Arterial ligation in epistaxis.

H E Stone, J Rogers

    The Australian and New Zealand Journal of Surgery
    |April 1, 1978
    PubMed
    Summary
    This summary is machine-generated.

    Severe nosebleeds may necessitate arterial ligation. This study maps nasal vascularity and ligation effects, revealing up to three systems (external carotid, ethmoidal arteries) may require occlusion based on bleeding site.

    Area of Science:

    • Anatomy
    • Vascular Surgery
    • Otolaryngology

    Background:

    • Unremitting, severe epistaxis (nosebleeds) can be a debilitating condition.
    • Surgical intervention, including arterial ligation, is sometimes required for intractable cases.
    • Understanding the nasal vascular supply is crucial for effective surgical management.

    Purpose of the Study:

    • To delineate the vascular anatomy of the nose.
    • To investigate the anatomical consequences of ligating specific arteries supplying the nasal region.
    • To inform surgical strategies for managing severe epistaxis.

    Main Methods:

    • Vascular systems of 14 human cadavers were visualized using dye injection.
    • The study analyzed the territories supplied by the four main vascular systems of the nose.

  • Simulated arterial ligations were performed to assess their impact on nasal vascularity.

    • Main Results:

    • The study identified the key arterial systems supplying the nose: ipsilateral and contralateral external carotid arteries and ipsilateral ethmoidal arteries.
    • Ligation of one or more of these systems was shown to be feasible.
    • The number of arterial systems requiring occlusion (up to three) depended on the specific site of nasal hemorrhage.

    Conclusions:

    • Arterial ligation is a viable option for severe epistaxis.
    • Targeting specific vascular pedicles, including external carotid and ethmoidal arteries, can effectively control nasal bleeding.
    • Surgical planning should consider the precise location of the hemorrhage to determine the optimal ligation strategy.
