Ischemia of cerebral vessels is a reciprocalthe body's reaction to local oxygen starvation, due to a lack of blood supply to brain tissue. Disruption of blood flow, usually occurs as a result of narrowing of the lumen or complete blockage (thrombosis) of the cerebral arteries.
In the field of pediatric neurology, a serious problembecomes ischemia of the brain in newborns. This fact is due to the fact that until now physicians do not have sufficiently effective methods of drug treatment of the disease.
The disease is caused by various external andinternal factors. However, regardless of the causes of the occurrence of ischemia, untimely diagnosis and wrong treatment are followed by deplorable results.
Ischemia of cerebral vessels: causes
The disease appears mainly as a result ofAtherosclerosis of the cerebral vessels, which is the growth of fat deposits on the inner walls. Because of fatty layers, the lumen of the vessels gradually decreases and a partial or complete disturbance of the blood flow occurs. No less rare cases of the origin of ischemia is the clotting of the blood clot of the entire lumen of the brain artery.
Ischemia of cerebral vessels canprovoke heart failure, tachycardia, bradycardia (irregular heartbeat rhythm), increased blood viscosity due to erythrocytosis, anemia, carbon monoxide poisoning and other pathologies.
The main reason for diagnosing ischemiaof the brain in a newborn is hypoxia, expressed in the insufficient supply of children's brain with oxygen, which occurs during pregnancy and during childbirth.
Ischemia of cerebral vessels: symptoms and treatment
The earliest symptoms of the disease arerapid fatigue in mental work and active brain activity. In the future, this factor is supplemented by a significant memory impairment and forgetfulness. Clinical symptoms of cerebral ischemia include severe dizziness, sudden jumps in blood pressure, different localization of headaches, fainting, vomiting, nausea, visual and speech disorders, sensitivity disorders and general weakness.
Currently, with the diagnosis of vascular ischemiathe brain of effective methods of treatment with the help of medications has not been developed. Since the middle of the last century, medical practice has been using operational methods to correct atherosclerotic vessel injuries that feed brain tissue. The essence of surgical intervention is to remove atherosclerotic plaque or thrombus from the clogged cerebral artery, as well as restore optimal supply of the brain with blood, oxygen and nutrients. Such operations are most often performed under local anesthesia.
If surgical intervention is not possiblewe have to rely on medical treatment. To do this, appoint a means of the group of statins, fibrates, anion-exchange resins, low-molecular heparins, nicotinic acid, preparations based on fish oil. Extracorporeal purification of blood is carried out.
During illness it is necessary to change a way of lifeand eating behavior. A strict diet with a limited content of animal fats is prescribed, a dosed physical exercise is recommended, a sleep of at least 8 hours is sufficient, and emotional overvoltage is prevented.
Prevention of cerebral ischemiashould start from an early age. Doctors recommend, as closely as possible, to protect themselves from the main risk factors: obesity, hypodynamia, alcohol abuse, smoking and stress effects.
