• Cannulation before two weeks of age should be avoided.
• Cannulation between two to four weeks may be attempted but
only if the fistula is considered mature.
• Cannulation after four weeks of maturation may be safe, if the
fistula is mature.
Independent of the age of the fistula, clinical examination prior to
cannulation is very important, given that some fistulas require up
to six months to mature.
Grafts can be cannulated for hemodialysis
earlier than fistulas.
Grafts can usually be cannulated within weeks.
Some times within days of surgery

35. COMPARISON OF FISTULAS
• Primary failure
defined as an access that never provided reliable
hemodialysis.higher in native AVF
• Patency/secondary failure
In native fistulas the risk of secondary failure is
low. Higher with synthetic graft
• local complications :bleeding , Thrombosis,
infection, and seromas occur more frequently
with grafts than with fistulas
