[Aneurysmal subarachonid haemorrhage].
The most characteristic symptom of an aneurysmal subarachnoid haemorrhage (aSAH) is a sudden onset of severe headache, which can be accompanied by meningism, impaired consciousness, and vegetative symptoms. A cerebral CT scan is the initial diagnostic tool of choice if aSAH is suspected. The localisation and morphology of the aneurysm is depicted in a CT-angiography and/or conventional panangiography. Until definitive exclusion of the aneurysm by either microsurgical clipping or endovascular coiling, rebleeding should be avoided implicitly. The postoperative phase, especially in patients with severe aSAH is embossed with the occurrence of disease-specific complications (cerebral vasospasm, intracranial hypertension, seizure disorder, hydrocephalus) and consecutively increased risk for secondary brain injury. Furthermore, many patients present systemic complications such as electrolyte disturbances and cardiac dysfunctions. Early identification and therapy of cerebral and systemic complications are very important in order improve functional outcome.
