Appointment Helpline
An arteriovenous condition affects a vein or an artery. Before starting regular hemodialysis treatments, you need AV fistulas or AV grafts. AV fistulas connect selected arteries and veins directly for long-term dialysis. An AV graft joins an artery and vein indirectly through a tube and graft.
The doctors use an external machine called a dialyser to treat kidney disease through dialysis. Dialysis pumps blood back into your body after removing wastes and extra fluids. The dialyser requires a large amount of hemodialysis effectively. Blood flows continuously and smoothly during dialysis due to AV fistulas and AV grafts. Book an appointment to have the best treatment.
Which is better, an AV fistula or an AV graft?
Your vein specialist will thoroughly examine you and your blood vessels before making a recommendation. A dialysis graft and a fistula are both effective access options, which Manipal Hospital provides along with your nephrologist. Consider the following points:
Effectiveness: The doctors administer hemodialysis with an arteriovenous fistula, which can last many years compared to an AV graft.
Risks: With the help of an experienced vein specialist at Manipal Hospitals, you will significantly reduce the risk of infection and blood clots associated with the AV graft.
Type of access: AV fistulas do not require artificial materials, unlike AV grafts, which require synthetic tubes.
Blood flow rate: An AV fistula reduces dialysis times and increases the effectiveness of dialysis.
Solution for problem veins: The AV graft is an alternative to the AV fistula procedure for smaller and weaker veins.
Time: AV grafts are ready for use within two to four weeks, whereas AV fistulas take months to prepare.
When deciding between AV fistulas and AV grafts for your vascular access, doctors consider these factors and your current needs. You will choose the correct procedure depending on your needs and your decision. Visit our vascular surgery hospital in Bangalore for the best treatment.
Procedure of AV Fistula
It is a surgical procedure used to connect an artery and a vein directly through an arteriovenous fistula. The blood flow and pressure in the vein must be higher for adequate hemodialysis treatment. The doctors can use AV fistula for long-term dialysis. Here are the steps involved:
Vessel mapping: The doctor uses imaging tests to view your arteries and veins.
AV fistula preparations: Your vascular specialist sets the access site before administering the local anaesthesia. The vascular specialist makes an incision to access the chosen arteries and veins.
AV fistula creation: During an AV fistula, an artery is surgically connected to a vein, allowing blood to flow from the street to the vein.
Recovery: Before starting hemodialysis treatments, the AV fistula may need to heal for a few months.
Hemodialysis treatments are made possible by vascular access. An AV fistula allows you to manage end-stage renal disease more effectively when appropriately placed. During the waiting period for an organ donation, hemodialysis treatments keep you alive.
AV Graft Procedure
Vascular access procedures, such as arteriovenous grafts, use synthetic tubes to connect arteries and veins. Patients with small or thin veins or needing dialysis more urgently should consider this outpatient procedure. Following are the AV grafts procedure:
An assessment of the health of the veins or arteries
Site selection for access
A local anaesthetic is applied to the access site to prepare it for access.
AV graft placement involves connecting one end of the grafted tube to an artery, then looping the graft under the skin and securing it to a vein under the incision.
An artery's blood flows into the graft, followed by a vein's blood.
After healing, hemodialysis begins.
A vascular surgeon must carefully assess the veins of your body before deciding between dialysis shunts and fistulas. At Manipal Hospital Vascular Surgery Center, the team carries out imaging tests with the latest medical equipment to choose between AV shunts and fistulas.
