ABSTRACT: Despite advances in prophylaxis, diagnosis, and treatment, venous thromboembolism remains a leading cause of disability and death in postoperative, hospitalized patients 1 2 3.Venous thromboembolism most commonly occurs in the form of a deep vein thrombosis or pulmonary embolism. Submassive pulmonary embolism or “intermediate-risk” PE is characterized by normal blood pressure with evidence of right ventricular dysfunction (RV dilation on echocardiogram; elevation of BNP or N-terminal pro-BNP; EKG evidence of new right bundle branch block, anteroseptal ST elevation, depression, or T-wave inversion) or myocardial necrosis (elevation of troponin). Prevention of Deep Vein Thrombosis & Pulmonary Embolism. Fatal recurrent pulmonary embolism occurs in less than 5 percent of patients. Pulmonary embolism usually arises from a thrombus that originates in the deep venous system of the lower extremities; however, it rarely also originates in the pelvic, renal, upper extremity veins, or the right heart chambers (see the image below). Massive pulmonary embolism or “high-risk” PE is characterized by sustained hypotension (systolic BP < 90 mmHg or requiring pressors) that is not due to another cause. The prevalence of pulmonary embolism increases thirty-fold when individuals in their forties (20/100,000 population) are compared with individuals in their seventies and eighties (300/100,000 population). 1-ranked heart program in the United States.
