Transient ischemic attack and ischemic upper limb in a case of subclavian artery pseudoaneurysm due to complicated clavicular bone fracture, a rare encounter

Abstract

Background: Subclavian pseudoaneurysm is a rare sequalae of untreated ipsilateral clavicular bone fracture and may be complicated with distal embolization, causing an acute ischemia of ipsilateral upper limb. Case Presentation: We present a challenging case of subclavian pseudoaneurysm who was later discovered to have a previously missed clavicular bone fracture. The case was complicated with concurrent recurrent ischemic limb and transient ischemic attack of the brain. Conclusion: Although subclavian artery pseudoaneurysm as a cause for transient ischemic attack has not been described in literature, we believe that our case has highlighted the possibility of such association.
