Insights

Delayed cerebral ischemia (DCI) following subarachnoid hemorrhage (SAH) is a critical complication. Research on DCI after SAH has surged, with recent focus on its pathophysiological mechanisms.

Area of Science:

  • Neurology
  • Neurosurgery
  • Cerebrovascular Diseases

Background:

  • Subarachnoid hemorrhage (SAH) is a severe cerebrovascular disease with high mortality and disability.
  • Delayed cerebral ischemia (DCI) is a major complication of SAH, significantly impacting patient outcomes.
  • Understanding DCI after SAH is crucial for improving patient prognosis.

Purpose of the Study:

  • To conduct a bibliometric analysis of global research on DCI after SAH.
  • To identify research trends, status, and hotspots from 2013 to 2022.
  • To provide a scientific reference for researchers in the field of DCI after SAH.

Main Methods:

  • Bibliometric analysis of publications from the Web of Science Core Collection (2013-2022).
  • Data analysis and visualization using VOSviewer software.
  • Systematic review of 3436 articles.

Main Results:

  • Annual increase in publications on DCI after SAH.
  • The United States leads in publications and citations.
  • Harvard University and World Neurosurgery are leading institutions and journals.
  • Recent research hotspots focus on the pathophysiological mechanisms of DCI after SAH.

Conclusions:

  • DCI after SAH has garnered significant academic interest over the past decade.
  • This study offers a comprehensive analysis of the DCI after SAH literature.
  • Current research hotspots concentrate on the pathophysiological mechanisms of DCI after SAH.

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.
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 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...
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...
