Augmenting collateral blood flow during ischemic stroke via transient aortic occlusion.
Collateral circulation provides an alternative route for blood flow to reach ischemic tissue during a stroke. Blood flow through the cerebral collaterals is a critical predictor of clinical prognosis after stroke and response to recanalization, but data on collateral dynamics and collateral therapeutics are lacking. Here, we investigate the efficacy of a novel approach to collateral blood flow ...
متن کاملIntracranial Pressure and Collateral Blood Flow.
Leptomeningeal collateral vessels, linking the 3 major arterial territories over the surface of the brain, have been recognized for >140 years. More widespread use of advanced clinical imaging in the past decade has led to increasing recognition of the key importance of collaterals in ischemic stroke outcome. However, recent studies from several groups indicate that failure of initially good co...
متن کاملCollateral circulation.
BACKGROUND The collateral circulation plays a pivotal role in the pathophysiology of cerebral ischemia. Current knowledge of the collateral circulation remains sparse, largely because of prior limitations in methods for evaluation of these diminutive routes of cerebral blood flow. SUMMARY OF REVIEW Anatomic descriptions of the collateral circulation often focus on more proximal anastomoses at...
متن کاملINVESTIGATING THE DISTRIBUTION OF RISK FACTORS FOR ISCHEMIC STROKE AND ITS RELATIONSHIP WITH INVOLVEMENT SITE AND DURATION OF HOSPITALIZATION IN IMAM KHOMEINI HOSPITAL IN URMIA: A CROSS SECTIONAL DESCRIPTIVE STUDY
Background & Aims: Ischemic stroke is one of the leading causes of disability and death around the world. The results of various studies have shown that prevention is the most effective way to reduce stroke burden. Therefore, the present study was conducted with aim of evaluating the frequency of risk factors involved in ischemic stroke and its relationship with the involvement site and duratio...
متن کاملRecurrent stroke in patients with symptomatic carotid artery occlusion is associated with high-volume flow to the brain and increased collateral circulation.
BACKGROUND AND PURPOSE To investigate whether the risk of recurrent ipsilateral ischemic stroke in patients with symptomatic carotid artery occlusion (CAO) is related to (1) volume flow in the contralateral internal carotid artery (ICA), basilar artery (BA), and middle cerebral arteries (MCAs), and (2) intracranial collateral flow to the symptomatic side, measured in the first 6 months after th...
