Abstract

Insights

Particle embolization for brain tumors (meningiomas) carries risks of stroke and bleeding. Careful consideration of the benefits versus these potential complications is essential for patient care.

Area of Science:

  • Neurosurgery
  • Neuroradiology
  • Vascular Interventional Radiology

Background:

  • Preoperative embolization is a common procedure for meningiomas.
  • It aims to simplify surgical removal and minimize blood loss during surgery.

Purpose of the Study:

  • To determine the incidence of neurological complications associated with particle embolization of intracranial meningiomas.
  • To assess complications occurring during and after the embolization procedure.

Main Methods:

  • A retrospective analysis of 185 patients who underwent particle embolization for intracranial meningiomas between 1996 and 2004.
  • Superselective catheterization of tumor-feeding arteries followed by embolization with spherical particles under systemic heparinization.

Main Results:

  • A total of 6.4% of patients experienced procedure-related neurologic complications.
  • Ischemic events (stroke) occurred in 3.2% of patients (2 with amaurosis, 4 with hemiparesis).
  • Hemorrhagic complications also occurred in 3.2% of patients, with one fatality due to massive hemorrhage.

Conclusions:

  • Particle embolization of meningiomas is linked to significant risks of both ischemic and hemorrhagic complications.
  • The decision to proceed with embolization requires a thorough evaluation of the individual patient's risk-benefit profile.

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: 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...

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...

Cytotoxic Edema: Pathophysiology

Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
