The blockage of a fistula for dialysis is usually considered to be related to factors such as thrombosis of the fistula, stenosis of the fistula, reduction of effective circulating blood volume (e.g., fever, gastrointestinal bleeding, etc.), and inappropriate use of the fistula. Anticoagulants, balloon dilatation, arteriovenous fistula reconstruction, switching to peritoneal dialysis or hemodialysis catheter dialysis treatment can be used. 1. Use of anticoagulants: If the fistula is blocked due to blood clotting caused by hypercoagulation of blood during dialysis, anticoagulants (e.g., sodium citrate) can be used to remove the blood clot so that the fistula can usually be opened again. 2. Balloon dilatation: the fistula may be blocked because of the narrowing of the blood vessels at the endocardial fistula, balloon dilatation to relieve the stenosis, the blockage will generally be lifted. 3. Arteriovenous fistula reconstruction, switch to peritoneal dialysis or hemodialysis catheter dialysis treatment: If the original fistula is blocked, after evaluation can no longer be used, according to the condition of the arteriovenous fistula reconstruction, peritoneal dialysis or hemodialysis catheter dialysis treatment, inform the patient of the advantages and disadvantages of the various options, so that they can choose. Fistula blocked specific selection of which method, need to go to the regular hospital, and the doctor detailed communication, to develop the most appropriate treatment program.
