Research Advances of Risk Prediction Methods for Acute Pulmonary Embolism in Patients with Lower Extremities Deep Venous Thrombosis

Abstract

Lower extremity deep venous thrombosis (LEDVT) is a disease of venous return disorder caused by abnormal blood agglutination in lower extremity deep vein. In recent years, the incidence of DVT is increasing gradually and the age of onset tends to be younger. One of the primary hazards associated with LEDVT is pulmonary embolism (PE) resulting from thrombus dislodgement. Once pulmonary embolism occurs, the prognosis is frequently poor; in severe cases, it can pose a significant threat to the patient’s life. Consequently, early detection and prompt diagnosis of pulmonary embolism are crucial for enhancing patient outcomes and mitigating the risk of mortality. There is sound evidence supporting the use of several methods to enhance the diagnosis and predict the risk of PE. Therefore, the review aims to provide a comprehensive overview of the literature concerning diagnostic methods for PE.
