Definition of Postoperative hemorrhage
Medically reviewed by Min Clinic Staff | Updated: January 2026
Postoperative hemorrhage: Bleeding after a surgical procedure. The hemorrhage may occur immediately after the surgery or be delayed. It need not be restricted to the surgical wound. Common causes of postoperative hemorrhage are from tissues which cannot be entirely prevented from bleeding and depend on blood clotting to stop the hemorrhage, problems in the normal clotting mechanism of blood, and clips or ties around blood vessels becoming loose.
