Prevention of blood clots increased risk for surgery
Surgery is the most important risk factor for development of venous thrombosis disease, and approx. one-third of all cases seen after surgery. The risk is particularly high after surgery for hip fracture, replacement of the hip joint and the knee surgery. Preventive treatment with blood-thinning agents (LMWH) reduces the incidence of deep-vein thrombosis, pulmonary embolism and death.
Use of the site anesthesia (regional anesthesia) instead of general anesthesia, gentle surgery and rapid mobilization of patients, are factors that contribute to reduce the risk of blood clots. Along with the prophylactic use of agents to prevent blood clots, this has contributed to reduce the incidence of thrombosis disease after surgery. However, still, this complication remains a significant problem.
Some people are more susceptible to blood clots after surgery than others. It applies to people who have had blood clots before, who have an inherited increased risk of blood clots family illness, obesity, age over 40 years, with cancer, people with high blood count (polycythemia), women using birth control pills or estrogen, and those where the procedure is lengthy and involves prolonged immobilization.
