A 44-year-old Indian woman presents to the emergency room with complaints of right leg soreness and fatigue. The pain began two days ago after a long flight from South Africa. Her medical history includes diabetes, and she is recovering from a hysterectomy performed 10 days ago. Due to a family emergency, she interrupted her post-surgery rest to travel. She smokes one pack of cigarettes daily. Physical Examination: Obese, afebrile, and anxious. Obvious swelling in the right lower leg, with a calf circumference 4 cm larger than the left leg. Collateral superficial veins are present. Entire leg swollen with pitting edema. Tenderness of the calf increases with gentle squeezing. Pain worsens with dorsiflexion of the right foot with the knee extended (positive Homan’s sign). No redness of the leg. The patient was admitted, and a lower extremity ultrasound confirmed the diagnosis of deep vein thrombosis (DVT). Which of the following does NOT increase the likelihood of deep venous thrombosis in this patient?
