Abstract
Abdominal aortic aneurysms affect 0.2% of the population and are closely associated
with intraluminal thromboses (ILTs) that develop in the sac. Advanced imaging and
treatment techniques are available, however there is room for improvement in the
methods used to predict the outcome or necessity of surgical intervention. For a
computational model to be useful in this clinical setting, it would need to incorporate
relevant patient-specific data and prioritise simplicity and speed over exhaustive detail.
This paper presents the details of such a model, for abdominal aortic aneurysms,
particularly in the simplification of the coagulation biochemistry. Explicit modelling of
the coagulation cascade is replaced with a patient-specific thrombin generation curve.
This curve is defined by three values obtained from a blood test. Another key feature
is the thrombosis growth model, which incorporates conversion of fibrinogen to fibrin,
variation between clot core and shell, and mechanical lysis. The model generates ILTs
with morphologies visually similar to those typically found in the body, however more
work is required to refine and validate the model.
