DIAGNOSTIC TECHNIQUE FOR ARTERIOVENOUS FISTULA STENOSIS IN LONG-TERM HEMODIALYSIS PATIENTS WITH END-STAGE CHRONIC RENAL DISEASE Russian patent published in 2014 - IPC A61B5/00 G01N33/483 

FIELD: medicine.

SUBSTANCE: arteriovenous fistula stenosis in long-term hemodialysis patients with end-stage chronic renal disease is diagnosed by four or more criteria: mean corpuscular volume (MCV) more than 93.3 ml, mean corpuscular hemoglobin (MCH) of more than 32.2 pg/l, urea concentration (Urea) more than 15.9 mmole/l, post-dialysis urea (Ur_KT/V) more than 4.2 mmole/l, mid-dialysis urea (Ur_PCR) more than 4.5 mmole/l, as well as dialysis efficacy (Kt/V) less than 1.71 units and equilibrated Kt/V (Kt/Veqv) less than 1.54 units.

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