Angiography of cerebral vessels

Now one of the most effective and high-tech examination methods used in vascular diseases is angiography of cerebral vessels. This kind allows you to visualize all the human organs and vessels of any size, so the doctor can make a conclusion about the presence of an aneurysm, blockage and tumors. In addition, often angiography is used to prepare for surgery.

Indications for angiography

This procedure is required in such situations:

• a prolonged headache, which traditional methods can not cope with;
• feeling of discomfort in the cervical region;
• dizziness, which is not associated with a change in body position;
• nausea, which is not caused by eating;
• frequent syncope ;
• congenital heart disease;
• violation of blood circulation in tumors.

Emergency angiography is prescribed for:

• intraoperative diagnostics;
• limb ischemia;
• lesions and injuries of blood vessels;
• the probability of rethrombosis or recurrent embolism.

MRI angiography of cerebral vessels

This procedure involves the use of a magnetic tomograph, which allows you to get the best image. MR angiography is used for aneurysms of cerebral vessels, to confirm the existence of stenosis and occlusions. This method is the safest way to obtain information about the characteristics of the vessels, their functioning and the processes occurring in them. Cerebral angiography allows you to eliminate the need for contrast formulation to get information about the vessels of the brain. However, if it is necessary to investigate tumors, then contrasts are used. The result of the survey is a picture of the vessels with their detailed arrangement.

CT angiography of cerebral vessels

This method is also used to conduct a study of the state of the brain vessels. In the course of the survey, three-dimensional images are obtained, which make it easy to create angiographic pictures and to study organs at the necessary angle. With the computer method of angiography, obtaining information about the vessels of the brain passes using a contrast iodine-containing substance, which, when passing through the organs, allows you to obtain the most detailed pictures during scanning. The advantage of MSCT (multi-helical computer angiography) is the ability to study a brain vessel with a diameter of up to 1 mm and obtain its image at any angle in projections that are inaccessible to conventional methods, such as cranio-caudal.

The examination is as follows:

1. Before the procedure begins, two milliliters of contrast is injected intravenously to check the body's reaction.
2. Having convinced in absence of an allergy , enter a substance in a vein of a forearm or a brush.
3. The doctor watches the contrast of the vessels for a while, then takes pictures.
4. After processing images in special programs, visualize the vessels in different projections.

Contraindications to angiography of cerebral vessels

As the procedure can provoke some complications, the following groups of persons are prohibited from carrying out such an examination:

• having intolerance components of iodine-containing contrast (in this case gadolinium compounds are assigned);
• in the acute course of mental illness;
• with chronic diseases of internal organs;
• in the acute stage of myocardial infarction;
• suffering from renal failure, because of which it is impossible to remove contrast from the body;
• if there are problems with blood coagulability;
• pregnant women.
