... wall stress are shown in Fig. 2 . Table 1 lists all observed and computed metrics, and Table 2 lists all relevant p- values for statistical comparison across testing protocols and regions. Fig. 1 Dose–response data collected for DTA (black) and IAA (gray) using three different classes...

... computed value agrees with the average wall stress of 0.18 ± 0.01 MPa calculated from the experiments. All these input parameters were the average values estimated from experiments. The hypertension-induced remodeling progress was initiated by applying an elevated pressure of 172 mm Hg. The remodeling...

... the strength of the wall. Peak wall stress computations appear to give a more accurate rupture risk assessment than AAA diameter, which is currently used for a diagnose. Despite the numerous studies utilizing patient-specific wall stress modeling of AAAs, none investigated the effect of wall calcifications...

... to be modulated by the overall wall stress. Such G&R depends on the way the new collagen is deposited, that is, how the collagen is deposited within a stressed lesion and its alignment. Driessen et al. ( 5 ) suggested that arterial collagen tends to align with a preferred...

..., the transient three-dimensional interactions between luminal blood flow, stent-graft wall, leakage flow, and AAA wall are computationally simulated. For different type I endoleak scenarios and inlet pressure wave forms, the impact of type I endoleaks on cavity pressure, wall stress, and stent-graft migration...

... dangerous wall stress levels and aneurysm rupture, a transient 3-D stented abdominal aortic aneurysm model and a coupled fluid-structure interaction solver were employed. Simulation results indicate that, even without the presence of endoleaks (blood flowing into the cavity), elevated sac pressure can occur...
