Stellate Ganglion Block Attenuates Cerebral Vasospasm after Aneurysmal Subarachnoid Hemorrhage in the Setting of Moyamoya Disease

Friday, November 14, 2025
3:30 PM - 3:38 PM CT
Location: Griffin Hall - Screen 02
Introduction: Cerebral angiographic vasospasm occurs in approximately 40% of patients with
aneurysmal subarachnoid hemorrhage (1), often leading to delayed cerebral ischemia and poor
clinical outcomes. While conventional management strategies include hemodynamic
augmentation, calcium channel blockers, and endovascular interventions (2), the stellate
ganglion block (SGB) has emerged as a safe, potential adjunct therapy due to potent
modulation of sympathetic tone and reduced mean cerebral blood flow velocity (3,4).
