How can I prepare for an arteriovenous (AV) fistula formation?

HD vascular access 2


If you are taking anticoagulant medication to thin your blood (for example warfarin, or injections such as heparin, dalteparin or enoxaparin), please tell the doctor/nurse who is responsible for your procedure. They will tell you when to stop these medication before the procedure and when it safe to restart them after procedure.

Please also tell the doctor or nurse if you are on antiplatelet medication (such as aspirin, clopidogrel or dipyridamol). They will advice you whether you should continue with this treatment or stop it temporarily before your procedure.

If you are having a general anaestheticĀ  you will need to fast (not eat or drink anything) for six hours before your operation. However, you are allowed to drink still water up to two hours before your operation. You will be admitted on the morning of your operation and you will usually need to stay in hospital overnight.

If you have your operation under local anasthaetic, you can eat and drink normally. You will be admitted on the morning of your operation and should be able to go home the same day.
