Embolization Therapy for a Ruptured Spinal Artery Aneurysm Associated with Spinal Cord Arteriovenous Malformation and Presenting with Spontaneous Subarachnoid Hemorrhage

ABSTRACT

Spinal arteriovenous malformations(AVMs) and aneurysms should be suspected when patient present with subarachnoid hemorrhage and intracranial source has not been identified with neurologic findings attributable to the spinal cord. We report a case of subarachnoid hemorrhage(SAH) with ruptured spinal artery aneurysm associated with spinal cord AVM in 37-year old man who presented with sudden loss of consciousness with paraplegia. The result of CT-head arteriography of the brain was SAH with intraventricular hemorrhage but no intracranial aneurysm was identified. Spinal angiography revealed a cervical spinal cord AVM supplied by anterior spinal artery with an aneurysm in the feeder. The treatment of the spinal cord AVM was performed with liquid coil embolic agent, polyvinylacetylate(PVAc) and feeding artery aneurysm was treated with Guglielmi detachable coils(GDCs).
