Abstract

Introduction: Computed tomography-guided cervical nerve root corticosteroid injections are a commonly performed procedure for cervical radiculopathy. There have been major complications such as spinal cord infarction and posterior circulation stroke reported mostly with X-ray fluoroscopic-guided methods, however, there is relatively little data on the safety of newer CT-guided methods. The purpose of this study was to identify any major complications and evaluate the rate of minor complications from CT-guided cervical nerve root corticosteroid injections performed in a tertiary public hospital. Methods: Four hundred and three CT-guided cervical nerve root injection procedures were identified over a period from July 2015 to January 2018 using the radiology information system (RIS) and data collected about the technique and any immediate complications. Patient follow-up and delayed complications were then reviewed, either via outpatient clinic records or telephone consultation. Results: Two hundred and eighty-six procedures were performed by radiology registrars or fellows, and 117 by radiologists, most commonly via an anterolateral approach and injecting 4 mg (in 1 mL) of dexamethasone. Follow-up data were obtained for all 403 procedures and identified 16 minor complications, but no major neurovascular complications. Conclusion: The overall recorded rate of minor complications with CT-guided nerve root injection was 4.0% with no major neurovascular complications, suggesting that CT-guided transforaminal cervical corticosteroid injection is a safe procedure.
