    Area of Science:

    • Physiology
    • Biomedical Engineering
    • Surgical Techniques

    Background:

    • Microvascular flowmetry is essential for assessing blood flow in small vessels.
    • Challenges exist in achieving stable zero-line readings and accurate calibration of flow probes.
    • Existing methods require refinement for improved reliability.

    Purpose of the Study:

    • To investigate and resolve issues in microvascular flowmetry.
    • To enhance zero-line stability through meticulous vessel wall preparation.
    • To address calibration challenges associated with small electromagnetic flow probes.

    Main Methods:

    • Utilized microsurgical principles and tools, including a binocular microscope.
    • Employed electromagnetic flow probes with inner diameters of 2, 1.5, and 1 nm.
    • Conducted studies on zero-line drifting and calibration in rats and rabbits.

    Main Results:

    • Demonstrated improved flow uptake and zero-line stability using the described preparation technique.
    • Highlighted the importance of precalibrating small flow probes with laboratory animals when in-situ calibration is not feasible.
    • Validated the efficacy of microsurgical techniques for vessel preparation.

    Conclusions:

    • Microsurgical preparation of the vessel wall significantly improves zero-line stability in microvascular flowmetry.
    • Precalibration of flow probes in animal models is recommended for accurate measurements.
    • The study advocates for the adoption of microsurgical techniques in this field.
