Acute Paraplegia After Aneurysmal SAH: A Case Report of a Rare Complication and Review of the Literature.

BACKGROUND: Paraplegia after intracranial aneurysmal subarachnoid hemorrhage (SAH) is a rare condition, and its pathogenesis is still unclear. CASE DESCRIPTION: We present a case of a ruptured basilar dissecting aneurysm treated with the stent-assisted coiling procedure. Progressive weakness of the lower limbs developed within 5 days postoperatively. Spinal magnetic resonance image showed SAH accumulation in the lumbosacral area. Emergency lumbar drainage was performed, and the patient's symptoms improved dramatically. CONCLUSIONS: To the best of our knowledge, this is the first report to describe the successful treatment of paraplegia after intracranial aneurysmal SAH.
