Fluid dynamic characterization of a novel branching anastomosis design

Abstract: Geometric characteristics of a vascular anastomosis can have important biomechanical impacts, particularly in the hemodynamic context of wall shear stress (WSS). In this study, we propose a new branching anastomosis design, the Hybrid anastomosis, to connect a donor vessel to two recipient vessels. The central obstruction characteristic of the traditional Figure 8 anastomosis is mitigated by creating a recessed lumen at the bifurcation. Chicken vessels were used to create and test three Figure 8 and three Hybr… Show more

“…Through fluid simulations, many perturbations of device designs or treatment options can be simulated in silico before either high cost surgery or further in vitro experiments. CFD simulations have been used to evaluate the design of Y-grafts for Fontan operations [8385], anastomosis design [86], stents [87, 88], and flow-diverters [89, 90]. To enable predictive treatment planning, the mesh representing the vascular geometry is modified to represent different potential surgical outcomes.…”
