    Postmastectomy "big arm" (lymphedema) is likely caused by hindered venous reflux after mastectomy. Surgical bypass of the blocked vein may improve or resolve this condition.

    Area of Science:

    • Vascular Surgery
    • Oncology
    • Medical Imaging

    Background:

    • Postmastectomy lymphedema, or "big arm," is a debilitating condition affecting women after breast cancer surgery.
    • Several pathogenetic theories exist, with hindered venous discharge gaining prominence.

    Purpose of the Study:

    • To investigate the role of hindered venous discharge in postmastectomy "big arm."
    • To present clinical cases and suggest a potential treatment strategy.

    Main Methods:

    • Review of pathogenetic theories of postmastectomy "big arm."
    • Phlebographic imaging to illustrate venous abnormalities in affected patients.
    • Analysis of 41 observed cases of postmastectomy "big arm."

    Main Results:

    Related Experiment Videos

    • Phlebographic evidence supports hindered venous reflux as a probable cause of postmastectomy "big arm."
    • Observed cases demonstrated venous thrombosis or compression secondary to mastectomy.

    Conclusions:

    • Postmastectomy "big arm" is strongly associated with hindered venous reflux in the upper limb.
    • Surgical intervention, such as venous bypass, is proposed to improve or resolve the condition.
