Utility analysis of management strategies for suspected subarachnoid haemorrhage in patients with thunderclap headache with negative CT result
Conclusions
CT with no follow-up was shown to be the best strategy when the pre-test probability of SAH is low (<1.6%) or the sensitivity of initial non-contrast CT for blood is high (>99.6%). Otherwise, LP should be the preferred strategy for follow-up.
