Park, Donghwi; Ryu, Ju Seok
- Abstract
<bold>Background: </bold>To the authors' knowledge, there has not been an ultrasound study of the vulnerable vessels in a C3-7 cervical nerve root block (CNRB).<bold>Objectives: </bold>To evaluate the prevalence of vulnerable vessels around the target of a CNRB at the cervical nerve root of C3-7 levels in a clinical setting.<bold>Design: </bold>Retrospective, cross-sectional study.<bold>Setting: </bold>General teaching hospital, rehabilitation unit.<bold>Participants: </bold>A total of 104 patients complaining of neck or arm pain with no prior surgical history and who had undergone a CNRB at an outpatient clinic from May 2015 to December 2017 were included.<bold>Main Outcome Measurements: </bold>The prevalence of vulnerable vessels as seen on a preprocedure ultrasound scan around the target of a CNRB at the cervical nerve root of C3-7 levels.<bold>Results: </bold>Out of 104 cases, the C3 level had 7 blood vessels (8.33%), the C4 level had 14 blood vessels (13.86%), the C5 level had 17 blood vessels (16.35%), the C6 level had 27 blood vessels (25.96%), and the C7 level had 31 blood vessels (29.81%) either at the targeted cervical nerve root or at the site of the imaginary needle's projected pathway to the targeted cervical nerve root.<bold>Conclusion: </bold>There was a substantial prevalence of vulnerable vessels either at the targeted nerve root or at the site of the needle's projected pathway to the nerve root.
