The aim of this study was to investigate the feasibility of the simultaneous clipping of bilateral middle cerebral artery aneurysms via the unilateral pterional approach in Asian patients. The study included 10 cases of bilateral middle cerebral artery aneurysms, including two males and eight females; the ratio of male to female patients was 1:4. The patients ranged in age from 44 to 67 years o...

To determine cerebrovascular risk factors for patients with cerebral watershed infarction (CWI) from Southwest China.Patients suffering from acute ischemic stroke were categorized into internal CWI (I-CWI), external CWI (E-CWI), or non-CWI (patients without CWI) groups. Clinical data were collected and degrees of steno-occlusion of all cerebral arteries were scored. Arteries associated with the...

BACKGROUND AND PURPOSE The effects of hemodialysis on the cerebral circulation of humans and the correlation between changes in blood flow velocity in the basal cerebral arteries and those of several physiological variables influenced by hemodialysis have been inadequately studied. METHODS Blood flow velocities were obtained from the middle cerebral artery and the basilar artery by transcrani...

Objective(s): Stroke is known as a main cause of mortality and prolonged disability in adults. Both transient receptor potential V1 (TRPV1) channels and toll-like receptors (TLRs) are involved in mediating the inflammatory responses. In the present study, the effects of TRPV1 receptor activation and blockade on stroke outcome and gene expression of TLR2 and TLR4 were assessed following permanen...

BACKGROUND AND PURPOSE In contrast to middle cerebral artery territory strokes, anterior cerebral artery strokes (ACAS) occur rarely. The low frequency of ACAS, in relation to middle cerebral artery territory strokes, may be explained by differences in ACA and middle cerebral artery anatomy influencing their respective flow-directed embolism rates. We aimed to determine whether variability in A...

background: nitric oxide synthase (nos) activity is increased during hypertension and cerebral ischemia. nos inactivation reduces stroke-induced cerebral injuries, but little is known about its role in blood-brain barrier (bbb) disruption and cerebral edema formation during stroke in acute hypertension. here, we investigated the role of nos inhibition in progression of edema formation and bbb d...

From 2 hours to 23 days following experimental subarachnoid hemorrhage, the accumulation of indium-111-labeled platelets on the intimal surface of the middle cerebral artery was studied in 23 cats. Subarachnoid hemorrhage was produced by transorbital rupture of the right middle cerebral artery. Of the 23 cats, 17 exhibited right middle cerebral artery/left middle cerebral artery radioactivity r...

BACKGROUND AND PURPOSE Moyamoya disease is a well described phenomenon. This pattern of collateralization associated with isolated middle cerebral artery stenosis and the natural history of this entity have not been well described. METHODS Cerebral angiograms and CT angiograms performed between August 2004 and August of 2006 demonstrating moyamoya collateralization were retrospectively review...
