Manual strangulation can cause watershed ischemic stroke, leading to significant neurological deficits. This case highlights the severe brain injury risk from strangulation, even without cervical vessel damage.

Area of Science:

  • Neurology
  • Vascular Neurology
  • Forensic Medicine

Background:

  • Ischemic stroke can result from various causes, including trauma.
  • Manual strangulation is a form of trauma that can compromise cerebral blood flow.
  • Watershed infarcts occur in areas between major arterial territories, often due to hypoperfusion.

Observation:

  • A 36-year-old male presented with right hemiparesis (grade IV motor deficit) and expressive aphasia.
  • Radiological imaging confirmed ischemic stroke in the left middle cerebral artery territory and watershed areas of the left anterior and posterior cerebral arteries.
  • No cervical vessel injury was identified on investigation.

Findings:

  • The patient's ischemic stroke was directly attributed to manual strangulation.
Keywords:

  • The mechanism involved hemodynamic compromise leading to hypoperfusion and subsequent infarction.
  • Cerebral injury occurred despite the absence of direct trauma to the cervical vasculature.

    • Implications:

    • This case underscores the potential for severe neurological damage, including ischemic stroke, from non-lethal strangulation.
    • It highlights the importance of considering strangulation as a cause of stroke, particularly in younger individuals.
    • Understanding the hemodynamic mechanisms is crucial for diagnosis and management in similar forensic cases.
