The cause of thrombophlebitis is a blood clot. Blood clots can be caused by many different things — namely anything that causes your blood not to circulate properly. It's possible a blood clot that causes thrombophlebitis could be caused by:

  • An injury to a vein
  • An inherited blood-clotting disorder
  • Being immobile for long periods of time, such as during a hospital stay
