Background The middle cerebral artery (MCA) supplies a major part of the brain and is considerable clinical importance as common location intracranial aneurysms. aim present study was to analyze bilateral MCAs in patients with unilateral

Dissection of the internal carotid artery is often caused by trauma to the face or neck. It usually has a delayed onset neurological presentation, a partial middle cerebral artery territory syndrome, 'normal' early CT scan, MRI evidence of middle cerebral artery occlusion, progressive partial or complete neurological recovery, and duplex scan evidence of a reestablished lumen in the internal ca...

BACKGROUND AND PURPOSE Interhemispheric inhibition via the corpus callosum has been proposed as an exacerbating factor in outcome from stroke. METHODS We measured infarct volume and behavioral outcome after middle cerebral artery occlusion in callosotomized rats and acallosal mice. RESULTS Neither callosotomy in rats nor callosal agenesis in mice improved infarct volume or behavioral outcom...

The arterial supply of the feline motor cortex is derived from both the anterior and middle cerebral arteries. The anterior cerebral artery supplies most of cortical area 6 (premotor cortex), the intrafundal cruciate and medial postcruciate cortex, (hindlimb motor cortex), and the midline and medial portions of the sensory areas 3a-7. The middle cerebral artery supplies the lateral prorean cort...

Background and Purpose—Interhemispheric inhibition via the corpus callosum has been proposed as an exacerbating factor in outcome from stroke. Methods—We measured infarct volume and behavioral outcome after middle cerebral artery occlusion in callosotomized rats and acallosal mice. Results—Neither callosotomy in rats nor callosal agenesis in mice improved infarct volume or behavioral outcome af...

BACKGROUND AND PURPOSE Thrombosis of the cerebral venous sinus may cause venous congestion, cerebral edema, and infarction. The role of cerebrovenous disorders in arterial ischemic stroke is unknown. The objective of this study was to examine the contribution of ipsilateral cranial venous abnormalities to the development of cerebral edema in middle cerebral artery infarction. METHODS This is ...
