The blind technique using metal needles has been the traditional method of cannulating arteriovenous (AV) accesses for haemodialysis. While most mature AV accesses can be cannulated with metal needles successfully, the incidence of miscannulation can be high in difficult accesses due to their location and depth, or in new accesses. Cannulation-related complications were reported to be as high as 31% and may eventually lead to access failure. Technical difficulty also increases following a miscannulation as infiltration and haematomas may increase the depth of the AV access.
