RPH after SGB necessitates emergency airway management. Because airway obstruction cannot be predicted by the initial symptoms or signs, emergency airway management tools should be at hand, and the patency of the airway should be continuously evaluated after onset of RPH after SGB.
Three-dimensional computed tomography identified the ITA in the medial portion of the ventral surface of the transverse process of the sixth cervical vertebra. The risk vessels of retropharyngeal hematoma during SGB could include the ITA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
