BACKGROUND AND PURPOSE Dolichoectasia of the basilar artery is a characteristic finding of Fabry disease. However, its prevalence, severity, and course have been poorly studied. This study quantitatively evaluated, by MRA, a panel of basilar artery parameters in a large cohort of patients with Fabry disease. MATERIALS AND METHODS Basilar artery mean diameter, curved length, "origin-to-end" li...

Pharmacological differences between canine and monkey basilar arteries were studied in vitro. The constrictor response of canine basilar artery to either norepinephrine or an alpha 1-adrenoceptor agonist phenylephrine was partly inhibited by an alpha 2-adrenoceptor antagonist yohimbine but not by an alpha 1-adrenoceptor antagonist prazosin. The contraction elicited by an alpha 2-adrenoceptor ag...

background: headache is one of the most disturbing symptoms with common neurological signs. variations in optic nerve perfusion quality or retinal microcirculation may end up in ganglion cell damage in patients with migraine. methods: sixty patients diagnosed with migraine and thirty normal individuals were evaluated in groups including migraine with aura, migraine without aura and controls. re...

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 by an intramural dissection within t...

The incidence of basilar artery fenestration is approximately 0.6% in angiographic studies and more in autopsy studies [1]. The most common site of basilar artery fenestration is proximal part [2]. Basilar artery fenestration aneurysms are very rare, posing unique challenges. Reported incidence of aneurysm at basilar artery fenestration site is 7% [3]. Surgical treatment of such aneurysm is usu...

abstract background: migraine is a primary headache disorder that affects the neurovascular system. recent studies have shown that consumption of some fatty acids such as omega‑3 fatty acids improves migraine symptoms. the aim of the present study is to assess the association between usual intake of fatty acids such as eicosapentaenoic acid (epa), docosahexaenoic acid (dha), and saturated fatty...

background: recent evidences have supported migraine headache and neurally mediated syncope as the especial types of endotheliopathies. to determine endothelial function in patients with migraine headache or those with neurally mediated syncope,the present study was conducted. materials and methods: this cross-sectional study was performed on 93 consecutive patients aged 5-20 years in four grou...
