1] The duplicated VA is a significant predisposing factor of vertebrobasilar
cervical artery dissection due to local histological defect (hypoplasia) or significant hemodynamic alteration.
A 2008 study showed an association between vertebrobasilar
stroke and chiropractic visits within one month of the vascular event.
sup], Digital subtraction angiography (DSA) can be used to identify potential vascular injury and trauma-related pseudoaneurysm of the ICA and vertebrobasilar
Conditions that affect the brain vessels in childhood including vertebrobasilar
artery failure, subclavian steal syndrome, migraine, Moyamoya disease, and Takayasu disease are the causes of cerebrovascular syncope (29).
Microvascular decompression for trigeminal neuralgia caused by vertebrobasilar
Absolute contraindications include fractured odontoid peg, recent cervical spine fracture, atlanto-axial subluxation, cervical disc prolapse, vertebrobasilar
insufficiency that is verified, recent neck trauma that restricts torsional movement.
In case of unilateral carotid occlusive disease, the anterior collateral segment (ACA1, AcomA) made of arteries with constant diameter is crucial, while in case of bilateral occlusive carotid disease the posterior collateralization (ACPI, AcomP) develops, with the inflow from the vertebrobasilar
8,9) De estos el que representa menos morbimortalidad y el que mejor exposicion tiene para el clipaje de aneurismas de la union vertebrobasilar
es el Abordaje Far lateral con sus variantes anatomicas.
Si esto no se cumple podria confundirse con una epilepsia del lobulo temporal, insuficiencia vertebrobasilar
, vertigo posicional benigno o alguna patologia del oido medio (50).
A repeat MRI of the brain and magnetic resonance angiography (MRA) of the cervical and intracranial vasculature were obtained (March 28) because the initial study was indeterminate as to the etiology of the parenchymal abnormalities, and to evaluate for possible vertebrobasilar
disease because of the possibility of a brainstem stroke.
4) Transient ischemia of the vertebrobasilar
According to embryogenesis of the carotid-basilar anastomoses described by Padget , there are four embryonic communicating arteries between the vertebrobasilar
and carotid systems: the hypoglossal, otic, proatlantal, and trigeminal arteries.
