Stellate ganglion block catheter for paroxysmal sympathetic hyperactivity: calming the ‘neuro-storm’


Background Paroxysmal sympathetic hyperactivity (PSH) is an autonomic disorder affecting patients with severe acquired brain injury characterized by intermittent sympathetic discharges with limited therapeutic options. We hypothesized that the PSH pathophysiology could be interrupted via stellate ganglion blockade (SGB).

Case presentation A patient with PSH after midbrain hemorrhage followed by hydrocephalus obtained near-complete resolution of sympathetic events for 140 days after SGB.

Conclusion SGB is a promising therapy for PSH, overcoming the limitations of systemic medications and may serve to recalibrate aberrant autonomic states.
