Ischemic stroke
After subarachnoid hemorrhage delayed onset vasospasm can result in devastating ischemic stroke.
Ischemia results if blood flow to the brain is below 18 to 20 ml per 100 g per minute, and tissue death occurs if flow dips below 8 to 10 ml per 100 g per minute.
Epidemiology
Ischemic stroke is a leading cause of mortality and morbidity worldwide, and atherosclerosis is one of the major risk factors for this neurologic deficit.
Classification
Risk factors
Pathophysiology
In brain tissue, a biochemical cascade known as the ischemic cascade is triggered when the tissue becomes ischemic, potentially resulting in damage to and death of brain cells.
Treatment
see Ischemic stroke treatment.
Complications
see Ischemic stroke complications.
Outcome
