ATAIDE, Anderson de Meló Mota et al. Topographic and Biometric Study of the Cervicothoracic Ganglion (Stellate Ganglion). Int. J. Morphol. [online]. 2008, vol.26, n.2, pp. 451-455. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022008000200035.
The cervical sympathetic trunk is a ganglia series joined by interganglionic segments and they are extend along of the lateral faces of vertebral column, from base of the skull until the coccyx. There are a cervical, thoracic, abdominal and pelvic portions. Generally, the sympathetic trunk consists in 21 to 25 ganglia with variable size and received nervous fibers of the thoracic-lumbar portion. We studied 100 sympathetic trunks of formaldehyde-fixed human cadavers of Brazilian individuals, adults, of both sexes. The cervicothoracic ganglion was observed in 70% of the cases and was formed by cervical inferior ganglion fused with the first thoracic sympathetic ganglion in75.7 % of them; itwas spindle shaped in 44.2 % or irregular in the samepercentage. The average of length, width and thickness werel 8.0 mm, 5.3 mm and 3.7 mm, respectively. Its shape and localization is variable but with a detailed knowledge of its topographic and biometric relationships, the surgical approach in the región of cervico-thoracic transition will be more sure.
