    Area of Science:

    • Vascular Surgery
    • Medical Imaging
    • Hemodynamics

    Background:

    • Deep vein thrombosis (DVT) diagnosis and hemodynamic consequence assessment require effective experimental models.
    • Current diagnostic methods for DVT may benefit from advanced simulation tools.

    Purpose of the Study:

    • To develop and validate a device for creating experimental popliteal vein thrombosis.
    • To assess the utility of this device in conjunction with noninvasive diagnostic techniques.

    Main Methods:

    • A device was engineered using a syringe piston, manometer, and pump to apply graded pressure.
    • Autologous red blood cells labeled with 99Tcm were used for scintigraphy.
    • Plethysmographic venous emptying recordings were performed.
    • A cobalt marker controlled piston positioning during gamma-camera imaging.

    Main Results:

    • The developed device successfully induced experimental popliteal vein thrombosis.
    • The experimental setup was effective for visualizing thrombosis with scintigraphy.
    • Plethysmographic recordings provided data on venous emptying.

    Conclusions:

    • The device is a successful tool for inducing experimental popliteal vein thrombosis.
    • This model can be utilized for evaluating noninvasive diagnostic methods for DVT.
    • It facilitates the study of hemodynamic consequences of acute venous thrombosis.
