Abstract

Morbid obesity is a major risk factor for the development of deep venous thrombosis (DVT) and pulmonary embolism (PE). Thromboembolic complications are the most common cause of death in bariatric surgery and contribute significantly to postoperative morbidity (1). A study of risk factors for venous thromboembolism in hospitalized patients demonstrated an association with age over 40 years, obesity, and major surgery (2). The increased risk in the morbidly obese is attributable to a sedentary lifestyle, increased abdominal pressure, and the excessive weight resting on the inferior vena cava drainage. Additional risk factors include prior history of DVT or PE, immobility, pregnancy, oral contraceptive use, smoking, hypercoagulable states, malignancy, and trauma (Table 26-1). Although they are usually diagnosed as postoperative complications, DVT and PE may also occur in nonhospitalized patients. Studies of risk factors for thromboembolism in the general population have demonstrated an association with obesity, suggesting that morbid obesity is an independent risk factor for DVT and PE (3,4).
