Neuroanatomical StudyTopographical features of the vagal nerve at the cervical level in an aging population evaluated by ultrasound
چکیده انگلیسی


- Topographical feature of the vagal nerve is evaluated by ultrasound in 443 patients.
- The 88% of vagal nerves were located in deeper position of carotid sheath at the level of thyroid cartilage.
- Patients with deep type vagal nerve were older than with superficial type ones.
- Topographical feature of the vagal nerve never changed with head rotations.

ObjectiveThe vagal nerve (VN) can be located either dorsal or ventral to the common carotid artery (CCA). We analyzed the correlation between patient age and the depth of the left VN, assessed if patient age is a reliable predictor of VN location, and determined if preoperative ultrasound provides useful information for implantation surgery of a VN stimulator in epilepsy patients.MethodsFrom our database of cervical ultrasonography, examinations of 443 patients (71.8 ± 10.6 years; 332 men and 121 women) were reviewed. The VN, CCA, and internal jugular vein (JV) were identified at the level of the thyroid cartilage. Patients were classified into deep and superficial types in accordance with the relative location of the VN to the line connecting the centers of the CCA and JV (Line C). The ages of the two groups and the correlation between patient age and distance of the VN from line C were analyzed.ResultsThe VN was detected in all 443 patients between the CCA and the JV. The depth of the VN ranged from 7 mm deeper to 6 mm superficial to line C. There were 389 (87.8%) deep and 54 (12.2%) superficial types.ConclusionOur study encourages utilizing longitudinal and cross-individual ultrasound studies within and amongst individuals of different ages to allow understanding the variations of the vagal nerve in its neck portion. This has implications to many neurosurgical procedures.
