  • Title: [Interventional radiology: transoral approach to C2].
    Author: Gabrillargues J, Michel JL.
    Journal: J Radiol; 2008 Feb; 89(2):245-9. PubMed ID: 18354355.
    Abstract:
    PURPOSE: To assess the value of a direct transoral approach to C2 for interventional procedures. MATERIALS AND METHODS: A transoral approach to C2 was used in 4 patients (9-64 year old) with lytic lesion of the C2 vertebra and/or base of the odontoid over a 10 year period. Three patients underwent biopsy and 1 patient underwent vertebroplasty using biplane fluoroscopy. All procedures were performed under general anesthesia using a 13G needle directly introduced in the C2 vertebra through the posterior pharyngeal wall. RESULTS: None of the patients reported ill-effects from the procedure. Needle placement was satisfactory in all patients, without technical difficulty. No technical complication was noted. Specifically, no infectious complication occurred. CONCLUSION: Our results indicate that a direct transoral approach to C2 is safe for biopsy or vertebroplasty.
