Interventions

PROCEDURECreation of an arteriovenous fistula

Patients will undergo the surgical procedure to create an arteriovenous fistula and will be discharged the same day (outpatient care, or an overnight stay in hospital if they live a long way from the hospital, have multiple pathologies or are socially isolated). An arteriovenous fistula is created under local or general anaesthetic. On the day of the operation, the type of arteriovenous fistula created, the side of the arteriovenous fistula, the location of the arteriovenous fistula and the patency of the arteriovenous fistula will be collected.
