Applied anatomy of stellate ganglion block / 第三军医大学学报

ABSTRACT

Objective To study the anatomical characteristics of the stellate ganglion (SG) for providing morphological data for SG block. Methods The shape, size, position, and relation of 30 cases of SG in 15 adult cadavers were observed and measured. Results Most of the SG was stellate-shaped. The average volume of the stellate ganglion was (0.86?0.07)cm3. The position of the SG could be localized according to the adjacent bone or muscle marks, and the shortest distance was between the SG and the transverse process of the 7th cervical vertebrae. There were many important structures around the SG, in which the vertebral artery was closely related to the SG. Conclusion During performance of the SG block, the surface projection, puncture point, and medication dosage could be judged on the basis of these quantitative anatomic data.
