AneurysmAneurysm An aneurysm is a distention of an artery brought by a weakening/ destruction of the arterial wall. In response to changes in the biomechanical environment, aortic cells and extracellular matrix modulate their structure and functions to increase aortic wall strength and meet the hemodynamic demand. Aortic aneurysms occur when a weak part of the aorta expands like a balloon, forming a blood-filled sac.Mostly, aneurysms cause no symptoms, but they can be life-threatening if they become too large and rupture, or burst. aneurysm, widening of an artery that develops from a weakness or destruction of the medial layer of the blood vessel. Most patients with IMH have Stanford type B (50% to 85%). Bleeding may be tamponaded by surrounding structures, thus preventing exsanguination and death.
