What is hypertensive encephalopathy

What is hypertensive encephalopathy
Hypertensive encephalopathy is a sharp increase blood pressure (diastolic blood pressure in general more than 17.3 kPa) lead to cerebral edema and intracranial压升高, caused a change in Jizhou of clinical syndrome, and often occurred in radical minority of hypertension and ease into the hypertensive病人. Also seen in acute glomerulonephritis, pregnancy-induced hypertension, renal hypertension and pheochromocytoma, and other patients. Clinical sudden rise in blood pressure, headache, vomiting, irritability, seizures and unconsciousness as the main performance.

Headache to diffuse the whole headache, the amount before or after the main pillow, coughing or forced aggravating, often accompanied with nausea and vomiting.

Disturbance of consciousness are more common, light to make them apathetic, fuzzy consciousness, lethargy, weight, coma, and with hemiplegia, Pianmang, aphasia and bust dysfunction.

Hypertensive encephalopathy convulsion attack is another common symptom, performance or limitations for systemic convulsion, serious form of status epilepticus. Twitch is due to the emergence of the continuing role of intracranial hypertension, brain tissue focal necrosis, the brain caused by abnormal discharge.

Hypertensive encephalopathy fundus examination, the foreseeable edema, or optic nerve head with intravenous circuitous thinning, such as Yinsi kind, or arteriovenous cross, with a retinal bleeding. Lumbar puncture CSF examination showed increased pressure, increase the protein content of or containing a small amount of red blood cells and interleukin.

Hypertensive encephalopathy for more CT scan shows no abnormalities performance or cerebral edema, brain hemorrhage and this is the basis for the identification of one.

The pathogenesis of hypertensive encephalopathy, is not very clear, because the majority of that sudden rise of blood pressure and cerebral artery self-regulation caused by the disorder. Under normal circumstances, high blood pressure and cerebral arteries to contract, not the brain arteries over filling; blood pressure dropped, the small cerebral artery relaxation to ensure that the blood supply to the brain so that the intracranial pressure to maintain the normal range. However, the rapid increase blood pressure, this regulatory function disorders, brain arteries sustained and strong contraction, then the Mandatory diastolic passive and in the brain and excessive infusion of cerebral edema, and produce a series of intracranial压升高Symptoms.

Hypertensive encephalopathy is a serious complication of hypertension, if not timely rescue, due to continued increased intracranial pressure, irreversible brain damage or death due to cerebral hernia formation and, therefore, it is necessary to closely observe the condition, the prevention of hypertension Encephalopathy in the event of a rescue treatment should be positive.
