Non-saccular aneurysms: pathogenesis, clinic and methods of treatment (review)

Abstract

In clinical practice, we use the term “fusiform aneurysm” for local expansion of artery. Under this generic term specialists understand heterogeneous arterial pathology, which is very important for diagnosis and choosing the treatment. We conducted an analysis of scientific literature published in 1987–2019, including 63 foreign and 4 Russian sources devoted to pathogenesis and types of non-saccular aneurysms. Among non-saccular aneurysms, dolichoectatic aneurysms are distinguished, rather of genetically or non-atherosclerotic origin and fusiform aneurysm acquired due to dissection processes. Features of mechanisms of their formation, variants of clinical course and methods of treatment are presented.
