1024x768 normal 0 false false false en-us x-none ar-sa background and objective: numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. one physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. in this study, we can predict hem...

BACKGROUND AND PURPOSE Brain infarction localized in the anterior cerebral artery territory is rather uncommon, and its etiology has not yet been fully elucidated. METHODS Based on computed tomographic findings, 17 patients with solitary anterior cerebral artery territory infarction were selected from among 3,619 patients admitted consecutively to our institute. Patients without angiographic ...

Occlusion of the anterior cerebral artery is a rare condition. A review of CT scans from 413 patients with ischemic infarction confirmed this low relative incidence: only 3% of CT scans evidencing infarction involved the territory of the anterior cerebral artery. Four major mechanisms of anterior cerebral artery occlusion have been identified in this series: Emboli in unusual hemodynamic circum...

In 20 necropsies with 15 stenosed and 17 thrombotic occluded internal carotid arteries there were 46 cerebral infarcts larger than 1 cm diameter. Using portmortem arteriographic and pathological techniques the patterns of the neck and brain artery systems were correlated with the situation and extent of the brain infarcts. Massive infarcts involving two major cerebral artery territories were as...

background: the aim of this study is to determine the frequency of intracranial artery stenosis in patients with acute ischemic stroke in iran. methods: a total of 169 patients with acute ischemic stroke were eligible to participate and were enrolled in this study from january 2012 to february 2013. all the patients were admitted to the nemazee ‎hospital, affiliated to shiraz university of medi...

INTRODUCTION The Circle of Willis is a vascular network formed at the base of skull in the interpeduncular fossa. Its anterior part is formed by the anterior cerebral artery, from either side. Anterior communicating artery connects the right and left anterior cerebral arteries. Posteriorly, the basilar artery divides into right and left posterior cerebral arteries and each joins to ipsilateral ...

BACKGROUND Angioplasty of the intracranial vasculature has been well described for the middle cerebral artery and carotid terminus, primarily in the setting of vasospasm following subarachnoid hemorrhage. Endovascular therapy for anterior cerebral artery stenosis has not heretofore been described. CASE REPORT We report the case of A1 segment angioplasty in a 77 year old man with presumed intr...

This paper describes a case of intracerebral hiemorrhage due to rupture ofa congenital aneurysm situated on the right anterior cerebral artery. After a series of acute cerebral vascular incidents the clinical picture was that produced by a rapidly expanding frontal lesion. After full investigation, including air encephalography, the diagnosis of ruptured anterior cerebral aneurysm was made and ...
