What is ligation of AV graft?
Arterial venous graft ligation is frequently an emergent procedure that requires incision and closure. Ruptured hematoma, pseudoaneurysm, aneurysm, or abscess can be life-threatening with unstable vital signs. Any delay in operation can significantly enhance the chance of morbidity and death.
How long does an AV graft last?
AV grafts can be safely used in about two weeks, as no maturation of the vessels is necessary. Grafts have a lifespan of approximately 2 to 3 years but can often last longer. However, AV grafts can be more troublesome than AV fistulas.
What does an AV graft feel like?
At first, your fistula will feel soft and pliable and at this point, it’s still somewhat fragile. With time, however, the increased blood flow through the fistula will help strengthen it. As your fistula becomes stronger, it will feel different. Instead of being soft and pliable, it may become firm and springy.
Does AV graft need to mature?

What type of graft is Gore Tex?
GORE-TEX® Stretch Vascular Grafts have met the challenges of the most demanding vascular procedures. Recognized for exceptional performance and quality, they have earned the endorsement of renowned surgeons worldwide.
Why is ligation of AV fistula?
The AV Fistula Ligation study showed that ligation of the hemodialysis AV fistula in stable post–renal transplant patients improves LV remodeling and also reduces NT-proBNP at 6 months.
How long does it take for an AV graft to mature?
Arteriovenous fistulas can take between 6-12 weeks to mature and arteriovenous grafts can generally be used 2-3 weeks after surgery.
Can you put an IV in an arm with a fistula?
It is acceptable to use the arm with the nonfunctioning AV fistula for IV access. However, care must be taken not to use the specific vein that is occluded (typically, the cephalic or basilic vein).
