ASH evidence-based guidelines: what is the role of inferior vena cava filters in the perioperative prevention of venous thromboembolism in bariatric surgery patients?

A 38-year-old morbidly obese male (BMI > 50 kg/m(2)) presents for an elective gastric bypass surgery. He has no personal or family history of venous thromboembolism or hypercoaguability. You are asked by his primary team whether he should receive a retrievable inferior vena cava filter preoperatively for venous thromboembolism prophylaxis.
