Abstract

Insights

The incidence of medium vessel occlusion (MeVO) stroke is estimated at 16 cases per 100,000 people annually. This study provides crucial data on MeVO frequency, aiding future stroke prevention and treatment research.

Area of Science:

  • Neurology
  • Epidemiology
  • Vascular Medicine

Background:

  • Medium vessel occlusions (MeVOs) are a significant cause of ischemic stroke.
  • The precise incidence of MeVOs in the general population remains poorly understood.
  • Accurate incidence data is vital for understanding stroke burden and resource allocation.

Purpose of the Study:

  • To estimate the population-based incidence of medium vessel occlusions (MeVOs).
  • To provide a quantitative measure of MeVO frequency for epidemiological research.
  • To inform future studies on MeVOs' impact on stroke morbidity and mortality.

Main Methods:

  • A population-based study was conducted in Olmsted County, Minnesota.
  • Consecutive patients with acute ischemic stroke and confirmed MeVO between 2018-2020 were identified.
  • MeVO definition included occlusions at or beyond the M2, A2, P1 segments, or cerebellar arteries.

Main Results:

  • The study identified 77 patients with MeVOs from 1,718 screened.
  • The estimated incidence of MeVOs was 16 cases per 100,000 people per year.
  • An estimated 52,236 new MeVO cases occur annually in the US population.

Conclusions:

  • This study provides the first population-based incidence estimate for MeVOs.
  • While less common than large or small vessel occlusions, MeVOs represent a substantial stroke subtype.
  • Further research into acute intervention and prevention strategies for MeVOs is warranted.

Imaging Studies VII: Vascular Imaging

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
