  • Research summary

    Formation of an arteriovenous fistula (AVF) is a common procedure for patients requiring haemodialysis, or external cleaning of the blood, due to kidney failure. Surgically connecting an artery and vein in the arm creates a high flow access to support cleaning of the blood. For this to happen, AVFs require a period known as maturation. However, some AVFs fail to mature on their own. In some instances, another procedure may be performed to improve the chances of it maturing. This is known as balloon assisted maturation (BAM). Not all BAM procedures successfully result in maturation, therefore this study is concerned with looking for changes after the procedure which may allow for prediction of which AVFs will, or will not, mature. Duplex ultrasound (DUS) is a safe and readily available form of imaging that enables assessment of blood flow, and is ideal for serial scans during the crucial maturation phase. In addition to blood flow changes, the study will analyse changes in inflammatory biomarkers in the blood to see how this affects the success of BAM and maturation.
