Research summary
Subarachnoid haemorrhage (SAH) is caused when a weakening in a blood vessel (aneurysm) ruptures. It is a potentially devastating condition which carries a high risk of death and disability. Patients who present to hospital with symptoms of SAH undergo brain imaging to confirm the cause is an aneurysm. In a proportion of patients the pattern of bleeding on brain imaging suggests the cause is not due to an aneurysm (non-aSAH) and for these patients the outcome is usually excellent. However, there is no gold-standard method for brain imaging in patients with no obvious aneurysm; making it difficult for doctors to confirm the diagnosis and ultimately affecting how well patients recover.
This project will explore the reasons for why some doctors use different imaging for patients with non-aSAH and will measure the effect of this choice on patient outcome. This research will examine the records for all patients treated at a single neurosurgical centre over a 7 year period. The project aims to compare the different types of imaging and assess the affect the choice of imaging had on patient outcome. The results of the project may assist doctors in their choice of imaging in the future and ultimately lead to improved outcome for patients with non-aSAH.REC name
