Perioperative Venous Thromboembolism: Risk Assessment and Risk-Stratified Prophylaxis for Surgical Patients
In this webinar, Dr. Cassidy will discuss what is known about risk factors, risk assessment, and perioperative venous thromboembolism (VTE) prophylaxis, including extended postoperative prophylaxis. He also will share the outcomes of a standardized program of risk stratification and risk-based VTE prophylaxis regimens.
Background: VTE is considered a preventable cause of morbidity and mortality following surgery. VTE, which includes deep venous thromboses (DVT) and pulmonary emboli (PE), may cause sudden death or long-term sequelae. Patients are at risk for VTE events after surgery due to the associated inflammatory state, endothelial vascular injury, and venous stasis. A variety of other predisposing factors have been identified, each conferring differing degrees of VTE risk. Awareness of these risk factors permits the calculation of a numeric VTE risk score. One method for risk stratification is the Caprini risk assessment.
Prophylaxis for VTE events has been well studied, and current guidelines suggest consideration of both mechanical and pharmacologic prophylaxis. Currently accepted recommendations for prophylaxis are based primarily on the type of surgery with less emphasis placed on individual risk assessment. A more effective prevention strategy may be the use of formal risk calculation, stratification, and risk-based prophylaxis for every surgical patient.
