Computational study of stented and wrapped aortic aneurysms.

Area of Science:

• Biomedical Engineering
• Cardiovascular Research
• Computational Fluid Dynamics

Background:

• Aortic aneurysm involves aortic enlargement, with dissection as a risk factor.
• Aneurysm wrapping and stent placement are established treatment methods.
• Understanding the biomechanical impact of these treatments is crucial for patient outcomes.

Purpose of the Study:
