+

  • • Rare

    • May occur anywhere along extracranial portion

++

Epidemiology

++

True Aneurysms

+

  • • Caused by

    • -Atherosclerosis

      -Occasionally by cystic medial necrosis, Marfan syndrome, or fibromuscular dysplasia

++

False Aneurysms

+

  • • Occur rarely after carotid endarterectomy

    • Occur as result of trauma, or infection (pharyngeal abscess)

++

Symptoms and Signs

+

  • • Pulsatile neck mass

    • Dysphagia can occur from protrusion into oropharynx

    • Neck pain, radiating to jaw

    • 30% present with transient ischemic attacks

    • Rupture (more common with false aneurysms) into oropharynx, ear canal, soft tissues of neck

++

Imaging Findings

+

  • Duplex US: Initial test

    • Arteriography necessary to plan surgery

+

  • • Duplex US will differentiate redundant carotid artery from aneurismal and identify occlusive disease

++

Rule Out

+

  • • Coiled or redundant carotid artery, subclavian artery (can present as pulsatile neck mass)

+

  • • Duplex US

    • Angiography prior to surgery

    • Consider CT if infection or traumatic

+

  • • If accessible, resect and replace aneurysm with graft or vein

    • Endovascular stenting may be an option

    • False aneurysms should be repaired

    • Can ligate extensive aneurysm if back pressure > 65 mm Hg

    • -Can identify potential candidates with awake arteriography and balloon occlusion

++

Surgery

++

Indications

+

  • • True or false aneurysm

++

Prognosis

+

  • • Good if repairable
