Safety and effectiveness of cervical vertebroplasty: report of a large cohort and systematic review.

Abstract

To evaluate retrospectively safety and effectiveness of cervical vertebroplasty (cVP) based on a single-center large cohort. All cVP performed at a single center from January 2001 to October 2014 were included and reviewed. Procedure-related complications (minor and major) were systematically recorded. Effectiveness in terms of analgesia was evaluated using a semi-quantitative grading scale at 1-month follow-up. Risk factors for the occurrence of a procedure-related complication or cement leakage, as well as factors influencing pain relief at 1-month follow-up, were evaluated using a multivariate analysis. One hundred and forty cVP procedures (176 vertebrae) were performed in 130 consecutive patients (88 female, 42 male; mean age = 56 years) during the inclusion period. Among the treated lesions, 80% were bone metastases (mostly from breast cancer), 8% were related to hematological malignancies, and 12% were non-malignant lesions. One fatal complication (0.7%) was related to cement migration in the vertebrobasilar system. Three cervical hematomas were recorded, one of them requiring prolonged oral intubation. The overall rate of major complications was 1.5%. At 1 month, pain reduction was observed in 76% of the cases. Additional surgical fixation was required in 6.1% of the cases. cVP of more than one vertebra during the same session was an independent risk factor for procedure-related complications. Cervical vertebroplasty is a safe technique with an acceptable major complication rate. Its effectiveness in terms of pain relief is good at mid-term follow-up. • Cervical vertebroplasty (cVP) is a safe procedure with a low rate of major complications (1.5%). • cVP provides pain relief in 76% of the cases. • Additional fixation surgery is rarely required after cVP (6.1% of the cases).
