AVF is a communication between an artery and a superficial vein, which is created surgically, and after a maturation period of at least 6 weeks, it allows us to obtain a portion of the superficial vein of good caliber in which the blood flow is sufficiently important to allow the realization of hemodialysis. The AVF must be punctured by a nurse at each session with two large gauge needles to allow sufficient blood flow. This step, which is repeated more than 300 times a year per patient, is crucial to the success of the treatment. The quality of its execution determines the success of the treatment [The psychological aspect must be taken into account, as difficult or even painful punctures often cause apprehension in patients, even real anxiety, and can be a source of deterioration in quality of life.Finally, the quality of the AVF puncture also impacts the quality of the treatment [The population of subjects treated in hemodialysis is made up of increasingly older patients with vascular comorbidities and often diabetes. All these factors negatively influence the quality of the vessels for AVF preparation and contribute to increasing the risk of complications related to AVF puncture.
