Antti Siika at the Vascular Surgery research group, Department of Molecular Medicine and Surgery, will defend his thesis "Biomechanical and Morphological Aspects of Abdominal Aortic Aneurysm Growth and Rupture" on April 28th, 2023.

Main Supervisor is Joy Roy.

What's the main focus of your thesis?

The thesis investigates abdominal aortic aneurysms, and charts aneurysm progression over time, as well as factors related the risk of rupture. We have used computed tomography imaging in combination with computerized methods for biomechanical simulation.

Which are the most important results?

The most important results show that biomechanical variables may be used to predict the rupture of abdominal aortic aneurysms. Additionally, we have described AAA evolution over time.

How can this new knowledge contribute to the improvement of people's health?

The dissertation develops the understanding of aneurysm disease by expanding the current paradigm where only the maximum aneurysm diameter is used for monitoring disease progression.

What are your future ambitions?

To continue research in the field of vascular and aortic disease.
