Angiography

Angiography is an x-ray examination of blood vessels. An X-ray contrast agent is injected into the patient's artery, after which a series of radiographs are taken (see Arteriography). Fluorescein angiography is a widely used method for examining patients in ophthalmology. Sodium fluorescein is injected into the cubital vein, from where it is distributed throughout the human body through the blood stream. Light of a specific wavelength is directed into the patient's eye, causing the contrast agent to glow in the blood vessels of the retina. This allows you to observe the state of the blood vessels in the retina and photograph them.

Angiography is an X-ray examination of blood vessels, which is used to diagnose various diseases such as atherosclerosis, thrombosis, aneurysm, stenosis and others. During angiography, a special contrast agent is injected into the patient's artery, which allows the blood vessels to be visualized on X-ray images.

One of the most common angiography methods is arteriography, in which a contrast agent is injected directly into the artery. This allows you to get a more accurate picture of the condition of the blood vessels and identify possible pathologies.

However, angiography can be dangerous for the patient, especially if the contrast agent contains iodine. Therefore, before conducting the study, it is necessary to ensure that there are no contraindications and carry out the necessary preparation.

In ophthalmology, fluorescein angiography is also used. It consists of injecting a special substance, sodium fluorescein, into the patient’s vein. Then, using light of a certain wavelength, a fluorescent glow occurs in the blood vessels of the retina. This allows you to see the condition of the vessels and photograph them.

Thus, angiography is an important method for diagnosing various diseases of the circulatory system. However, before conducting the study, it is necessary to carry out the necessary preparation and ensure that there are no contraindications.

Introduction Angiography is one of the most effective methods for diagnosing diseases of the human circulatory system. It is based on the use of X-ray radiation, which makes it possible to detect defects and changes in the walls of arteries and veins.

Angiography: why do we need X-ray control? The test involves injecting a contrast agent into a vein in the arm, which is then distributed throughout the body through the circulatory system. The drug is usually called “needle” or “contrast”. What does angiography provide? The method makes it possible to detect all sections of arteries and even veins, determine the number of vessels and foci of abnormal growth. If necessary, it is possible to study the functioning of not the entire blood flow system, but of a specific section of it. Usually the brachial, iliac, knee and femoral arteries are examined. There is another method of studying blood vessels - duplex scanning of the vessels of the neck and head. This way the doctor will assess the current state of the vessels, that is, see where they are, what degree of narrowing they have, and whether there are any obstacles to the blood flow. But this type of examination is only available to people of a certain age. Children have soft blood flow, which is difficult to see on a regular monitor. Therefore, it is impossible to use ultrasound for them. What
