Insights

Symptomatic intracranial atherosclerosis (SIA) affects nearly 10% of Caucasian patients hospitalized with acute cerebral ischemia. Key risk factors include diabetes and hypertension, highlighting the need for improved detection strategies.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Diagnostic Imaging

Background:

  • Limited data exists on symptomatic intracranial atherosclerosis (SIA) prevalence in Caucasian populations.
  • Acute cerebral ischemia (ACI) is a significant health concern with various underlying causes.

Purpose of the Study:

  • To investigate the prevalence of SIA in Caucasian patients hospitalized with ACI.
  • To identify risk factors associated with SIA in this demographic.

Main Methods:

  • Prospective, multicenter Transcranial Doppler sonography (TCD) study.
  • Inclusion of consecutive ACI patients over 24 months.
  • Diagnosis of >50% intracranial stenosis using SONIA trial criteria, confirmed by angiography (MRA/CTA) and evidence of cerebral infarction.

Main Results:

  • SIA was identified in 9.2% of 467 ACI patients (43 individuals).
  • The most frequent locations for SIA were M1MCA (34.9%) and TICA (18.8%).
  • Diabetes mellitus (OR: 4.25) and hypertension (OR: 2.41) were independently associated with SIA.

Conclusions:

  • SIA prevalence is nearly 10% in Caucasian patients with ACI.
  • Findings suggest a need for enhanced collaborative efforts among stroke physicians for SIA detection.
  • Further research may refine diagnostic yield and management strategies for SIA in Caucasian ACI patients.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
