- Aneurysmal degeneration of the origin of an aberrant subclavian
- Arteria Lusoria)
- Incidence 0.5%
- Arises from Aorta distal to Left Subclavian Artery and courses behind the oesophagus
- Associated with a non-recurrent laryngeal nerve
- May compress the Oesophagus against the Trachea → “Dysphagia Lusoria”
- Clinical
- Typically asymptomatic
- Symptoms
- Dуѕрhаgia from esophageal compression by the аոеuryѕm (termed ‘ԁyѕрhagia lusoria’)
- Cough or ѕtridоr from tracheal irritation or compression
- Chest pain due to аոeսrуsm expansion or rupture
- Symptoms of ischemia such as exercise-induced аrm fatigue
- Treatment
- Almost always Repair - resection of the restricting structure & arterial replacement
- No guideline regarding the diameter for asymptomatic Kommerell diverticulum given its rarity, but a diameter threshold of >3 cm has been proposed
