Summary
Brain death was diagnosed in a 69-year-old woman following subarachnoid hemorrhage. Absence of intracranial circulation confirmed the diagnosis due to her unstable condition preventing an apnea test.
Area of Science:
- Neurology
- Neurosurgery
- Critical Care Medicine
Background:
- Subarachnoid hemorrhage (SAH) is a critical neurological emergency.
- SAH can lead to severe neurological deficits, including coma and brainstem dysfunction.
- Timely diagnosis of brain death is crucial for patient management and organ donation considerations.
Observation:
- A 69-year-old female patient presented with deep coma and absent brainstem reflexes post-SAH.
- The patient's vital signs were unstable, precluding the standard apnea test.
- Computed tomographic angiography (CTA) demonstrated a complete absence of intracranial circulation.
Findings:
- The clinical presentation and diagnostic imaging findings were consistent with brain death.
- CTA is a valuable tool for confirming the absence of cerebral blood flow in cases where the apnea test cannot be performed.
- The diagnosis of brain death was established based on clinical signs and CTA results.
Implications:
- This case highlights the utility of CTA in diagnosing brain death when standard testing is contraindicated.
- Accurate and timely diagnosis of brain death is essential for clinical decision-making and ethical considerations.
- Understanding alternative diagnostic methods is vital in neurocritical care settings.
