Subarachnoid Hemorrhage

  • Paul Ellis Marik


Subarachnoid hemorrhage (SAH) is a common and devastating condition.1 Each year approximately 30,000 Americans suffer from a non-traumatic SAH. Patients who have suffered a SAH are best managed in an ICU or a specialized neurological/neurosurgical unit. Despite improved management the outcome following SAH remains poor, with an overall mortality of approximately 25% and significant morbidity amongst the survivors. The most serious complications following the initial bleed are rebleeding and cerebral vasospasm; management of patients with SAH is therefore largely directed to avoiding these complications. The risk of rebleeding (with conservative therapy) is highest in the first month, with a rate of between 20 and 30%. The mortality rate is approximately 70% for patients who rebleed. Angiographic vasospasm probably develops to some degree in most patients who suffer an SAH. However, clinically manifest vasospasm occurs in approximately 40% of patients. Fifteen to twenty percent of these patients will suffer a stroke or die despite aggressive management.
