Primary and secondary graft patency rate of
all grafts.
Primary patency rate is 76%, 65%, 47% and 33% and secondary patency
rate is 83%, 71%, 58% and 41% at 2, 5, 10 and 15 year after bypass
surgery, respectively. |

affecting primary graft patency. The figure in a parenthesis
means year of the longest observation after surgery. |

Patency rate of failing graft and failed graft
after revision surgery.
Patency rate of failing graft vs. failed graft is 73 vs. 56%,
59 vs. 49%, 49 vs. 49% at 1, 2 and 5 year, respectively. There
is no significant difference. (p = 0.4381) |
