Phlebography Renal

Renal phlebography

Renal phlebography is a radiopaque examination of the renal veins, in which a contrast agent is injected selectively into the renal veins through a catheter installed in the inferior vena cava.

When performing phlebography of the kidney, a radiologist, under fluoroscopic control, inserts a catheter into the inferior vena cava and places its tip at the mouth of one of the renal veins. A contrast agent is then injected through the catheter, which fills the renal vein and its branches. On the obtained X-ray images, the renal veins are contrasted, which makes it possible to evaluate their anatomy and identify pathological changes.

Renal phlebography helps diagnose renal vein thrombosis, varicose veins, compression of veins by a tumor or other causes. This study can also be used to evaluate the results of surgical treatment of renal vein diseases.

Renal phlebography is a procedure for visualizing the internal structures of an organ using X-rays or computed tomography. To obtain information about the blood supply to the kidney, a radiocontrast agent is used, which is injected into a vein and distributed throughout the body. The examination allows you to assess the condition of the renal vessels, identify any disturbances in the functioning of the organ, and determine the presence of stones and other neoplasms.

Before the procedure begins, the patient is injected with a contrast solution, which facilitates visualization. Then a special catheter is installed in the inferior vena cava, from where the contrast enters the renal veins. If necessary, the doctor can direct the diagnosis of blood vessels in a separate direction. During the examination, the patient lies on his back to achieve the maximum diagnostic effect.

The results of kidney phlebography can be used to diagnose and treat many diseases. It helps determine the cause of pain or hypertension, as well as detect tumors and other neoplasms. In addition, venography is one of the stages before kidney or heart surgery, when more accurate visualization of the blood supply is necessary.

It is important to note that renal vein phlebography may have side effects, such as an allergic reaction to the contrast agent and damage to the vessel wall. Therefore, the procedure is carried out only when necessary and under the supervision of a doctor.
