What is an arteriovenous fistula?
What is an arteriovenous graft?
- If you have small veins making fistula formation difficult, you can get a vascular access that connects an artery to a vein using a synthetic tube, or graft, implanted under the skin in your arm. A graft doesn’t need to develop as a fistula does, so it can be used sooner after placement, often within 2 or 3 weeks. Grafts tend to have more complications like clotting and infection and need replacement sooner
What is a venous catheter?
What are the complications of AV fistula?
All three types of vascular access av fistula, av graft, and venous catheter can develop complications. The most common complications are access infection and low blood flow due to blood clotting.
Venous catheters are most prone to develop infection and clotting problems that may require medication and catheter removal or replacement.
AV grafts can also develop both these complications. In case of clotting, av graft may require angioplasty ( a procedure to widen the narrowed segment) or replacement.
These complications are less common in av fistulas.
