Insights

This study presents two cases where pure motor hemiplegia, a lacunar stroke syndrome, developed during cardiac angiography, suggesting an embolic cause for lacunar infarction.

Area of Science:

  • Neurology
  • Cerebrovascular Diseases
  • Embolic Stroke

Background:

  • Lacunar infarcts are small, deep cerebral infarcts often linked to hypertension.
  • The embolic origin of lacunar infarction remains debated, lacking direct causal proof.
  • Cardiac embolization is a potential, though unproven, cause of lacunar syndromes.

Observation:

  • Two patients developed pure motor hemiplegia during cardiac or aortic arch angiography.
  • Neither patient had prior stroke or transient ischemic attack history.
  • Initial brain CT scans were normal; one later showed a lesion consistent with infarction.

Findings:

  • The presented cases suggest that emboli can precipitate lacunar stroke syndromes.
  • Pure motor hemiplegia, a classic lacunar stroke, was observed to have an embolic basis.
  • Cerebral infarction occurred in a patient undergoing arterial imaging procedures.

Implications:

  • These findings support the hypothesis that emboli can cause lacunar infarction.
  • The study highlights a potential mechanism for lacunar stroke in specific clinical contexts.
  • Further research may elucidate the role of emboli in lacunar stroke etiology.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Cardiac Catheterization I: Pre-Procedure Overview

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Cardiac Catheterization III: Left Heart Catheterization

Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...

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...
Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
Transient Ischemic Attack l: Introduction01:26

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...
