The SPARTA study is a prospective multicenter observational trial in the Netherlands with the aim of identifying the best clinical care in patients with aneurysmal subarachnoidal haemorrhage. Differences in outcome between surgical treatment and endovascular treatment will be explored.
Furthermore, cost effectiveness and radiological prognostic factors will be examined.
Confirmed diagnosis of subarachnoid haemorrhage on CT-scan or lumbar puncture (in the presence of a negative CT-scan)
Intracranial aneurysm proven within 6 months to be the cause of subarachnoid haemorrhage
Age 18 years or over at presentation.
Written informed consent
Subarachnoid haemorrhage deemed most likely of 'perimesencephalic' origin after consideration of history, clinical examination and radiological findings (including angiographic imaging)
Subarachnoid haemorrhage deemed most likely of post-traumatic origin after consideration of history, clinical examination and radiological findings (including angiographic imaging)
Diagnosis of intracerebral arteriovenous malformations or dural arteriovenous fistula.
No diagnosis of intracranial aneurysm at 6 months after onset of symptoms.
