AbstractPatients with a ruptured intracranial aneurysm should be treated as soon as possible after the haemorrhage to prevent rebleeding and to allow vigorous treatment of ischemic events in case of vasospasm. The choice of treatment, endovascular or surgical, should be based on the angio-architectural aspects of the aneurysm. 3D rotational subtraction angiography will more clearly show the aneurysm morphology and will therefore help in the decision-making process. If an aneurysm is suitable for endovascular treatment ('coiling'), this should be the treatment of first choice, as has been clarified in the ISAT study. Location of the aneurysm only influences the treatment decision in aneurysms located at the basilar artery bifurcation. These aneurysms are preferably treated by endovascular means. The long-term results of endovascular and surgical treatment are still the subject of debate. For both treatment modalities, re-growth of the treated aneurysm has been described, but solid comparative data is missing. In analogy with the ISAT, referral of patients with a ruptured intracranial aneurysm should be performed as soon as possible after the haemorrhage. Preferably, this should be a hospital where neurosurgeons, interventional neuroradiologists, as well as neurologists (with expertise on medical treatment of patients with a subarachnoid haemorrhage) collaborate.
