[Is non-invasive monitoring of arteriovenous fistulas using temperature monitoring a good test for stenosis?].
BACKGROUND
A well functioning vascular access is essential for hemodialysis patients. A major cause of vascular access dysfunction is the development of venous stenosis. Early detection of developing stenosis could prolong their life. Elevated recirculation can detect vascular failure.


METHODS
In the period of 13 months we measured recirculation using blood temperature monitor (BTM) in 26 patients.


RESULTS
We obtained 140 measurements and found recirculation in 11 (42.3%) patients. All 11 patients underwent contrast venograms, and 8 Duplex sonography in addition. Ten (38.4%) patients received percutaneous transluminal angioplasty, 5 of them with stent placement, for severe stenosis.


CONCLUSIONS
Vascular access blood monitoring, along with preventive interventions, should be the standard of care in chronic hemodialysis patients. By treating stenosis early, it is possible to prolong the patency of vascular access.
