This article addresses current critical care management strategies for patients with aneurysmal subarachnoid hemorrhage (SAH) and ischemic stroke. The chronology of typical SAH care is discussed, with an emphasis on the treatment of poor-grade SAH and on current monitoring techniques. Acute diagnosis and treatment of the life-threatening ischemic strokes is reviewed, emphasizing the care of patients with acute basilar artery occlusion and the malignant middle cerebral artery syndrome. Up-to-date estimates of the long-term outcomes of these syndromes are reviewed.
