Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute 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.

Area of Science:

  • Neuropathology
  • Vascular Pathology
  • Forensic Pathology

Background:

  • Stroke is a leading cause of death and disability.
  • Autopsies frequently examine brain and relevant tissues cursorily.
  • Pathological findings and clinical implications depend on stroke type, location, and cause.

Purpose of the Study:

  • To highlight the importance of thorough autopsy examination in stroke cases.
  • To outline the diverse pathological findings associated with different stroke types.
  • To emphasize the clinical relevance of accurate post-mortem diagnosis in stroke.

Main Methods:

  • Review of pathological findings in stroke patients.
  • Correlation of autopsy findings with clinical data.
  • Discussion of common and uncommon causes of ischemic and hemorrhagic stroke.
  • Emphasis on proper autopsy preparation and examination techniques.

Main Results:

  • Large ischemic strokes often linked to atherosclerosis or dissection.
  • Small cerebral infarcts commonly caused by arteriosclerosis or cerebral amyloid angiopathy (CAA).
  • Vasculitides and coagulopathies present varied stroke patterns.
  • Subarachnoid hemorrhage primarily from berry aneurysms; parenchymal hemorrhage often due to hypertensive small vessel disease or neoplasms.
  • Global brain ischemia can mimic hypoglycemic injury.

Conclusions:

  • Adequate stroke autopsy requires meticulous preparation, knowledge of vascular anatomy, and careful gross and histological examination.
  • Understanding diverse stroke etiologies is crucial for accurate diagnosis.
  • Thorough examination improves understanding of stroke morbidity and mortality.
