A Prospective Study Comparing the Effect of Rivaroxaban vs. Enoxaparin Given as a Prophylaxis for Deep Venous Thrombosis in Patients Undergoing Bariatric Surgery

Abstract

O besity is a risk factor for deep vein thrombosis (DVT) and venous thromboembolism (VTE). VTE is the most common cause of mortality in patients undergoing bariatric surgery. Most of the literature is based on European & American patients and specific guidelines for Egyptians do not exist. Venous thrombosis, comprising deep vein thrombosis (DVT) and pulmonary embolism (PE), occurs with an incidence of approximately 1 per 1000 annually in adult populations. Rates are slightly higher in men than women. Venous thrombosis is a disease of aging, with a rate rising rapidly after age 45 years, and approaching 5–6 per 1000 annually by age 80. There are also differences in incidence of diagnosed venous thrombosis among ethnic groups. An understanding of the risk factors for venous thrombosis is necessary in order to maximize the prevention of this disease in high risk groups of patients. Some of these risk factors are modifiable, while others, like aging and genetic predispositions, are not.
