Direct phlebottensiometry, or phlebography, is used to diagnose venous diseases. The method allows you to assess the condition of blood vessels and identify pathological changes. It is based on the introduction of a contrast agent into a vein and subsequent study of its movement through the vessels.
Phlebography is performed using a special device that provides contrast injection and obtains images of blood vessels. The procedure is performed on an outpatient basis and takes no more than 15 minutes.
Before performing phlebography, the doctor conducts an examination, which includes taking an anamnesis, examining and palpating the veins, as well as assessing the condition of the skin and subcutaneous tissue. The patient is then injected with a contrast agent, which allows the veins to be seen on x-rays.
After the procedure, the patient may experience slight discomfort, but this usually goes away within a few hours. In some cases, side effects such as nausea, dizziness and allergic reactions may occur.
In general, venography is a safe and effective method for diagnosing venous diseases, which allows identifying pathological changes in the early stages.
