SCREENING DIAGNOSTIC TECHNIQUE FOR ARTERIOVENOUS FISTULA STENOSIS IN PATIENTS WITH END-STAGE CHRONIC RENAL DISEASE Russian patent published in 2014 - IPC G01N33/48 

FIELD: medicine.

SUBSTANCE: patients being treated by program hemodialysis is analysed for a complex of blood thrombocytes (X₁, ×10⁹/_l), urea concentration (X₂,^mole/_l), phosphor concentration (X₃, ^mole/_l), transferrin concentration (X₄, ^g/_l), calcium concentration (X₅, ^mole/_l) in blood serum, and a dialysis effectiveness coefficient Kt/V_equ (X₆, units), and then a discriminant function (DF) is calculated by formula. If the derived DF value is positive, the presence of arteriovenous fistula stenosis is diagnosed.

EFFECT: using the declared technique enables diagnosing the presence or absence of any stenosis changes in an arteriovenous fistula with a probability of more than 95 percent without additional laboratory and clinical studies that enable projecting a minimum surgical repair as may be necessary.
