1. Basilar artery tortuosity as a predictive factor for the efficacy of heparin adjuvant therapy in unilateral idiopathic sudden sensorineural hearing loss
Resumo Introdução A isquemia coclear é considerada uma das principais etiologias da perda auditiva neurossensorial súbita idiopática. Portanto, espera-se que as terapias anticoagulantes sejam benéficas em certos pacientes com esse diagnóstico. Objetivo Determinar quais pacientes com perda auditiva neurossensorial súbita idiopática se beneficiariam

2. Magnetic resonance angiography and transcranial Doppler ultrasound findings in patients with a clinical diagnosis of vertebrobasilar insufficiency
OBJECTIVE: To evaluate the findings of magnetic resonance angiography (MRA) and transcranial Doppler ultrasound (TCD) in patients with a clinical diagnosis of vertebrobasilar insufficiency (VBI). METHOD: From our outpatient neurotology clinic, we selected patients (using the criteria proposed by Grad and Baloh) with a clinical diagnosis of VBI. We excluded

3. Expression of Sphingosine-1-phosphate (S1P) on the cerebral vasospasm after subarachnoid hemorrhage in rabbits
PURPOSE: To demonstrate the relationship between of sphingosine-1-phosphate (S1P) expression and subarachnoid hemorrhage (SAH). METHODS: The basilar arteries from a "double-hemorrhage" rabbit model of SAH were used to investigate the relation between S1P expression and SAH. Various symptoms, including blood clots, basilar artery cross-sectional area, and S

4. Effect of cervical sympathetic block on cerebral vasospasm after subarachnoid hemorrhage in rabbits
PURPOSE: Cerebral vasospasm (CVS) is a major complication after subarachnoid hemorrhage (SAH) induced by the rupture of intracranial aneurysms. The aim of the present study was to investigate the effect and mechanism of cervical sympathetic block on cerebral vasospasm of the rabbits after SAH. METHODS: After successful modeling of cervical sympathetic block,

5. Influence of carotid siphon geometry and circle of Willis variants on the origin of carotid â posterior communicating aneurysms / InfluÃncia das variantes anatÃmicas do sifÃo carotÃdeo e do polÃgono de Willis na origem de aneurismas de carÃtida interna-artÃria comunicante posterior
IntroduÃÃo: Os aneurismas da artÃria carÃtida interna (ACI) no segmento comunicante posterior (AcomP) correspondem a 25% dos aneurismas intracranianos. Esses aneurismas sÃo mais freqÃentes em mulheres e apÃs a quarta dÃcada de vida. Por sua particular relaÃÃo anatÃmica com o sifÃo carotÃdeo e apresentar variabilidade relacionada à circulaÃÃo

6. Doença oclusiva da artéria basilar: aspectos clínicos e radiológicos / Basilar artery occlusive disease: clinical and radiological aspects
O objetivo deste estudo foi descrever as características demográficas, clínicas, radiológicas e o prognóstico da doença oclusiva da artéria basilar (DOAB), em uma população multiétnica. Foram estudados 40 indivíduos com infartos no território da artéria basilar (AB) confirmados por ressonância magnética, que sobreviveram após 30 dias à fase

7. Modificação da craniotomia subtemporal: Contribuição ao acesso cirúrgico à bifurcação da artéria basilar / Modification of subtemporal craniotomy. Contribution to the surgical access to the basilar artery bifurcation
Esta pesquisa analisa experimentalmente as diferenças de comportamento entre a versão clássica e a modificada da craniotomia subtemporal quanto à retração do lobo temporal. A retração é medida pelo ângulo de visão, através do microscópio, obtido ao mirar-se estruturas previamente estabelecidas. Estudou-se a correlação estatística entre a retr

8. Injury of the basilar artery associated with closed head trauma1
The neuropathological findings at necropsy are described in three cases of basilar artery injuries and their consequences after head trauma and the mechanism of injuries is discussed. The first case was that of massive pontine infarct due to an occlusion of the basilar artery trapped in the fracture of the clivus, 13 days before death. The second case, also

9. Bilateral occlusion of basilar artery branches.
In a case in which the patient became totally paralysed except for blinking and vertical eye movements, microscopic serial sections of the pons showed bilateral infarcts which were due to occlusion of two small basilar branch arteries, one on each side. One basilar branch was occluded by an atheroma lying at its junction with the basilar artery and the other

10. Basilar artery dissection.
Dissection of the basilar artery caused sudden coma and death in a 40-year-old man. Atypical clinical features were explained at necropsy. A ventral dissection of the artery within its outer layers resulted in destruction of the pontine tegmentum with sparing of the basis pontis. An unsuspected defect in the internal elastic lamina in the left internal carot

11. Ionic mechanisms in spontaneous vasomotion of the rat basilar artery in vivo.
1. The goal of this study was to examine ionic mechanisms that modulate spontaneous rhythmic changes in vascular calibre or 'vasomotion' in the basilar artery in vivo. 2. Diameter of the basilar artery was measured through a craniotomy in anaesthetized rats under control conditions and during topical application of antagonists or alteration in the ionic comp

12. Basilar artery ectasia: an unusual cause of trigeminal neuralgia.
Basilar artery ectasia may be associated with trigeminal neuralgia as a consequence of trigeminal nerve compression by the aberrant artery. The case histories are presented of four patients, investigation of whom demonstrated the presence of an ectatic basilar artery thought to be the cause of facial pain. The value of intravenous digital subtraction angiogr
