- Immediate neurological and neurosurgical consultation should be obtained on patients with evidence of any SAH on imaging or lumbar puncture, irrespective of whether the SAH is likely to be aneurysmal or non-aneurysmal in nature.
- Computed tomographic angiography (CTA) of the head is helpful to determine the presence of a lesion suitable for surgical or endovascular intervention.
- The need for obtaining cerebrovascular imaging, such as CTA of the head or catheter angiography, should be discussed with neurological or neurosurgical consultant first.
- Similarly, the decision to start medications that have been shown to alter outcomes in aSAH (such as nimodipine and aminocaproic acid) should be deferred to the neurological or neurosurgical consultant.
