Postoperative hypertension associated with radical neck dissection.

W F McGuirt, J S May

    Archives of Otolaryngology--Head & Neck Surgery
    |October 1, 1987

    Summary

    Postoperative hypertension is a risk after radical neck dissection, affecting over 10% of patients. This condition, potentially caused by carotid sinus denervation, can lead to complications like hemorrhage.

    Area of Science:

    • Cardiovascular Surgery
    • Oncology
    • Anesthesiology

    Background:

    • Radical neck dissection is a surgical procedure often performed for head and neck cancers.
    • Postoperative hypertension is a potential complication that requires careful monitoring and management.

    Purpose of the Study:

    • To investigate the incidence and characteristics of hypertension following radical neck dissection.
    • To identify potential causes and consequences of this postoperative hypertension.

    Main Methods:

    • A prospective study of 94 consecutive patients undergoing radical neck dissection.
    • Continuous monitoring of blood pressure in the immediate postoperative period.
    • Analysis of blood pressure trends, duration, and need for intervention.

    Main Results:

    • 9.6% of patients experienced severe postoperative hypertension (≥200/100 mm Hg or significant elevation above baseline).
    • Hypertension typically occurred within the first two postoperative hours and lasted approximately nine hours.
    • Two patients experienced postoperative hemorrhage and flap hematoma attributed to hypertension; six required interventional therapy.

    Conclusions:

    • Reflex hypertension following radical neck dissection may result from carotid sinus denervation.
    • The procedure itself, including tumor stripping or graft placement on the carotid artery, did not significantly influence hypertension development.
    • Close monitoring and timely intervention are crucial for managing postoperative hypertension and preventing complications.
