THE ROLE OF SURGERY IN HEMORRHAGIC STROKE
A. DEFINITION
Definition of stroke according to World Health Organization (WHO) is the clinical signs that developed rapidly due to focal brain dysfunction (or global), with symptoms lasting 24 hours or more, and can cause death.
Stroke is a brain attack caused by blockage or sudden onset of rupture of blood vessels of the brain that causes certain brain cells are deprived of blood, oxygen or nutrients and eventually death can occur in these cells in a very short time (Stroke Foundation of Indonesia, , 2006).
Hemorrhagic stroke is rupture of the walls of blood vessels, causing bleeding in the brain. Generally occurs when patients do activities. Bleeding and impairment of consciousness are real (Stroke Foundation of Indonesia, 2006).
B. EPIDEMIOLOGY
Stroke is a major health problem in modern life today. In Indonesia, an estimated 500,000 residents each year occur suffered a stroke, about 2.5% or 125,000 people died, and the remainder mild or severe disability. Number of patients with stroke tend to increase every year, not just attack the elderly, but also experienced by those who are young and productive. Stroke can strike at any age, but which often occurs at the age of 40 years. The incidence of stroke increases with age, the older someone is, the higher the chances of developing a stroke (Stroke Foundation of Indonesia, 2006).
In Indonesia, there are no data to complete epidemiologic stroke, but the proportion of stroke patients from year to year tend to increase. It is seen from the Household Health survey report MOH in various hospitals in 27 provinces in Indonesia. The survey results showed an increase between 1984 and 1986, from 0.72 per 100 patient pada1984 to 0.89 per 100 patients in 1986. In RSU Banyumas, in 1997 stroke patients hospitalized as many as 255 people, 298 people in 1998 sebnyak, in 1999 as many as 393 people, and in 2000 as many as 459 people (Hariyono, 2006).
Stroke or cerebrovascular accident, is the most frequent cause of invalidity in the age group over 45 years in industrialized countries stroke is the third leading cause of death after heart disease and malignancy (Lumbantombing, 1984).
C. Etiology
Hemorrhagic strokes occur because one of the blood vessels in the brain ruptures or tears objec hemorrhagic stroke patients are generally more severe than non-hemorrhagic stroke. Awareness is generally declining. They are in a state of somnolence, osmnolen, spoor, or commas in the acute phase.
D. CLASSIFICATION
According to the cause can be divided into:
1) intracerebral hemorrhage
Intracerebral hemorrhage was found in 10% of all stroke cases, consisting of 80% in the hemispheres of the brain and the rest in the brainstem and cerebellum.
2) Subarachnoid hemorrhage
Subarachnoid hemorrhage is a condition where there is bleeding in the subarachnoid space which arises in the primary.
