Blood clots in the head – symptoms, cause and treatment

Blood clots in the head – symptoms, cause and treatment

Blood clots: these are the first signs!

A blood clot consists of coagulated blood, and is formed, for example, in the case of injuries. Blood clotting is essential for life, in order to satisfy the flow of blood and to prevent Bleeding to death. However, this “wound closures” can have deadly consequences, if you clog the blood vessels, the vital organs with the blood supply – such as, for example, in the head.

Key facts – An Overview

  • Blood clots are made up of coagulated blood.
  • While such clots serve to stop the loss of blood, in the veins of the brain is fatal. When they clog blood pathways, the brain receives no oxygen, and a stroke is imminent.
  • A stroke announces itself with paralysis, speech problems, and movement disorders. If this symptoms, the Affected must seek medical assistance immediately, because every Minute of it damages the brain more.
  • Blood clots in the head are often fatal, many of the Survivors suffer from damage to the most severe paralysis.

Symptoms

Blood clots in the brain can lead to a stroke. Symptoms of this are:

  • A sudden onset of paralysis, usually on one side of the body,
  • lack of strength in legs and arms,
  • a one-sided feeling of numbness,
  • Blurred vision,
  • the disturbed equilibrium,
  • Dizziness,
  • Speech problems such as Mumbling or speech loss,
  • Loss of consciousness,
  • severe headache,
  • Uncertainty when walking and Standing.

How pronounced are the symptoms?

How pronounced are the symptoms of a blood clot in the head, depends on in what region of the brain the clot sits. The above-mentioned symptoms occur, you need to contact, however, in each case immediately for an ambulance or the rescue service.

Not all blood clots in the head lead to a stroke. So can occur, for example, without a stroke (cerebral infarction), short visual disturbances such as double vision or eye flicker. Even so, you should immediately seek medical help.

The F-A-S-T Test

With the F-A-S-T Test, you can check whether it is a stroke.

  • F – Face: ask the person to smile. With a half-sided facial paralysis that’s not possible.
  • A – Arms: Ask the patient to lift the arms at the same time. This shows whether the arms are paralyzed.
  • S – Speech: have the Affected simple sentences to speak. A slurred speech speaks for a stroke.
  • T – Time: Call itself with a low suspicion of an emergency doctor immediately. Every Minute counts.

Causes of blood clots

Blood clots develop in different ways. In case of injury, the body responds to the stimulus. The blood vessels constrict to slow the flow of blood. In damaged tissue, the platelets are activated – platelets. These collect in the wound and form a clot that closes this. On proteins, hardening the cap and protect the wound from bacteria, viruses, fungi and other contaminants.

Injuries don’t have to be on the outside. Also damaged inner vessel walls, for example, in the case of atherosclerosis, the bonding of blood platelets.

Even without injuries, these clots develop when blood flows slowly or is jammed. This also allows platelets to accumulate and clog the veins.

Heart defects and tumours

Heart defects promote blood clots – particularly the heart rhythm disturbance and atrial fibrillation. Here the blood is spun so upset that blood clots can arise, however, not in the head, but in the atrium of the heart.

Tumors, and inborn mutations cause the blood to clot too quickly and clots so clumped.

Accidents

After fractures, surgeries, and serious diseases Concerned to move the appropriate part of the body, often less. Skull fractures or bone injuries of the cervical spine lead to a lifting of the head, lower, or rotate. Thus, the muscles are going to waste, the transport is usually the veins presses and so the blood back to the heart..

This pressure of the muscles is missing, the blood flows more slowly and accumulates in the veins. Now it comes to a flow of blood, platelets and Gerinnungsgstoffe collect. Here can form a blood clot in the head.

The blood can lead to congestion in other parts of the body to blood clots in the head. Parts of a thrombosis can dissolve and by the blood circulation Hiking, up in the vessels that supply the head.

Clot out eyes

A few years ago, a new method to remove dangerous blood clot in the head was established. It is called mechanical Thrombectomy. This opens, in practice, nine out of ten patients in the sealed vessel. So-called Stents catch on in a kind of basket, the clot. You suck it so to speak.

Originally, these Stents were in Germany, intended Outgrowths of the brain to treat vessels. They are suitable for clots, which block major cerebral arteries. The Stent is a tiny device made of wire and pushes the clot to the vessel wall. The clumped platelets migrate to the Inside of the “basket” and are now “pulled like a caught fish”. The Stent is pushed through a catheter up into the brain.

The Lysis Therapy

This is the conventional therapy, to eliminate a blood clot in the head. Here is a drug (recombinant tissue plasminogen activator) is passed through the corresponding vein into the bloodstream. The drug thins the blood and dissolves the clot.

Local and systemic thrombolysis

As the lysis therapy can be used, depends on the time. A systemic thrombolysis, the drug running of the blood circle, is a maximum of up to four and a half hours after the onset of stroke. A local treatment in which Doctors send a catheter up to the blood clots push and the coagulation-solver right there, for up to six hours after the attack.

The Secondary Prophylaxis

If you have clots is a tendency to the blood, helps a secondary prophylaxis, to prevent. At greater risk you should take this therapy for a lifetime. The best-known drug for Aspirin.

Operation

A blood clot in the head can be only a few of the Affected the surgery. This Operation is time-consuming and risky. The smallest error can trigger brain injury, and thus, depending on the seat of the Clot, life-long disabilities, from loss of speech and motor problems, paralysis, disorders of consciousness or the loss of mental abilities.

To be able to be operated on, must be the clot in the vicinity of large vessels, otherwise the surgeon will not be able to reach it.

Long-term consequences

Blood clots in the head can cause long-term damage. How big is the brain area involved and how long the Area was not supplied with blood. Ischemic attacks are relatively harmless. Here it comes to the engine misfires, the form but after about 24 hours.

More serious is the interference in Speaking and Swallowing. These, through suffering, about 70 percent of all Affected, and in many of these. Also, Defects in the memory and of the concentration of anchor often for the long term. The same goes for paralysis.

It can arise not least, new diseases and stroke. A certain Form of epilepsy.

Course of the disease

The course of the disease varies between patients. The therapy is successful, spend Affected is almost always time in a rehabilitation clinic. Here, specialists from different disciplines work together to make the patient a way back into everyday life. Physio – and occupational therapists to train movements and coordination, speech and language therapists, the disturbances in Speaking and Swallowing.

Add to this the psychological/psychotherapeutic assistance. A very common consequence of impact moderate to severe depression are seizures. Usually the Affected four-to-six weeks in a rehabilitation clinic.

Forecast

A blood clot in the head is a serious matter. The prognosis depends on the location of the event and the duration of the reduced supply of the brain. One in five dies in the first month after the stroke. Of the Survivors suffered 50 per cent permanent damage in varying degrees, such as speech impairment, paralysis or memory loss. Many are in need of care. The less brain mass has been damaged, the better the chances of a cure.(Dr. Utz Anhalt)
