METHOD OF SELECTIVE COLLECTION OF BLOOD FROM THE RENAL VEINS WITH ABNORMALITIES OF BLOOD SUPPLY TO THE KIDNEY Russian patent published in 2018 - IPC A61M25/01 A61B6/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to X-ray surgical methods of diagnosis and treatment. Perform puncture of the right femoral arteries and veins with the installation of introducers with a diameter of 5F or 6F in these vessels. Then a diagnostic catheter is injected into the lumen of the inferior vena cava. In the aortic lumen, a diagnostic catheter is also set up, which is installed in the mouth of an additional renal artery. Then, in the process of selective angiography, an X-ray contrast preparation is introduced into the lumen of the additional renal artery in an amount of 15–20 ml before contrasting the microcapillary network of the kidney with subsequent observation of the venous phase and contrasting of the additional renal vein, including its place of confluence in the lower vena cava. Focusing on the received video image, a diagnostic catheter in the inferior vena cava is placed in the mouth of an additional vein. Contrast is repeated to control the location of the catheter at the mouth of the accessory vein, after which venous blood is taken from it. Then, venous blood is taken from the primary renal vein. Above sequence of operations is repeated on the contralateral kidney. Then both catheters are removed, the intradusers are removed and hemostasis is performed.

EFFECT: method allows to provide selective blood sampling from an additional renal vein that drains blood from that part of the kidney, which is supplemented with an additional renal artery, thereby increasing the accuracy of the diagnostic study.
