What injuries can cause blood clots?

Thoracic Surgery (Cardiothoracic Vascular)
It’s easier to ask what types of injuries don’t cause clots! Any type of injuries can promote increased risk of blood clots. If you have an injury, you usually have swelling in the tissue that’s damaged, and there’s potentially bleeding. That constricts the vessels traveling through the tissues, which can promote clots inside the vessels.

Some injuries may lead to impaired movement, decreasing circulation throughout the body and increasing the likelihood that blood may clot.

Accidents and injuries that increase deep vein thrombosis (DVT) risk:
  • serious falls
  • broken bones, especially in the pelvic area or legs
  • broken bones with a limb in a plaster cast
  • spinal cord injury
