Impaired cerebrovascular reactivity with steal phenomenon is associated with increased diffusion in white matter of patients with Moyamoya disease.
BACKGROUND AND PURPOSE Reduced cerebrovascular reactivity (CVR) with steal phenomenon is an independent predictor for stroke and may indicate tissue exposed to episodic low-grade ischemia. The apparent diffusion coefficient (ADC) calculated using diffusion-weighted MRI is effective in characterizing focal brain ischemia and subtle structural changes in normal-appearing white matter (WM). We hyp...

Moyamoya disease is a rare vaso-occlusive illness with an unknown etiology characterized by stenosis of the internal carotid arteries with spontaneous development of a collateral vascular network.A 15-month-old girl was referred to the emergency ward of Imam Reza Hospital due to decreased level of consciousness, focal seizures and fever during the previous 24 hours with an impression of encepha...
متن کاملSteal phenomenon at unclamping during carotid endarterectomy.
A patient is reported who during vigorous back bleeding after unclamping of the internal carotid artery during endarterectomy had EEG slowing and a postoperative increase in neurological deficit. This phenomenon, an apparent steal, has not been reported and suggests that EEG monitoring is as vital at unclamping as it is after clamping. The patient also raises questions about the risk of early e...
متن کاملCerebral arteriovenous malformations associated with moyamoya phenomenon.
Cerebral arteriovenous malformations (AVMs) are associated with a variety of alterations in the angioarchitecture of the feeding arteries and draining veins [1-3]. Between January 1985 and December 1988 we examined the angiograms of 97 patients with cerebral AVMs to assess their potential for endovascular treatment. Two patients showed occlusion of major vessels and an associated moyamoya pheno...
متن کاملMoyamoya phenomenon after radiation for optic glioma.
The role of radiotherapy in the management of patients with optic pathway glioma is controversial. In a series of patients with optic pathway glioma treated at The Hospital for Sick Children in Toronto, five children were encountered who developed moyamoya phenomenon after radiotherapy. A retrospective review of the medical records was undertaken in order to assess the relationship between opti...
