Which is NOT a major perioperative venous thromboembolism risk factor?

• A. Regular exercise
• B. Immobilization
• C. Obesity
• D. Prior VTE

Answer: (A)

Regular exercise is not a major risk factor for perioperative venous thromboembolism; in fact, it tends to protect against it by enhancing venous return through the calf muscle pump and reducing venous stasis after surgery. Immobilization, on the other hand, dramatically increases risk because lack of movement slows blood flow in the legs. When muscles aren’t contracting to help push blood upward, blood can pool in the venous system, creating an environment prone to clot formation during the perioperative period. Obesity contributes to risk as well. Excess body weight raises intra-abdominal pressure, promotes a pro-inflammatory state, and often accompanies decreased mobility, all of which promote venous stasis and thrombosis after surgery. A history of prior VTE signals an underlying tendency to form clots and strongly elevates perioperative risk; prior events indicate a predisposition that can be exacerbated by surgical stress and immobilization. So, Regular exercise is not a major perioperative VTE risk factor, whereas immobilization, obesity, and prior VTE are.
