Association between vertebral artery hypoplasia and posterior circulation stroke
BACKGROUND The clinical significance of vertebral artery (VA) hypoplasia is under discussion. The aim of this retrospective study is to evaluate a hypothesis of a possible causal link between VA hypoplasia (VAH) and the incidence of posterior circulation stroke (PCS) or TIA depending on the degree of VAH and vascular risk factors. METHODS A total of 367 symptomatic (PCS or TIA) and 742 asympt...
متن کاملIs vertebral artery hypoplasia a predisposing factor for posterior circulation cerebral ischemic events? A comprehensive review.
Vertebral artery hypoplasia is not currently considered an independent risk factor for stroke. Emerging evidence suggest that vertebral artery hypoplasia may contribute to posterior circulation ischemic events, especially when other risk factors coexist. In the present literature review, we present published data to discuss the relationship between a hypoplastic vertebral artery and posterior c...
متن کاملPosterior communicating artery aneurysm associated with duplicated posterior communicating artery and bilateral fetal posterior cerebral arteries.
Because of the location, skull-base chordomas often present with headaches and diplopia and sixth and fifth nerve palsies are the most common neurological signs.[1,2] The interval between onset of symptoms and diagnosis of clival chordoma is quite variable, 2.5-4.4 years.[4] The uncommon clinical presentations include: Nasal obstruction, nasal bleeding, and subarachnoid hemorrhage.[3,5] Spontan...
متن کاملBilateral Superior Cerebellar Artery Embolic Occlusion with a Fetal-Type Posterior Cerebral Artery Providing Collateral Circulation
Bilateral infarction of the superior cerebellar arteries with sparing of the rest of the posterior circulation, particularly the posterior cerebral arteries, is an uncommon finding in neurological practice. Most commonly, the deficits of the superior cerebellar arteries and posterior cerebral arteries occur together due to the close proximity of their origins at the top of the basilar artery. A...
متن کاملPosterior communicating artery hypoplasia as a risk factor for acute ischemic stroke in the absence of carotid artery occlusion.
Posterior communicating artery (PCoA) hypoplasia is a fetal variant of the Circle of Willis. According to angiograms and autopsy reports, this congenital variation is found in 6-21% of the general population. PCoA hypoplasia only becomes a risk factor for ischemic stroke in the presence of ipsilateral internal carotid artery (ICA) occlusion. The aim of our study was to determine the role of PCo...
