Keryn Davidson on aneurysms, vasospasm, clipping, and the art of watching the patient

Subarachnoid haemorrhage management requires a patient-centered approach that prioritizes clinical assessment over rigid adherence to numerical data. Vascular neurosurgeon Keryn Davidson emphasizes that subtle bedside signs, such as agitation or personality changes, often herald neurological deterioration before imaging confirms it. Effective care involves balancing the risks of vasospasm and delayed cerebral ischemia through proactive monitoring and timely intervention, while maintaining a collegial, multidisciplinary environment between neurosurgery and intensive care. Surgical decisions, such as choosing between clipping and coiling, rely on individual patient needs rather than dogmatic preferences. Beyond human clinical practice, Davidson applies her neurosurgical expertise to veterinary cases, highlighting the importance of anatomical precision and adaptability. Throughout her career, she has navigated the challenges of a male-dominated field by advocating for inclusive, evidence-based practices and maintaining resilience in the face of complex surgical outcomes.
