppler sonography (TCD) of the BA during caloric vestibular stimulation in healthy volunteers.
METHODS
TCD of the BA was
BACKGROUND
Vertebrobasilar dolichoectasia (VBD) is a rare vasculopathy. The etiology of this disease is unknown. Transient ischemic attacks (TIAs) of vertebrobasilar system refer to a transient (< 24 hours) lowering of blood flow in the posterior circulation of the brain. We present a case of
A 29-year-old, 39-week-pregnant female who had headache and nausea was admitted to our hospital. She bore a baby son by natural delivery after several hours. After labor, her headache was continuous. Brain CT scan demonstrated intracerebral and intraventricular hemorrhage. After conservative
A 76-year-old female presented with vertebrobasilar insufficiency due to a severe stenosis of the right primitive hypoglossal artery (an unusual carotid-basilar anastomosis) manifesting as recurrent transient ischemic attacks (TIA) associated with quadriparesis and cerebellar ataxia with vertigo,
Hyperperfusion syndrome is a well-documented clinical complication after endarterectomy and carotid stenting. However, little is known about this complication immediately after vertebral artery stenting. A 51-year-old woman who had repeated episodes of dizziness, nausea, and vomiting was diagnosed
BACKGROUND
Bow hunter syndrome describes a mechanical compression of the vertebral artery on head rotation leading to reversible symptomatic vertebrobasilar insufficiency. Patients are commonly presenting with syncope, vertigo, dizziness, and visual disturbances. These symptoms usually resolve when
Bow hunter's syndrome is a condition in which vertebrobasilar insufficiency is resultant from head rotation, clinically manifested by presyncopal sensation, syncope, dizziness, and nausea. It is usually diagnosed clinically, with supporting vascular imaging demonstrating an occluded or at the very
