What are the Common Histological Findings in Aging Vertebral Arteries?

With aging, vertebral arteries may exhibit several histological changes. There is often increased deposition of collagen in the tunica media and adventitia, leading to decreased elasticity. Additionally, there may be a thickening of the tunica intima due to the accumulation of lipids and calcification, contributing to atherosclerosis. These changes can compromise blood flow, highlighting the importance of histological studies in understanding age-related vascular diseases.

In conclusion, the histological study of vertebral arteries provides valuable insights into their function, the impact of aging, and various pathologies that can affect them. By examining these arteries at the microscopic level, researchers and clinicians can develop better strategies for diagnosis, prevention, and treatment of vascular diseases affecting the central nervous system.
