Angiography of all organs and systems
Angiography of all organs and systems is a study of the blood vessels to accurately determine the location and degree of the vessel narrowing.
Angiography of all organs and systems is a study of blood vessels. It is carried out in order to accurately determine the place and degree of narrowing of the vessel, the place and size of the pathological expansion of the vessels (aneurysm), pathological vascular formations (malformations), the probable place of internal bleeding, and the extent of the spread of the tumor process. It is also performed when non-invasive methods do not yield any results.
How is angiography performed?
During the angiographic procedure, an X-ray contrast substance is injected into a blood vessel through a catheter (a thin tube), which moves through the vessel together with the blood that allows the doctor to see the image of the vessel on the screen. Immediately after the introduction of the substance, a series of X-ray images is taken. Depending on the type of angiography, the place of injection of contrast enhancement can be different (arteries and veins of different locations). As a rule, angiography is performed under local anesthesia.
The puncture site is treated with an antiseptic solution and anesthetized with a local anesthetic. After that, a blood vessel (vein or artery) is punctured with a special needle. After the needle is inserted into the vessel, a conductor is inserted into its lumen. The needle is removed, and a catheter (thin tube) is introduced into the vessel through the conductor, which is guided under fluoroscopic control to the place where angiography is to be performed. As soon as the catheter is in the right place, a contrast agent is injected directly through its lumen and the entire process is recorded in the computer memory. After the procedure, the catheter is carefully removed. The puncture site is pressed with a finger, after which a bandage is applied.
What does the patient feel during the procedure?
During the injection of the contrast agent, the most common are feelings of heat or discomfort in the injection area, much less often patients note nausea or dizziness (during cerebral angiography), a feeling of lack of air or discomfort behind the sternum (during angiopulmonography).
How to prepare?
- Do not eat for two hours before the procedure, we recommend drinking water.
- Take all the usual medications.
- It is advisable to take blood test results (creatinine, blood urea) with you.
