Washington D.C. [USA] Aug 25 (ANI): Turns out aneurysm occurs anywhere throughout the circulatory system but most commonly develop along the aorta and in blood vessels of the brain. Expansive arterial remodeling (EAR) comprises a genetically programmed biological response designed to restore homeostatic levels of arterial wall stress after an increase in vessel flow load occurs. The magnitude and rate of EAR reactions relative to local hemodynamic stress fields and the tensile strength of vascular tissue determine whether the process will result in a stable mural structure (adaptive remodeling) or an unstable mural structure that progresses to form an aneurysm
