Hemorrhagic Stroke ll: Pathophysiology

30
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...

Area of Science:

  • Neurology
  • Vascular Surgery

Background:

  • Cerebral hyperperfusion syndrome (cHS) is a rare complication following cerebrovascular procedures.
  • It can manifest with diverse neurological symptoms, including stroke-like presentations and delayed hemorrhage.
  • Incidence of cHS after carotid endarterectomy is reported between 0-3%.

Purpose of the Study:

  • To present a case of a 78-year-old woman diagnosed with cerebral hyperperfusion syndrome.
  • To highlight the importance of considering cHS in patients experiencing clinical deterioration post-procedure.

Main Methods:

  • A 78-year-old female patient with acute ischemic stroke in the middle cerebral artery (MCA) territory underwent endovascular embolectomy.
  • A Solitaire(®) device was used for successful recanalization, despite partial thrombotic material dislocation into the anterior cerebral artery (ACA).

Main Results:

  • The patient experienced an acute ischemic stroke with right-sided hemiparesis and aphasia.
  • Successful recanalization of the MCA was achieved, but complications arose due to thrombotic material displacement.

Conclusions:

  • Cerebral hyperperfusion syndrome should be suspected in patients with neurological decline after successful recanalization.
  • Prompt diagnosis and management of cHS are vital for optimizing neurological recovery after endovascular embolectomy.
