Abstract

Insights

Multiple intracerebral haemorrhages are rare, but linked to numerous microbleeds and high blood pressure. Strict blood pressure control may prevent secondary haemorrhages in patients with multiple microbleeds.

Area of Science:

  • Neurology
  • Radiology
  • Neurosurgery

Background:

  • Multiple simultaneous intracerebral haemorrhages (ICH) are rare with an unknown mechanism.
  • This study investigates clinical factors associated with multiple ICH, including microbleeds.

Purpose of the Study:

  • To compare clinical factors of multiple ICH with single ICH.
  • To discuss potential explanations for the occurrence of multiple ICH.

Main Methods:

  • Included 190 consecutive ICH patients admitted within 24 hours.
  • Compared clinical factors, including microbleeds on T2(*)-weighted MRI, between single and multiple ICH groups.

Main Results:

  • Nine patients had multiple ICH, all with >= 5 microbleeds on MRI (significantly higher than single ICH).
  • Systolic blood pressure >= 200 mmHg was observed in 7/9 multiple ICH patients (higher than single ICH).

Conclusions:

  • Elevated blood pressure from initial ICH may cause secondary haemorrhages in patients with multiple microbleeds.
  • Strict blood pressure control is suggested to prevent multiple ICH.

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

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...
