If you doctor told you that you need to get hemodialysis treatment, then you need to create a hemodialysis access for the future dialysis treatment. There are 3 types of hemodialysis accesses: an AV fistula, an AV graft and a catheter. Each of them has different pros and cons. The most popular is an AV fistula. In this article, we will talk about what is an dialysis fistula and A fistula Pros and Cons.
What is a dialysis fistula?
A dialysis fistula is also called an AV fistula, which is created by a surgery. The surgery directly connects an artery and a vein, which can create more blood flow in the vessels. The blood in the artery directly flows into the vein via fistula. This process can enlarge the vessel and the blood flow, which is beneficial for hemodialysis treatment. When the vein becomes larger, the needles can be easily inserted into the vein.
Fistula Pros and Cons
Once you have a fistula through a surgery, if you protect it well, your fistula can last a long time for you, even several decades. So a fistula lasts longer than other 2 types of accesses. And another advantage is that it is not prone to being infected. Once it matures, it can provide excellent blood flow, which is good news for hemodialysis. Compared with other 2 types of accesses, it is not prone to developing blood clots and become blocked. After the treatment, if the access heals, you can take showers.
An AV fistula needs one to four months to become mature. The time is even longer, up 24 months. So if you can not wait hemodialysis treatment, a temporary method must be considered. And the needles are directly inserted into your vessels to connect to the dialysis machine.
A dialysis fistula is the most popular and effective dialysis access, because it has fewer complications, such as infection, blood clot etc.
