Traumatic carotid-cavernous sinus fistula

R A Sofferman, R L Fabian

    The Laryngoscope
    |July 1, 1977
    PubMed
    Summary

    Carotid-cavernous sinus fistulae, often from head trauma, present with a pulsatile bruit and eye swelling. Early recognition by maxillofacial surgeons is crucial to prevent complications from misdiagnosed facial fractures.

    Area of Science:

    • Neurology
    • Ophthalmology
    • Vascular Surgery

    Background:

    • Carotid-cavernous sinus fistulae (CCSF) are abnormal connections between the carotid artery and the cavernous sinus.
    • High-velocity head trauma is the cause in 75% of CCSF cases.

    Observation:

    • The most frequent symptom is a pulse-synchronous bruit, audible once consciousness is regained.
    • Objective signs are typically unilateral, affecting the ipsilateral orbit.
    • Pathognomonic signs include a periorbital bruit and engorged conjunctival veins.

    Findings:

    • Bilateral carotid angiography is essential for diagnosis and treatment planning.
    • Diagnosis and treatment require awareness of potential delays in symptom presentation.
    • Prompt identification prevents premature surgical intervention for facial fractures.

    Implications:

    • Maxillofacial surgeons must be vigilant for CCSF to avoid iatrogenic complications.
    • Understanding CCSF presentation is vital for appropriate patient management.
    • Timely diagnosis ensures correct treatment, preventing severe outcomes.
