Summary: | ABSTRACT Describe a 2-patient case report of a rare occurrence of significantly increased anxiety after a left-sided stellate ganglion block (SGB) and the subsequent improvement of that anxiety through a right-sided SGB. Right-sided SGB to treat post-traumatic stress disorder (PTSD) has over 23 supporting publications in the peer-reviewed medical literature, including level 1 evidence. A published case series of 285 patients showed that two-level SGB may improve anxiety-related symptoms in patients. However, a recently published study indicates that some patients only respond to a left-sided SGB. The patients had an ultrasound-guided right-sided SGB for the treatment of PTSD and experienced a reduction in anxiety symptoms based on Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) scores. Later, a left-sided SGB was performed. Clinically, the addition of a left-sided SGB is typically associated with further anxiety reduction, but in these 2 cases, the patients had a significant reversal of the improvements experienced after a right-sided SGB. Following this unusual response to a left-sided SGB, these patients were offered another right-sided SGB, after which, they experienced a significant and durable improvement in anxiety symptoms beyond the original baseline PCL-score. In rare cases and for unknown reasons, a left-sided SGB may result in acute worsening of anxiety symptoms, which can be addressed and significantly improved with the application of a subsequent right-sided SGB. |
