Anemia Local

What is **local anemia**? In the early nineteenth century, Adalbert Collitz described arteriosclerosis, a condition in which the arteries become narrowed. English researchers observed similar disturbances of the venous bed. This disease was called "ischemia" ("blood stoppage"). Later, German scientists identified venous lesions with arrest of capillary circulation and clinically detectable changes (“mesocoicosis of arterioles” - Arner, Leverkühne, Veldeke). Finally, already in the 80s, the fact of the existence of local changes in arterial and venous vessels in people with certain chronic diseases was established. But only in the first decades of the 20th century the concept of “angiodysplasia” was identified. In our country, an important link in the origin of local cardiovascular diseases was studied - atherosclerosis of the arterial vessels of the heart and brain (P.F. Heart disease. Moscow, 1972; P.A. Stalnaya. Dysplastic changes in the coronary arteries of the heart. Monograph, Moscow, 2011).

The peculiarity of these local changes in the venous and arterial vessels is their prevalence (often found), focal localization, non-regenerative significance, significant detection frequency (may be one of the causes of cardiovascular mortality). In the classic version of angiodysplasia, the affected vessels are formed from a single helix, located in groups or individually. They are usually long, have wide openings, twisted under the weight of soft tissues, collapsed, are affected by the inflammatory process, are easily irritated by all external causes, and form various branches.
