    Summary

    Carotid body tumors, a rare paraganglioma, are often misdiagnosed. Advanced imaging and catecholamine testing improve diagnosis, while surgical techniques have significantly reduced mortality for this APUDoma.

    Area of Science:

    • Oncology
    • Vascular Surgery
    • Endocrinology

    Background:

    • Carotid body tumors (paragangliomas) are rare, often presenting diagnostic challenges.
    • A significant percentage of patients undergo surgery without a definitive preoperative diagnosis.
    • The malignant potential of these tumors is well-established.

    Purpose of the Study:

    • To review the diagnostic and surgical management of carotid body tumors.
    • To highlight advancements in diagnostic workup and surgical techniques.
    • To emphasize the importance of early and accurate diagnosis.

    Main Methods:

    • Retrospective analysis of 44 carotid body tumor cases over 40 years.
    • Review of diagnostic modalities including ultrasonography, radioisotope perfusion scanning, and selective carotid arteriography.
    • Evaluation of surgical outcomes and mortality rates associated with different surgical techniques.

    Main Results:

    • 18 patients (43%) lacked a primary working diagnosis pre-surgery.
    • Improved preoperative workup significantly enhances diagnostic accuracy.
    • Modern surgical techniques preserving carotid circulation have drastically reduced mortality from 50% to less than 3%.

    Conclusions:

    • Accurate preoperative diagnosis of carotid body tumors is crucial.
    • Advanced imaging and biochemical tests (catecholamines) are recommended.
    • Surgical management has evolved, leading to improved patient survival and reduced morbidity.
