Mr Mohamed Elhendawy, FRCS(SN), FEBNS, University Hospital of Wales, Cardiff, UK.
Introduction: Cerebral vasospasm is a major cause of delayed cerebral ischaemia (DCI) following aneurysmal subarachnoid haemorrhage (aSAH) [1]. Sympathetic blockade via stellate ganglion block (SGB) improves cerebral perfusion by reducing cerebrovascular tone [2].
Case Description: A 53-year-old gentleman presented with a modified Fisher grade IV subarachnoid haemorrhage secondary to a ruptured anterior communicating artery (ACOM) aneurysm, treated with endovascular coiling. On post-bleed day 4, he developed symptomatic vasospasm. Despite maximal therapy including oral and intra-arterial nimodipine and hypertensive therapy in the intensive care unit, his neurological condition deteriorated. An ultrasound-guided left stellate ganglion block at C6/7 level was performed using 8 mL of 0.5% levobupivacaine with clonidine 75 mcg. The patient demonstrated immediate neurological improvement, with a reduction in left middle cerebral artery transcranial Doppler (TCD) mean velocity from 246 cm/s to 110 cm/s, without any procedural complications.
Conclusions: Ultrasound-guided stellate ganglion block may represent a safe and rapidly effective adjunctive treatment for refractory cerebral vasospasm following aSAH. Larger studies are needed to further evaluate its utility and establish clinical guidelines [2,3].
Keywords: Aneurysmal subarachnoid haemorrhage; cerebral vasospasm; stellate ganglion block; cervical sympathetic block; neurosurgery.
