Prevalence of Intracranial and Extracranial Arterial Stenosis in Ischemic Stroke Patients in Badr University Hospital

Abstract

Stroke is the primary cause of serious neurologic disability in adults and one of the main causes of mortality in the majority of nations.  According to the World Health Organization, ischemic stroke accounts for between 70 and 80 percent of all strokes and is the most prevalent form. Strokes have a global impact on 15 million individuals each year, resulting in the death of 5 million and the persistent disability of an additional 5 million. This has a significant impact on families and communities.   New research on stroke risk factors has not yet resolved the question of whether specific risk factors directly influence different levels of cerebral arteries in stroke patients. A massive ischemic stroke in the anterior circulation may occur when a major intracranial artery or one of its branches becomes blocked. Exclusion criteria included a follow-up length of one year or less for patients with end-stage renal illness.   Both low and high Cr/Cys-C values were found at the cohort median.  Kaplan-Meier analysis was used to estimate RFS and OS for patients with high vs low Cr/Cys-C levels, and Cox proportional hazards models were used to assess associations with the outcomes of interest.  In our search for connections between Cr/Cys-C and skeletal muscle mass, we employed logistic regression and correlation analysis.   Nearly 90% of infarcts and two-thirds of all initial strokes are caused by the occlusion of the middle cerebral artery (MCA) or one of its tributaries. Despite the fact that intracranial vascular damage is more prevalent in Chinese and African American stroke patients than in Caucasian stroke patients. This study's aimed to evaluate the current prevalence of intracranial and extracranial artery stenosis in patients who present with acute ischemic stroke and transient ischemic attacks (TIAs) at Badr University Hospital.Keywords: Intracranial, Extracranial, Arterial stenosis, Ischemic stroke.
