Recurrence

Relapse, reappearance of a disease. In the case of varicose veins, there is no treatment for the underlying connective tissue weakness, so the reappearance of such veins, for example, after surgery, is due to the development of new varicose veins. Furthermore, if treatment is incomplete, veins that were initially closed open up again, disconnected veins sometimes grow again, or a collateral (by-pass) circulation develops. In principle, varicose veins are a progressive disease and cannot be completely cured by any known treatment. So there is always the possibility of new varicose veins developing.
