Hand Acceleration Time (HAT) Assessment Before and After Creating an Arteriovenous Fistula (AVF)

The main objectives of this observational study are to compare the results of the sonographic parameter hand acceleration time (HAT) measured before and after creating an arteriovenous fistula (AVF) for hemodialysis and assess if it is associated with the incidence of hemodialysis access-induced distal ischemia (HAIDI). The secondary objectives are to study the incidence of HAIDI in patients intervened for the creation of an AVF in the last 6 months, study the AVF permeability at 6 months, and study the AVF-related complications at 6 months.
