    Prophylactic vena caval clipping during major abdominal vascular surgery effectively prevents fatal pulmonary embolism in high-risk patients. This adjunctive procedure showed no increase in mortality or morbidity, making it a safe and recommended intervention.

    Area of Science:

    • Cardiovascular Surgery
    • Vascular Surgery
    • Surgical Oncology

    Background:

    • Pulmonary embolism (PE) is a significant cause of mortality following major surgery, particularly in high-risk individuals.
    • Animal studies indicated myocardial dysfunction after vena caval ligation but not after clipping.
    • Inferior vena cava (IVC) interventions are crucial in preventing PE.

    Purpose of the Study:

    • To evaluate the safety and efficacy of concomitant vena caval clipping as a prophylactic measure against PE in major abdominal vascular procedures.
    • To assess the impact of IVC clipping on patient mortality and morbidity.

    Main Methods:

    • A four-year prospective study involving patients undergoing major abdominal vascular procedures.
    • Concomitant prophylactic clipping of the inferior vena cava was performed in patients at high risk for PE.

  • Outcomes including mortality, morbidity, and PE-related deaths were meticulously recorded.

    • Main Results:

    • No deaths were attributed to pulmonary embolism in the study cohort.
    • The addition of vena caval clipping did not result in increased mortality or morbidity.
    • No procedure-related complications were observed due to the clipping itself.

    Conclusions:

    • Concomitant prophylactic vena caval clipping is a safe and effective adjunctive procedure for preventing PE in high-risk patients undergoing laparotomy.
    • This prophylactic strategy significantly reduces the risk of fatal pulmonary embolism without compromising patient safety.
    • The findings support the routine consideration of IVC clipping in selected patients at high risk for PE.
