Higher numbers of circulating endothelial progenitor cells in stroke patients with intracranial arterial stenosis
BACKGROUND Bone marrow-derived endothelial stem cells participate in vascular repairs. Numbers of circulating endothelial progenitor cells (cEPCs) are associated with atherosclerosis. Fibrinogen plays a key role in atherosclerosis. Objective was to assess if cEPC counts were associated with atherosclerotic intracranial artery stenosis (IAS). METHODS Three hundred subjects (108 patients with s...
متن کاملTreatment of atherosclerotic intracranial arterial stenosis.
Atherosclerotic stenosis of the major intracranial arteries (intracranial internal carotid artery, middle cerebral artery, vertebral artery, basilar artery) is probably the most common cause of stroke worldwide.1 Intracranial atherosclerosis causes 30% to 50% of strokes in Asia2 and 8% to 10% of strokes in North America.3 This review focuses on the medical and endovascular treatment of atherosc...
متن کاملTransorbital Doppler diagnosis of intracranial arterial stenosis.
Forty-two intracranial internal carotid arteries were visualized by both arteriography and 2 MHz pulse ultrasonic Doppler examinations. The intracranial internal carotid artery Doppler signals were studied at 5-7 cm depth behind the eyelid using frequency spectral analysis. Stenosis criteria were developed and methods of avoiding confusion with collateral effects devised. Among 33 intracranial ...
متن کاملAssociation of Lp-PLA2 Mass and Aysmptomatic Intracranial and Extracranial Arterial Stenosis in Hypertension Patients
OBJECTIVE Intracranial arterial stenosis (ICAS) is a common cause of ischemic stroke in Asians, whereas whites tend to have more extracranial lesions. Lipoprotein-associated phospholipase A2 (Lp-PLA2) has been associated with ischemic stroke by a large amount of work. However, there are few studies focusing on the relationship of Lp-PLA2 and asymptomatic ICAS or extracranial arterial stenosis (...
متن کاملPathophysiology of extracranial cerebral arterial stenosis--a critical review.
THE PURPOSE OF THIS REVIEW IS to discuss the phenomenon of stenosis in extracranial cerebral arteries, its effects on normal blood flow patterns and the biological and clinical implications for the extracranial cerebral circulation. Stenosis, generally defined as a narrowing or constriction, is of particular interest because of its potential to decrease blood flow. Stenosis of the extracranial ...
