    Post-operative venous thrombosis is common and often undetected clinically. Effective prophylaxis is crucial for reducing pulmonary embolism, especially in high-risk surgical patients. Objective assessment of prophylaxis is key.

    Area of Science:

    • Vascular Surgery
    • Thrombosis Research
    • Diagnostic Imaging

    Background:

    • Venous thromboembolism (VTE) is a significant complication in surgical patients.
    • Clinical diagnosis of VTE is often unreliable.
    • Effective prophylaxis is essential to prevent serious outcomes like pulmonary embolism.

    Purpose of the Study:

    • To assess the incidence of post-operative venous thrombosis in high-risk surgical patients.
    • To evaluate the accuracy of clinical assessment in diagnosing venous thrombosis.
    • To highlight the importance of objective methods for VTE detection and prophylaxis assessment.

    Main Methods:

    • A cohort of 111 high-risk surgical patients was studied.
    • Independent clinical assessment was performed.

  • Venous thrombosis was detected using (125)I-fibrinogen scanning.

    • Main Results:

    • Nearly half of the patients developed venous thrombosis.
    • Two-thirds of thrombotic events were clinically unsuspected.
    • Clinical diagnosis of VTE was falsely positive in 25% of cases.
    • Over 50% of thrombotic episodes were detectable the day after surgery.

    Conclusions:

    • The high incidence and clinical undetectability of venous thrombosis underscore the need for widespread effective prophylaxis.
    • Objective methods like (125)I-fibrinogen scanning are vital for assessing prophylactic strategies.
    • Reducing pulmonary embolism requires improved VTE prevention in high-risk surgical populations.
