OBJECTIVE Stroke research and clinical trials have focused mainly on anterior circulation stroke (ACS). Since clinical characteristics, mechanisms, and outcomes of posterior circulation stroke (PCS) have been reported different from ACS, more PCS studies are required, particularly researching the etiologies, to help establish an optimal management strategy. METHODS The present study analyzed ...

attacks (tia’s) account for 15-23% of all ischemic strokes/tia,1,2 the prognosis is similar to anterior circulation in terms of persistent functional disability at three months.2,3 they have higher rate of recurrent strokes and tia4 and yet it is Cinderella disease. Baseline national institute of health Stroke Scale (nihSS) is falsely low in patients with pCS and may influence thrombolysis deci...

The present study evaluated the calibers and anatomic configurations based on the Magnetic Resonance analysis (MRA), assaying the cerebral vascular territories and sex-linked variations. A randomized sample of 30 angiographic examinations in adult patients of both sexes was obtained and components of the circle of Willis were identified. Branch diameters were measured on a transversal cut 5mm f...

BACKGROUND Early multicenter trials of Guglielmi detachable coil embolization of posterior circulations aneurysms have been followed by the publication of numerous single-center experiences. Summary of Review- We performed a MEDLINE literature search and extracted data from single-center reports containing at least 10 posterior circulation aneurysms. Twelve reports (495 aneurysms) were specific...

BACKGROUND we report our technical success and complication rates in treating posterior circulation aneurysms at sites other than the basilar apex, superior cerebellar artery origin, or the posterior inferior cerebellar artery origin via endovascular embolization or sacrifice. MATERIALS AND METHODS we retrospectively reviewed case records for patients undergoing coil embolization of atypical ...

background: stroke is the most common neurologic disease and an important cause of morbidity and mortality. headache is an initial presenting feature of ischemic stroke and sometimes preceedes the development of stroke and thus, provides an opportunity for offering preventive measures. the aim of the present study was to determine the association of new onset headache with stroke. methods: a to...

INTRODUCTION Bilateral thalamic infarcts are rare presentations of stroke. They are the result of a complex combination of risk factors and a predisposing vessel distribution. The artery of Percheron, characterized by a single arterial trunk that irrigates both paramedian thalamic regions, can be occluded as a result of embolic diseases leading to bilateral paramedian thalamic infarcts. Clinica...

Congenital vertebral artery (VA) hypoplasia is an uncommon embryonic variation of posterior circulation. The frequency of this congenital variation was reported to be 2-6% from autopsy and angiograms. Is it a congenital risk factor of ischemic stroke? In this review, we gave an overview of the literature concerning vertebral artery hypoplasia. VA hypoplasia served as an independent factor of a ...

Acute basilar artery occlusion is a neurological emergency. Unlike anterior circulation stroke presenting with hemiparesis, the symptoms of basilar artery occlusion are challenging to recognise in the emergency setting. Basilar artery occlusion can rarely lead to ischaemia of the auditory pathways, resulting in bizarre, positive auditory hallucinations. Here, we report two cases of basilar arte...
