A prospective study of high resolution ultrasound in brachial plexopathies - Correlation with electrophysiological measurements.

摘要: Objectives Electrophysiological assessment of brachial plexus (BP) lesions is time-consuming and difficult to achieve. Therefore, we wanted evaluate the role ultrasound (US) in a wide spectrum plexopathies establish normative data for correlation. Materials methods We invited sixty-eight consecutive patients referred with symptoms suggestive BP lesion. Forty-three accepted participate. Sixty healthy subjects (HS) were recruited. Following inclusion period all US was anonymised cross-sectional areas (CSA) measured blinded. used Siemens ACUSON S2000 device measure CSA at following levels: (1) roots C5 through C8 just caudal intervertebral foramen, (2) C7 passing between muscles interscalene triangle, (3) upper, middle lower trunk lying posterior subclavian artery above clavicle, (4) lateral, medial cord circumventing axillary artery. Results discussion Out forty-three patients, EDx found signs lesion 16 mononeuropathy nine other six. In HS there no differences sides levels. most levels influenced by age. Cut-off values calculated as means plus 2 standard deviations or age-adjusted regression lines SD. There difference body mass index (BMI) 27.8 (95% CI: 24.3–31.3) 24.1 23.1–25.2) (p = 0.007) but seen gender (p = 0.41) age (p = 0.38). whole patient group, an enlarged least one level (range 1–5) 18 (42%). twenty-five within normal limits. diagnosed 1–3) 11 (69%). five group where normal, 1–2) 3 (27%). both Conclusions could show abnormalities majority conclude that may be anatomical location supplement electrophysiological examination.
