Figure 1. This figure illustrates the pathophysiological link between OSA and VTE.

Figure 1

OSA is associated with blood hypercoagulability, venous stasis, and endothelial dysfunction. These three factors contribute to Virchow’s triad and subsequent VTE/DVT/PE formation. The common risk factors between OSA and VTE are also shown.

OSA: obstructive sleep apnea; VTE: venous thromboembolism; DVT: deep vein thrombosis; PE: pulmonary embolism.
