Rationale
The integration adds two important modern nuances to the traditional understanding of thromboembolic disease. First, it provides a specific physiological mechanism (hypoxia) for how stasis triggers the thrombotic cascade. Second, it introduces the clinically significant concept that not all PE is embolic, particularly in trauma settings, which has implications for how surgeons view the relationship between DVT and PE.

Content Changes
Virchow's triad — endothelial injury, venous stasis, and hypercoagulability — remains the conceptual framework (Rutherford 2018). Recent evidence suggests that venous stasis may lead to DVT through venous valve hypoxia, which triggers a pro-thrombotic microenvironment even in the absence of overt endothelial denudation (Shaydakov 2024).
- Acquired risks: trauma, surgery, malignancy, immobility, oral contraceptives, pregnancy.
- Inherited thrombophilia: Factor V Leiden, prothrombin gene mutation, protein C/S deficiency.
While traditionally viewed as embolic, emerging data in trauma patients suggest that some pulmonary thromboemboli may develop de novo within the pulmonary vasculature, challenging the paradigm that all PE originates from lower extremity DVT (Knudson 2022).
