Perivascular sclerosis, or periarterial sclerosis (lat. sclerōsis periarteriālis) is a pathological process characterized by the proliferation of connective tissue around the walls of arteries and arterioles.
Perivascular sclerosis can be a consequence of various diseases, such as atherosclerosis, diabetes mellitus, rheumatoid arthritis, ankylosing spondylitis and others.
With perivascular sclerosis, normal tissue is replaced by connective tissue. This can lead to disruption of blood supply to organs and tissues, which can cause various symptoms such as joint pain, sensory disturbances, decreased muscle strength, etc.
Treatment for perivascular sclerosis depends on the cause of its occurrence and may include drug therapy, surgery and physical therapy. However, in most cases, treatment is aimed at eliminating the underlying disease that led to the development of perivascular sclerosis.
