Abstract


An aneurysm is a localized, blood-filled balloon-like bulge in the wall of a blood vessel. It is a cardiovascular health disease that occurs when the blood vessel becomes weak. Aneurysms can occur in any blood vessel commonly seen in artery of circle of Willis in the brain, aortic aneurysm affecting the thoracic aorta and abdominal aortic aneurysm (AAA). In this paper, an attempt has been taken to review different techniques and methods for the assessment of aneurysm and the relevant decision to be taken to combat the risk of rupture. There is limited number of experimental studies due to incorporation of actual biological environment along with patient specific material properties. While, the numerical techniques like computational fluid dynamics (CFD) has lead to revolution in assessing relationship between cardiovascular disease and hemodynamic factors. The effects of the hemodynamic factors and wall mechanics on the initiation and progression of the disease aneurysm have been discussed in this review. A special focus is given on the trend of development of non invasive techniques in assessing the risk of rupture. Finally, this review paper discusses some methods for better understanding of the occurrence and progression of the disease aneurysm leading to the rupture of the artery.
