Insights

Cerebral vasospasm following subarachnoid hemorrhage remains a major cause of death and disability. This review covers current and future treatments to prevent vasospasm-induced stroke after subarachnoid hemorrhage.

Area of Science:

  • Neurology
  • Neurosurgery
  • Vascular Neurology

Background:

  • Cerebral vasospasm is a significant complication of aneurysmal subarachnoid hemorrhage (aSAH).
  • It remains a primary cause of morbidity and mortality despite advances in aSAH treatment.
  • SAH-induced vasospasm leads to reduced cerebral perfusion, causing ischemia.

Purpose of the Study:

  • To review current therapeutic options for cerebral vasospasm post-SAH.
  • To discuss future strategies for reducing vasospasm-induced stroke.
  • To highlight diagnostic modalities for SAH-induced vasospasm.

Main Methods:

  • Review of current medical and endovascular therapies.
  • Discussion of diagnostic tools including transcranial doppler, digital subtraction angiography, CT, and MR.
  • Analysis of pathophysiology including vasculopathy, impaired autoregulation, and hypovolemia.

Main Results:

  • Cerebral vasospasm can be asymptomatic or symptomatic (delayed ischemic neurologic deficit).
  • Digital subtraction angiography is the gold standard for diagnosis, while transcranial doppler is a common screening tool.
  • Medical and endovascular therapies are current treatment mainstays.

Conclusions:

  • Effective management of cerebral vasospasm is crucial for improving outcomes after aSAH.
  • Further research into novel therapeutic approaches is needed to reduce stroke incidence.
  • Early diagnosis and timely intervention are key to mitigating neurological deficits.

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
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...

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
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...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
