What Is an Arteriovenous Graft?

Arteriovenous fistula is to artificially establish a short circuit between arteriovenous using vascular surgery technology to provide long-term and effective vascular access for extracorporeal circulation for hemodialysis. Direct anastomosis of the distal radial forearm and cephalic vein is the preferred long-term vascular access for dialysis patients. We call it the "standard internal fistula" or "primary vascular access"; sometimes, there are no suitable autologous blood vessels on both forearms It can be used for anastomosis, using alternative blood vessels to establish grafted intravascular fistula, also known as "secondary vascular access". Transplanted intravascular fistula is the use of other blood vessels "bypass" to establish vascular access between arteriovenous veins that are relatively far apart. The blood vessels commonly used for transplantation are mainly autologous blood vessels and artificial blood vessels.

Arteriovenous fistula is to artificially establish a short circuit between arteriovenous using vascular surgery technology to provide long-term and effective extracorporeal circulation for hemodialysis.

There are some common complications after arteriovenous fistulas that deserve the attention of doctors and patients.

Healthy and unobstructed vascular channels are the basic conditions for hemodialysis to be effective in dialysis and long-term survival, to protect the arteriovenous fistula (AVF) in the body, and to extend its service life is to extend the life of the patient. The fistula is the lifeblood of the patient. Therefore, careful care of AVF, proper use and active prevention of its complications are the work that every caregiver should do carefully.

1 Causes and preventive measures of thrombosis

1.1 The causes of early thrombosis are as follows:

(1) Mostly related to the surgical situation;

(2) Poor vascular conditions such as vascular sclerosis,

Patients should be informed about the importance of cooperating to protect AVF:

(1) Keep the arm clean before dialysis. Avoid contact with water and excessive load on the arm after dialysis to avoid infection and bleeding.

(2) The sleeves should be loose, and the arm on the fistula side should not be compressed.

(3) Self-test for fistula anastomosis for tremor. At least 2 times a day, if fistula pain and tremor disappear, come to hospital for treatment.

(4) Those with hemangiomas can be protected with elastic bandages to avoid puncture.
