On the day 2nd of October in the Institute of Turbomachinery dr inż. Daniel Jodko presented a seminar: "Fluid-structure interaction simulations in the analysis of development of anteriovenous fistula. A short story about pressure… and never giving up".
Arteriovenous fistula (AVF) is an abnormal connection or passageway between an artery and a vein utilized in patients undergoing hemodialysis. AVF is created by surgically connecting an artery and a vein, which leads to non-physiological, locally disturbed blood flow. Numerical methods can create flow analysis with high spatiotemporal resolution, for subsidiary diagnostic imaging.
During the seminar dr Jodko explained our collaboration with University of New South Wales (UNSW) which designed a technique for reconstruction of anatomic structures through ultrasonographic examination. The technique allows safe examinations in vivo and follow-up tests. It also allowed an analysis of the fistula’s development to be made – a biological reconstruction that lasted from its creation to the beginning of hemodialysis. The fluid-structure interaction technique (FSI) implemented supplemented UNSW’s methodology, benefiting both sides of the collaboration. Numerical simulations also supplemented experimental research. The project has led to:
- Evaluation of medical value of the development models made before
- Analysis of factors that affect vulnerability of vascular walls during FSI simulations
- Analysis of quality and volume of the flow during fistula’s development and later
- The evaluation of the blood’s tenacity on the results of computer simulations of the flow and the various results obtained
We give our thanks to dr inż. Jodko, and everyone who attended the seminar, and we encourage our students and employees to join the seminars we will organize in the future.
