Blood flow through a stenosed artery and its constrained bypass graft design

Abstract

Because arteries transport blood that is rich in nutrients and oxygen to cells, its narrowing or obstruction can affect how well tissues are nourished. The hemodynamic patterns of these vessels have a significant impact on their structural stability and long-term patency. Bypass grafts are used to circumvent stenotic arteries. Here, blood flow through a stenosed coronary bypass with size constraints is studied. The effect of graft-vessel(host) diameter ratio, degree of stenosis, and blood flow ranging from resting to active conditions is examined.
