Angioma - what is it? What types of angiomas exist?
Various disorders in the body can affecton the appearance of neoplasms. Among them, a special place is occupied by angioma. What is it and what are the reasons for its appearance? Angioma called benign tumor, which can be formed from blood or lymph vessels. It does not represent a danger to human life, but it is worth paying attention to such formations. Especially if they start to change in size, bleed, and also if unpleasant painful sensations arise.
Angioma - what is it? Types of angiomas
Modern medicine distinguishes several types of angiomas.
The first include cavernous formations (they are stillcalled cavernous). They have the form of red bumps. The cavity of the angioma is filled with blood, so it can bleed. In some cases, education can provoke an increase in the size of the area on which it is located. To the touch, cavernous angioma is soft, after pressing it easily restores the original shape. It is localized mainly under the skin, rarely sprouting deeper.
The next type is venous angioma. The color of such benign tumors reaches dark blue. They are located in the muscle tissue, under the skin, in fatty tissue. A characteristic feature is their autonomous growth.
Branchy angiomas are infrequent. They have the form of tangles of vessels that are branched. Such formations develop on the limbs of a person, in some cases on the head, face.
Another type is intraosseous angioma. What it is? It is a tumor that is located on the bones of the skull. May provoke bleeding.
What are the symptoms of angiomas
Very often in the place of education there arepainful sensations. Such a part of the body will feel a little warmer than the others. Depending on the location, the following signs may appear: heaviness in the limbs, difficulty breathing (if the tumor is formed in the nasal cavity).
Cavernous angioma is often very goodis visualized. Symptoms of appearance of tumors include increased hair growth in the affected area, as well as excessive sweating. If there is a suspicion that brain angioma develops, attention should be paid to frequent headaches, loss of consciousness, speech impairment.
Methods of therapy
There are several ways to treatneoplasms. The main goal is to stop the growth of angioma, return the functionality of the vessels. In therapy, laser beams are used. The tumor is removed by layers. The main advantage of this method is the almost complete absence of bleeding.
The second option is sclerosing. It is used for deep neoplasms. In the cavity of angioma is introduced a special substance (often alcohol). However, the procedure is rather painful and time-consuming.
Hormonotherapy is used ifthere is active growth of the tumor or its location is critical. An excellent option for the treatment of angioma is the use of low temperatures (cryotherapy). This method does not cause bleeding, pain is not felt. If the tumor is deep, then surgery is possible.
Angioma of the brain. Causes of appearance
This is one of the potentially dangerous tumors. Angioma of the brain can cause bleeding. The brain is one of the main organs in our body, therefore any disturbances in its functioning significantly affect the general state of the body. Most often, such a pathology is congenital. But severe head injuries, infectious diseases can provoke the appearance of education. A great role is played by the hereditary factor. There are such types of angioma of the brain: capillary, cavernous, venous. Symptoms of the latter are expressed especially brightly. Venous angioma of the brain can cause a stroke.
Symptoms of neoplasms in the brain
The formation of a tumor in the brain leads tosqueezing certain areas. As a result, headaches are observed. Also, a person complains of noise in the head, nausea, frequent attacks of vomiting. In the presence of angiomas, speech, thinking can be broken. Movement is poorly coordinated, in some cases paralysis occurs. Mainly the symptomatology depends on the area in which the tumor is located. Vision also suffers from the presence of a tumor.
How is a benign vascular tumor diagnosed?
Often, angioma of the brain does notmanifests, so the tumor can be found in other studies. Angiography is used for accurate diagnosis. It refers to invasive procedures, so specialist supervision is mandatory. As a rule, for carrying out this manipulation, the patient must be in the hospital.
Treatment of angioma of the brain
If the diagnosis is "brain angioma", thentreatment should be carried out immediately. The reason for this is a high risk of bleeding. However, in some cases, neoplasms disappear on their own. Only a competent specialist will conduct all the necessary studies and take control of the course of the disease. If the damaged vessels are located on the surface of the organ, then they can be removed without difficulty with the operation. At the same time, the integrity of healthy tissue will not be disturbed. For such operations, a gamma knife is used (for tumors that do not exceed 3 cm in size). But if the venous angioma of the brain is deep enough, other methods will be required.
Using a catheter into the tumor cavity,special substance. The essence of this method consists in blockage of damaged vessels, their isolation from the blood supply system. In some cases, radioactive rays are used. With their help, angioma can be completely eliminated.
Neoplasm in the liver
In some cases, the liver may be theorgan, where angioma is localized. What it is, you already know. But how are vascular tumors developing in the liver and what is their symptomatology? Often the disease does not manifest itself. However, over time, certain symptoms may appear. The person feels nausea, there are seizures of vomiting, there is a heaviness in the liver. There is a general deterioration in well-being. The most informative way to study such a disease is to use labeled red blood cells.
After diagnosing angioma of the liver, a specialistchooses a method of treatment. It can be sclerotherapy, laser use, hormonal therapy. In severe cases, surgery is performed. However, if tumor growth is not observed, there are no pain symptoms, it is not advisable to perform a surgical operation.
