Arterial walls stiffen with age. The most consistent and well-reported changes are luminal enlargement with wall thickening and a reduction of elastic properties at the level of large elastic arteries. Longstanding arterial pulsation in the central artery causes elastin fiber fatigue and fracture. Increased vascular calcification and endothelial dysfunction are ...

Hemodynamic insult has been speculated to be a key factor in intracranial aneurysm formation; however, it is unclear whether a sustained insult is necessary. The authors examined whether aneurysmal degradation would continue despite the normalization of wall shear stress (WSS) by adaptive outward vascular remodeling. Twenty-five rabbits underwent either sham ...
