  abstract  = {Background: Severe brain edema is observed in a number of patients suffering from subarachnoid hemorrhage (SAH). Little is known about its pathogenesis and time-course in the first hours after SAH. This study was performed to investigate the development of brain edema and its correlation with brain perfusion after experimental SAH. Methods: Male Sprague-Dawley rats, randomly assigned to one of six groups (n = 8), were subjected to SAH using the endovascular filament model or underwent a sham operation. Animals were sacrificed 15, 30, 60, 180 or 360 minutes after SAH. Intracranial pressure (ICP), mean arterial blood pressure (MABP), cerebral perfusion pressure (CPP) and bilateral local cerebral blood flow (LCBF) were continuously measured. Brain water content (BWC) was determined by the wet/dry-weight method. Results: After SAH, CPP and LCBF rapidly decreased. The decline of LCBF markedly exceeded the decline of CPP and persisted until the end of the observation period. BWC continuously increased. A significant correlation was observed between the BWC and the extent of the perfusion deficit in animals sacrificed after 180 and 360 minutes. Conclusions: The significant correlation with the perfusion deficit after SAH suggests that the development of brain edema is related to the extent of ischemia and acute vasoconstriction in the first hours after SAH.},

  abstract  = {This article reviews experimental and clinical data on the use of various neuroprotective agents and therapeutic measures after aneurysmal subarachnoid hemorrhage (SAH). While calcium antagonists have been used in the past and are still part of the standard treatment regimen in most departments involved in the treatment of SAH, other classes of drugs and various other methods have been tested for their potential to inhibit delayed ischemia after SAH. This article reviews the literature about clinical studies about the efficacy of various neuroprotective agents and methods including statins, steroids and Endothelin-antagonists and other - alternative - methods like cisternal lavage, intrathecal drug delivery and hypercapnia, offering future perspectives for the treatment of this hazardous disease.},
