Hemorrhagic Stroke

Excerpt

Cerebrovascular accident (CVA), otherwise called a stroke, is the third major cause of morbidity and mortality in many developed countries. Stroke can be either ischemic or hemorrhagic. Ischemic stroke is due to the loss of blood supply to an area of the brain. It is a common type of stroke.

Hemorrhagic stroke is due to bleeding into the brain by the rupture of a blood vessel. Hemorrhagic stroke may be further subdivided into intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH). ICH is bleeding into the brain parenchyma, and SAH is bleeding into the subarachnoid space. Hemorrhagic stroke is associated with severe morbidity and high mortality. Progression of hemorrhagic stroke is associated with worse outcomes. Early diagnosis and treatment are essential given the usual rapid expansion of hemorrhage, causing sudden deterioration of consciousness and neurological dysfunction.
