Summary

Subarachnoid hemorrhage patients with specific CT findings and declining neurological status may have clinically significant vasospasm. Early detection of subtle signs is crucial for timely intervention and improved outcomes.

Area of Science:

  • Neurology
  • Neurosurgery
  • Critical Care Medicine

Background:

  • Subarachnoid hemorrhage (SAH) is a critical condition often leading to delayed cerebral ischemia.
  • Cerebral vasospasm is a major cause of morbidity and mortality following SAH.

Purpose of the Study:

  • To outline the characteristic clinical and diagnostic features of clinically significant cerebral vasospasm after SAH.
  • To emphasize the importance of early recognition and intervention for patients at risk.

Main Methods:

  • Review of clinical presentation and diagnostic findings in patients with confirmed vasospasm post-SAH.
  • Correlation of patient demographics, admission grade, CT findings, and laboratory results with vasospasm development.

Main Results:

  • High-risk patients include adults with SAH 4-9 days prior, poor admission grade, and thick subarachnoid blood on CT.
  • Patients may present with low-grade fever, elevated WBC count without infection, worsening headache, neck stiffness, and subtle neurological changes.
  • Key laboratory findings include decreased serum sodium concentration.

Conclusions:

  • Clinically significant vasospasm has recognizable features that warrant vigilant monitoring.
  • Early identification of subtle neurological deterioration and specific clinical/radiological markers is essential for prompt management.
