Current project: AVF Failure Prediction Model

Arteriovenous fistula (AVF) is a necessary surgically modified vascular structure to allow chronic kidney disease (CKD) patients to undergo hemodialysis. Unfortunately, complications often arise in an AVF causing it to not provide adequate blood flow to function normally.


My research focuses on methods to predict arteriovenous fistula (AVF) failure based on the combination of existing patient’s data and computational modelling. I work closely with vascular surgeons in the Prince of Wales Hospital to study the condition of an AVF by scanning patients with an ultrasound imaging system. With patients’ data, I aim to develop an indicator for AVF failure, by simulating close to real world condition of the AVF via computational modelling. This research aims to contribute to the on-going efforts to reduce AVF failure, and to improve the quality of life of CKD patient by effectively aid surgical planning and outcome.
