Predictors for failure to mature of autogenous arteriovenous fistulae: Alor Setar experience.

The reported rates of Primary Fistula Failure (fistula fail to mature) varies from 8% to 53%. Immature fistulae will lead to prolonged dependence on dialysis catheters. This phenomenon is well known to be associated with the risk of infective complications, central venous thrombosis or stenosis and patients’ inconvenience. Numerous studies have reported the predictors of successful fistulae, but are varied in their design, definitions, end points and clinical factors considered 2,3 Preoperative imaging also has been proposed, but their widespread use is generally limited in most of the centres. Knowing the risk factors for failure will help the surgeon to take the necessary precautions and preventive measures more effectively. The information may help to stratify the patients into various risk groups based on their likelihood to develop fistula failure. Thus, the main objective of this study was to identify clinical risk factors that are related to Failure to Mature (FTM) of autogenous AVF.
