What is Transient Cerebral Thrombosis?
By transient ischemic attack (TIA) refers to a short time (less than 24 hours) the loss of parts of the brain function caused by a transient occlusion of an artery in the brain or in brain afferent arteries.
The most common symptoms are transient (under 24 hours) hemiplegia of arm and leg or unilateral facial paralysis, possibly combined with the loss of parts of the visual field. You can have speech difficulties, and it can pinch to find the words. Space and sense of direction can also be affected. Sensory disturbances and difficulty controlling the arms and legs may also occur.
How does the disease?
TCI has a benign course, because the symptoms are completely gone after the attack, which lasts from a few hours up to a day.
Often heralds TCI of impending permanent stroke with persistent symptoms, why it is important to seek medical help.
Who gets the disease?
Men are more often TCI than women and the incidence increases significantly with age. People who suffer from obesity, who smoke, have high blood pressure or diabetes, are at greatest risk for TCI.
What is the cause of TIA (Transient cerebral thrombosis)?
TCI is due to a momentary narrowing or blockage of an artery in the brain.
Studies in TIA (Transient cerebral thrombosis)
The doctor will conduct a study of the nervous system, where you to perform small exercises that can uncover problems of coordination, gait, reflexes, etc. There are also made often a CT or MRI scan of the brain to rule out bleeding in the brain. There may also be carried out ultrasonic testing of the blood vessels leading to the brain, and the brain’s blood vessels to find constrictions in blood vessels.
Treatment of TIA (Transient cerebral thrombosis)
What can I do?
The key is to reduce the risk of the emergence of new blood clots in the brain. You should stop smoking, and you should exercise regularly. In addition, you must be treated with medicines that lower the risk of new blood clots.
The risk of ischemic stroke (stroke) within 3 months after TCI can be reduced by about 80% starting treatment with antiplatelet agents within 24 hours. Optionally, the treatment is supplemented with blood pressure medications and cholesterol lowering agents.

By narrowing of the arteries in the neck of more than 70% may be possible by further radiography of the blood vessels (arteriography) remove the restriction by surgery.
These agents inhibit clumping of platelets and therefore prevents blood clots. Platelets, which are small cells in the blood, affects the formation of blood clots in the arteries, especially the coronary arteries (heart attack) and in brain arteries (blood clot in the brain).
Acetylsalicylic acid is a widely used anti-platelet agent. To prevent blood clots required much smaller doses than when aspirin used as painkillers. 75 mg per day is sufficient. You do not achieve stronger preventive effect at higher doses, greater risk of side effects.
Dipyridamole is used with aspirin to prevent blood clots in the brain. Dipyridamole has a vasodilatory effect, which in some patients can cause headaches.
Clopidogrel is used to prevent blood clots in brain arteries as an alternative to aspirin and dipyridamole. Clopidogrel is also used with aspirin in certain people with heart attack and in cases where there used a stent during balloon expansion of the coronary arteries.
Glycoprotein inhibitors (Abciximab, Eptifibatide) is used to prevent blood clot formation in connection with balloon dilation of arteries. They are used only in hospitals.
Epoprostenol is only used to prevent the blood clump together in needles and tubes associated with dialysis treatment.
Prasugrel is used with aspirin for up 12 months to prevent new blood clots and to prevent complications of acute myocardial infarction in patients treated with balloon angioplasty (PCI, percutaneous coronary intervention).
Ticagrelor used to prevent blood clots in patients who have a heart attack. The treatment can last up to 12 months and is administered with aspirin.
