[Pitfalls of anesthesiologic management in operative or interventional securing of aneurysm]

Despite significant advances in operative, interventional and perioperative management aneurysmal subarachnoid hemorrhage is still associated with high rates of 30-day mortality in 35% and severe impairments in neurologic functional outcomes in up to 50% of the survivors. Apart from severity of initial brain injury prognosis depends on the extent of secondary brain injury triggered by re-rupture, vasospasm, hydrocephalus and/ or further operative, interventional or intensive-care associated complications. Due to the complexity of disease the paper exclusively deals with pitfalls of anesthesiologic management in operative and non-operative aneurysm repair.
