Posterior Shoulder Dislocation As a Post-Operative Complication of Carotid Endarterectomy: Case Report and Review of Literature

Abstract

Changes in blood pressure after carotid endarterectomy (CEA) may lead to the cerebral hyperperfusion syndrome (CHS), which might be accompanied by postoperative seizures. We report a case of a 71year old man that underwent left CEA and developed a tonic-clonic seizure in the recovery room after hearing a familiar voice. Physical and radiological imaging revealed a massive rotator cuff tear and locked posterior shoulder dislocation of the right humerus with a large impaction fracture. He was successfully treated with a reverse shoulder arthroplasty and gained good functional results.
