Doppler Ultrasonography in Planning Arteriovenous Fistula for Haemodialysis with Follow-up for Maturity and Complications- A Cohort Study

Introduction: Patients having End Stage Renal Disease (ESRD) require kidney replacement therapy for survival. As transplantation is expensive, haemodialysis using an Arteriovenous Fistula (AVF) the preferred mode of management. Preoperative assessment blood vessels Doppler Ultrasonography (DUS) in creation efficient AVF. Aim: To use DUS evaluation and mapping vessels, selection AVF construction, time taken fistula maturation, primary patency rate, vascular changes major co-morbidities complications on follow-up. Materials Methods: An observational cohort study 100 patients requiring was undertaken between January 2015 to November 2016 at Department Radiodiagnosis Imaging, PES Institute Medical sciences Research, Kuppam, Andhra Pradesh, India. Pre-operative duplex performed know diameter, caliber, distensibility veins flow velocity arteries. Postoperative follow-up done fourth sixth week early detection management complications. Results: The included total (64 men 36 women, mean age 40±15.4 years) aged 16 65 years. Following mapping, Brachio- Cephalic (BCF) constructed 48 Radio- (RCF) 52 patients. A diameter 2.1 mm cephalic vein forearm 2.6 arm adequate construction. Overall maturity rate 75% maturation 4 weeks BCF, 6 RCF one year 80%. Complications were noted 30%, thrombosis, haematoma, stenosis, pseudoaneurysm so on. Conclusion: economical investigation with exceptional ability visualise features aids planning reliable Systematic postoperative surveillance reduces risk failure due
