Challenges of long‐term vascular access in pediatric hemodialysis: Recommendations for practitioners

Abstract Kidney transplantation is the preferred treatment of end‐stage renal disease in children. However, time to transplant varies, making a well‐functioning long‐term vascular access essential for performing hemodialysis efficiently and without disruption until a kidney becomes available. However, establishing long‐term vascular access in pediatric patients can present distinct challenges due to this population's unique characteristics, such as smaller body size and lower‐diameter blood vessels. There are three main pediatric long‐term vascular access options, which include central venous catheters (CVC), arteriovenous fistula (AVF), and arteriovenous graft (AVG). CVC are currently the most widely used modality, although various studies and guidelines recommend AVF or AVG as the preferred option. Although AVF should be used whenever possible, it is crucial that clinicians consider factors such as patient size, physical exam findings, comorbidities, predicted duration of treatment to decide on the most optimal long‐term vascular access modality. This article reviews the three long‐term vascular access methods in children and the benefits and complications of each.
