Abstract

Abstract : Introduction: Carotid occlusion is a rare but serious complication of retropharyngeal abscess (RPA). Management questions that must be addressed include the choice between reconstruction and occlusion in the setting of an active infectious process. Case Report: A 4 year old female presented with hoarseness, shortness of breath, and a right-sided Horner's syndrome. A CT scan confirmed the diagnosis of RPA, and contrast studies showed no filling in the right internal carotid artery (ICA). Surgical exploration of the abscess disrupted the occluded artery, causing deep, uncontrolled bleeding. Emergent angiographic evaluation was completed, and the decision was made to sacrifice the ICA. The patient recovered on antibiotics, but the Horner's syndrome persisted. Discussion: The presence of a carotid artery occlusion must be ruled out in the setting of a RPA. When suspected, it should be investigated further. Therapeutic decisions regarding sacrifice or reconstruction of the carotid artery are burdened by risks associated with the setting of an infection, notably infection and systemic dissemination. Conclusion: The presence of a carotid occlusion is a serious complication resulting from a RPA that can lead to permanent neurological deficit. Endovascular vessel sacrifice is a viable treatment option for carotid occlusion in the setting of a retropharyngeal abscess, but must be considered on a case-by-case basis.
