Overview

Venous thromboembolism (VTE) consists of deep vein thrombosis (DVT), pulmonary embolism (PE), or both. The risk factors for VTE are a constellation of predisposing conditions which stem from the three principles of Virchow's triad: stasis of the blood flow, damage to the vascular endothelial cells, and hypercoagulability. The risk factors for VTE can be categorized as temporary, modifiable and non-modifiable. Venous thrombosis also shares risk factors with cardiac thrombosis, such as obesity, hypertension and smoking.
