Spontaneous contractility in the human lymph vessels

S Armenio, F Cetta, G Tanzini

    Lymphology
    |December 1, 1981
    PubMed
    Summary

    Intrinsic contractility significantly impacts lymph flow in lower limbs, with vessel shape influencing its pattern. This study observed irregular lymphatic pulses, suggesting contractility is key to lymph transport.

    Area of Science:

    • Vascular Biology
    • Physiology
    • Medical Imaging

    Background:

    • Lymphatic system motility is crucial for fluid homeostasis.
    • Understanding intrinsic contractility aids in diagnosing lymphatic disorders.

    Purpose of the Study:

    • To investigate the intrinsic contractility of lower limb lymph vessels.
    • To assess the relationship between lymph vessel morphology and contractility.

    Main Methods:

    • Serial radiography with photographic magnification during diagnostic lymphangiography.
    • Observation of 79 consecutive patients, with analysis of 35 technically satisfactory examinations.

    Main Results:

    • Evident morphological modifications due to intrinsic spontaneous contractility were observed in 74.3% of satisfactory examinations.
    • Contractile activity often appeared irregular, lacking a specific rhythm.
    • Lymphangion size and shape continuously varied, influencing contractility patterns.

    Conclusions:

    • Intrinsic contractility is a significant determinant of lymph flow.
    • Lymphatic chain anatomy, particularly lymphangion morphology, strongly influences contractility patterns.
    • Irregular lymphatic pulses suggest complex regulatory mechanisms.
