Insights

Middle Meningeal Artery (MMA) embolization is a safe and effective treatment for chronic subdural hematoma (cSDH). This procedure led to complete resolution in most patients, significantly reducing recurrence risks.

Area of Science:

  • Neurosurgery
  • Interventional Radiology
  • Vascular Neurology

Background:

  • Chronic subdural hematoma (cSDH) arises from neovascularization within the subdural membrane.
  • Recurrence is common, often linked to the Middle Meningeal Artery (MMA).

Purpose of the Study:

  • To evaluate the safety and efficacy of MMA embolization for chronic subdural hematoma.
  • To assess clinical and radiological outcomes following MMA embolization.

Main Methods:

  • Retrospective review of 29 patients undergoing MMA embolization for cSDH (2018-2022).
  • Analysis included clinical history, imaging, procedural details, and outcomes.
  • Follow-up imaging (MRI/CT) and modified Rankin Scale (mRS) were assessed.

Main Results:

  • Twenty-nine MMA embolization procedures were successfully performed.
  • Complete radiological resolution occurred in 25 patients (86%).
  • Excellent functional outcome (mRS 0) at 90 days was observed in 86% of patients.

Conclusions:

  • MMA embolization is a feasible and effective treatment for chronic and recurrent cSDH.
  • The procedure demonstrates a favorable safety profile with high resolution rates.

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: 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...

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...
