Vascular access is the mainstream in dialysis patients.
is known that complications after vascular access construction are associated to increased morbidity and mortality.1,2
There are two main types of vascular access: native arteriovenous fistula and arteriovenous graft.
Arteriovenous fistula is the favorite access for hemodialysis.
The goal is to create a long-standing functional vascular pathway.
multidisciplinary approach is crucial to increase the lifetime of the vascular access.3,4 Fig. 1
it is very important for the radiologist to know that there is countless variability in the veins and arteries of the upper limb.
hemodynamic issues and pathological conditions,
pre and post fistula construction,
should be recognized and discussed with a multidisciplinary team.
