Subluxation of the mandible for access to high carotid bifurcation in a patient with iodinated contrast induced parotitis: case report and literature review

Abstract

Atherosclerotic disease of the extracranial carotid arteries can cause complications with high morbidity and mortality rates. The contrast imaging examinations used in preoperative evaluation are associated with complications such as parotitis, in addition to well-known allergic reactions and renal dysfunction. A high carotid bifurcation or atherosclerotic disease that extends distally are often limiting factors for conventional surgical treatment. However, when iodinated contrast is contraindicated or endovascular treatment is not feasible, knowledge of surgical techniques that allow safe endarterectomy is required. Subluxation of the mandible has proven to be a safe and effective adjuvant technique that is easy to perform and reproducible, providing access to high carotid bifurcations with good exposure of the surgical field and allowing endarterectomy to be performed with a standard technique. We present the case of a patient with a high carotid bifurcation and limitations for use of iodinated contrast who underwent carotid endarterectomy after subluxation of the mandible.
