Insights

Carotid web (CW) and CW with plaque show distinct ultrasonic and clinical features. Web length predicts stenosis in CW, while stenosis and plaque length indicate symptoms in CW with plaque.

Area of Science:

  • Vascular Neurology
  • Medical Imaging
  • Cardiology

Background:

  • Carotid web (CW) is a congenital anomaly that can lead to stroke.
  • Distinguishing between CW and CW with plaque is crucial for risk stratification.
  • Understanding risk factors for stroke in CW patients is essential for prevention.

Purpose of the Study:

  • To compare clinical and multimodal ultrasonic characteristics of CW versus CW with plaque.
  • To identify potential risk factors for stroke associated with CW.

Main Methods:

  • Retrospective analysis of 299 patients diagnosed with CW via CTA or HRMRI.
  • Utilized contrast-enhanced ultrasound (CEUS) and superb microvascular imaging.
  • Employed logistic regression to identify stroke risk predictors.

Main Results:

  • Significant differences observed in clinical and ultrasonic features between CW and CW with plaque groups.
  • Web length independently predicted luminal stenosis in CW patients.
  • Luminal stenosis and plaque length were identified as risk factors for symptoms in CW with plaque patients.

Conclusions:

  • Multimodal ultrasound and clinical data reveal substantial differences between CW and CW with plaque.
  • Web length is a key predictor of carotid stenosis in CW.
  • Luminal stenosis and plaque length are associated with stroke symptoms in CW with plaque.

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 I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

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)...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

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...
