Aortic Dissection And The Importance Of Virtual Surgery

Originating from the left ventricle of the heart, the aorta, the largest artery in the human body, extends downward to provide oxygenated blood to the entire body. It holds a pivotal role in sustaining systemic circulation and faces constant exposure to elevated blood pressure, given its central position in the circulatory system. Aortic dissection is an extremely grave condition that results in the separation of the inner layer of the aortic wall and subsequent fragmentation. In the initial two weeks, the untreated dissection carries a mortality rate of 75%. The hemodynamic characteristics of blood flow within the newly formed false lumen, and its dominance over the true lumen, significantly influence both the surgical outcome and the patient's life. Utilizing virtual operations and numerical methods to solve physical quantity fields obtained from modeling provides a clear insight into how the surgery impacts the flow through the branches affected by dissection. The patient discussed in this study experienced a type I aortic dissection according to DeBakey classification. The results are presented for the case both before and after the virtual surgery.
