Refers to the other parts of the extracorporeal various emboli with the blood into the intracranial artery, resulting in arterial occlusion, causing local brain tissue due to ischemia and hypoxia necrosis, softening of the disease. The emboli have heart-derived and non-cardiac (such as lung trauma, surgery, long bone fractures, etc.) two categories. Chinese medicine also belongs to the "stroke" category.
The clinical manifestations of cerebral embolism are often due to the nature of emboli, the number of emboli, the location of embolization, primary disease and individual differences.
1. Consciousness disorder about half of patients with onset of a short, varying degrees of disturbance of consciousness, if the aorta and vertebral - basilar artery embolization may be a block of coma.
2. The most common symptoms of neurological deficits were contralateral hemiplegia, partial sensory disorder and hemianopia. Dominant hemisphere lesions and verbal dysfunction.
3. Seizures a small number of large vascular embolism, often caused by cerebral vasospasm, focal attack or epilepsy attack.
4. Cardiac embolism also palpitation, chest tightness and difficulty breathing.
5. Infective emboli have fever and other symptoms of infection, such as the development of pus suppository, there are intracranial hypertension symptoms, such as headache, vomiting and visual impairment, severe hernia occurred.
Rheumatic heart disease caused by young people as much, coronary heart disease and aortic disease caused by more in the elderly.
Sudden onset, in a few seconds or minutes of symptoms that peak, is the fastest incidence of all stroke, a small number of patients due to repeated embolism can be ladder in a few days increased. The general incidence of no obvious incentives, quiet and activities can be disease.
1 brain CT examination: low density area prompted infarct site.
2 EEG: visible diffuse slow wave rhythm, to the lesion side.
3 ECG: may have arrhythmia and changes in myocardial infarction.
4 chest X-ray examination: can be found in metastatic brain embolism and brain fat embolization of the lung genitals.
(1) mostly sudden onset.
(2) Most prodromal symptoms.
(3) general awareness or short-term awareness of obstacles.
(4) symptoms and signs of the internal carotid artery and / or vertebral-basilar artery system.
(5) lumbar puncture cerebrospinal fluid should generally not contain blood, if the red blood cells can be considered hemorrhagic cerebral infarction.
(6) the source of emboli can be divided into cardiogenic and non-cardiac, but also accompanied by other organs, skin, mucosal and other embolic symptoms.
