Pathophysiology of Hemorrhagic Stroke
Pathophysiology of Hemorrhagic Stroke
Cerebral hemorrhage including third of all cases the main cause of cerebral vascular disorders. Cerebral hemorrhage can occur outside the dura mater (extradural hemorrhage or epidural), under the dura mater, (subdural hemorrhage), in the subarachnoid space (subarachnoid hemorrhage) or in the substance of the brain (intracerebral hemorrhage). Extradural hemorrhage (epidural) is a neuro surgical emergency requiring immediate treatment. This is usually followed by a skull fracture rips meningeal artery with other arteries. Subdural hemorrhage (including acute subdural hemorrhage) is basically the same with epidural hemorrhage, subdural hematoma normally except that the bridge torn vein. Therefore, a longer period of hematoma formation (obviously longer intervention) and cause pressure on the brain. Some patients may experience chronic subdural hemorrhage without showing signs and symptoms. Subarachnoid hemorrhage can occur as a result of trauma or hypertension, but the most common cause is leaking aneurysm, in the area of the circle of Willis, and congenital arteriovenous malformation in the brain. Arteries in the brain may be a place aneurysm. Intracerebral hemorrhage is most common in patients with hypertension and cerebral atherosclerosis, due to degenerative changes due to this disease usually causes rupture of blood vessels. in people younger than 40 years, intracerebral hemorrhage is usually caused by arteriovenous malformations, haemangioblastoma and trauma, also caused by certain types of arterial pathology, brain tumors and the use of medications (oral anticoagulants, amphetamines and various drug additives). Bleeding is usually an artery, and occurs mainly around the basal ganglia. Usually sudden onset with severe headache. When hemorrhage enlarged, the more obvious neurological deficits that occur in the form of loss of consciousness and abnormalities in vital signs. Patients with extensive bleeding and hemorrhage decreased consciousness and abnormalities in vital signs.
