Abstract
ABSTRACT
Background: Stroke is the 5th leading cause of death in the United States, with one person dying every 4 minutes. It is a worldwide health problem, making a great contribution to mortality and morbidity of patients around the world. For black people, stroke is the 3rd leading cause of death. Approximately 800,000 people have a stroke each year; about one every 40 seconds. Stroke is classified as being either hemorrhagic or ischemic but the more common is the ischemic type. An ischemic stroke occurs when a cerebral vessel is occluded, obstructing blood flow to a portion of the brain. This occlusion can develop within small intracranial vessels, often because of uncontrolled hypertension or diabetes. Aim of the Work: is performed for evaluation of hemodynamics in collaterals in patients with extracranial carotid stenosis alone in comparison with patients having both extracranial and intracranial carotid stenosis in acute ischemic stroke. Patients and Methods: 30 patients with acute cerebrovascular stroke were recruited in this cross-sectional study admitted in stroke unit at the department of neurology of Ain Shams University hospitals. Results: The current study was conducted at Ain Shams University Hospitals during the period between June 2017 and March 2018. 30 subjects were included in this study, divided into two groups: 15 patients with acute ischemic cerebrovascular stroke with significant extracranial carotid stenosis ( more than 70%) detected by Carotid duplex, Another 15 patients with acute cerebrovascular stroke with BOTH significant extracranial carotid stenosis (more than 70%) detected by Carotid duplex and intracranial stenosis detected by MRA. Conclusion: Transcranial colour coded Duplex is safe, accurate, inexpensive, non‐invasive, bedside technique providing useful information on intracerebral vasculature, It was used in this study to detect that there is no difference in cerebral collaterals as ophthalmic arteriers and anterior cerebral arteries hemodynamics in cases of internal carotid stenosis alone or cases with both internal carotid and intracranial stenosis together.
