Introduction: Chronic kidney disease (CKD) is increasingly being recognized as a global public health problem. The focus in CKD has changed from treating a terminally ill patient, to dealing with a person who has a manageable chronic disease that requires long term care. Hemodialysis (HD) is the most commonly used method of dialysis. Arteriovenous fistulas (AVF) are considered the gold standard for hemodialysis access based on their superior patency, low complication rates, improved adequacy, lower cost to the healthcare system and decreased risk of patient mortality. Aim: to identify the risk factors for failure of Brachio-cephalic arteriovenous fistula (BC AVF). Methodology: This was a single centre, observational longitudinal study done on 98 patients with Brachio-cephalic arterio-venous fistula (BC-AVF). Results: We observed that majority patients were between 51-70 years of age. Two fistulas that failed during the 15 days follow up were in age group >70 years, 3 fistulas that failed at 30days follow up were in age group between 51-70 years.
