What is a collapsed vein?

Venous collapse can occur in association with several potentially-connected phenomena, including direct venous trauma from needle insertion (especially blunt needles), venous sclerosis (hardening or scarring of blood vessel lining) resulting from repeated instances of such trauma and associated inflammation, exposure to irritants in the injected solution, as well as acute venous thrombosis (i.e., clot formation) resulting from acute or chronic vascular inflammation or exposure to foreign particles, micro-organisms, etc.
