Intracerebral%20hemorrhage Signs and Symptoms
Definition
- Intracerebral hemorrhage (ICH) is the result of a blood vessel rupture within the brain and the blood leaks out to form a hematoma
- Accumulated blood compress, distort and disrupt surrounding brain structures
- Sudden onset of focal or global cerebral dysfunction is manifested
- Focal neurologic findings are related to the anatomic location, size and speed of development of ICH
- Neurological deficit usually progresses over a minute to an hour
Epidemiology
- Most common manifestation of a chronic, progressive disorder of the brain’s blood vessels and affects more than 2 million people annually worldwide
- Accounts for 10-20% of all strokes
- Global incidence rate of stroke due to hemorrhage was 15-40%, with >15% observed more in Asia compared to developed countries in North America and Western Europe
- Incidence increases at 55 years old and continues to increase with age
- Age-standardized stroke prevalence rates of ICH was high in East and Central Asia
- Men are more likely to experience ICH than women
- In 2017, among the 6.2 million deaths caused by cerebrovascular disease globally, 3 million deaths were due to ICH
- Mortality rate was highest in East and Southeast Asia
Pathophysiology
- Non-traumatic ICH is most often caused by blood vessel rupture secondary to hypertensive damage
- May also be caused by structural abnormalities such as vascular malformation, neoplasm, or inflammation
Etiology
Primary Causes
- Arterial hypertension
- Cerebral amyloid angiopathy (CAA)
Secondary Causes
- Cerebral venous and sinus thrombosis
- Sinus thrombosis
- Deep cerebral venous thrombosis
- Cortical venous thrombosis
- Vascular malformation
- Arteriovenous malformation
- Dural arteriovenous fistula
- Cavernous malformation
- Intracranial neoplasms
- Primary intracerebral tumors
- Metastases
- Coagulopathies
- Congenital bleeding disorders
- Coagulopathic liver disease
- Trombocytopenia
- Drug-induced coagulopathy
- Infection
- Herpes simplex virus
- Septic emboli, mycotic aneurysms
- Intracranial aneurysm
- Hemorrhagic transformation of cerebral infarct
- Vasculitis
- Moyamoya disease
Risk Factors
Modifiable
- Hypertension
- Chronic hypertension accounts for 56% of attributable risk for the incidence of ICH
- Diabetes
- Smoking
- Alcohol consumption
- Diet
- Hyperlipidemia
- Obesity (waist-hip-ratio)
- Medications (eg anticoagulants, antiplatelets, decongestants, antihypertensives, stimulants, sympathomimetics)
- Illicit drug use (eg cocaine, heroin, amphetamine)
Non-modifiable
- Advanced age
- Male sex
- Asian ethnicity
- Chronic kidney disease
- Liver disease
- Hematologic disease
- Cancer
- Recent trauma or surgery
Emergency Measures
Rapid recognition and diagnosis of ICH are essential because of frequent rapid progression
Warning Signs
- Nausea and vomiting (N/V)
- Severe headache
- Decreased consciousness or coma
- Elevated systolic blood pressure (SBP)
Initial Survey and Management
- Ensure the status of the patient’s airway, breathing and circulation
- Intubate if insufficient ventilation (pO2 <60 mmHg/7.9 kPa or pCO2 >50 mmHg/6.3 kPa), cyanosis, impending respiratory failure, obvious aspiration risk, or depressed level of consciousness
- Detection of focal neurological deficits
- Detection of signs of external trauma
- Admit in an intensive care unit (ICU) or acute stroke unit for at least the 1st 24-72 hours
