- Stasis refers to a stoppage or slowdown in the flow of blood (or other body fluid such as lymph). A stasis ulcer is an ulcer (a crater) that develops in an area in which the circulation is sluggish and the venous return (the return of venous blood toward the heart) is poor. A common location for stasis ulcers is on the ankle. "Stasis" is a Greek word meaning "the posture for standing" and is derived from the Greek "histemi" meaning "to make stand still."
