This study introduces a numerical model for platelet plug formation, revealing that plug deformability is crucial for its growth during blood flow simulations.
Area of Science:
- Biomedical Engineering
- Computational Fluid Dynamics
- Solid Mechanics
Background:
- Platelet plugs are critical in haemostasis and thrombosis.
- Understanding platelet plug dynamics requires integrated modelling approaches.
Purpose of the Study:
- To develop and apply a numerical framework for modelling platelet plug dynamics.
- To investigate the influence of plug deformability on plug growth and haemodynamics.
Main Methods:
- A numerical framework combining biochemical, solid mechanics (neo-Hookean elastic solid, updated Lagrangian approach), and fluid-structure interaction models.
- Simulations applied to various haemodynamic conditions and plug shear moduli.
Main Results:
- The study presents results on plug growth, shape, size, and stress distribution.
- Simulations demonstrate the interplay between blood flow and plug mechanics.
Conclusions:
- Platelet plug deformability is essential for its growth.
- The developed framework provides insights into the biomechanics of platelet plug formation.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
