Summary
Phlebomalacia refers to the softening or weakening of a vein wall as a specific instance of angiomalacia. This condition can stem from various pathological processes such as necrosis, degeneration, inflammation, or atrophy, and has been considered by some theories as a precursor to phlebosclerosis and phlebectasia.
Encyclopedia entry (1928–1936)
PHLEBOMALACIA, softening, weakening of the wall of a vein. Phlebomalacia is a particular case of angiomalacia in general. At its base may lie the most varied pathological processes leading to an alteration of the physical properties of the vein wall. Phlebomalacia may result from necrosis, degeneration, inflammation, atrophy, etc. Among the theories explaining the development of phlebosclerosis and phlebectasia, there exists Thoma's theory, which interprets their origin as the result of preceding phlebomalacia, possibly of a vasomotor nature, i.e., the same point of view as regarding the origin of atherosclerosis (see Arteriosclerosis).
