  • Title: Cervical cord decompression following embolisation of a giant cervical vertebro-vertebral arteriovenous fistula.
    Author: Tse GH, Patel UJ, Coley SC, Dyde RA.
    Journal: Interv Neuroradiol; 2017 Aug; 23(4):399-404. PubMed ID: 28583042.
    Abstract:
    Arteriovenous fistulation between the vertebral arteries to extradural (epidural) veins, termed vertebro-vertebral arteriovenous fistulae, are uncommon diagnoses without established diagnostic algorithms or treatment options. Minimal evidence exists describing the management of this pathology. Endovascular treatment was performed under general anaesthesia by coil occlusion of the vertebral artery from the point of the fistula to the mid-vertebral artery. Repeat magnetic resonance angiographic imaging one week following the procedure confirmed an 80% reduction in the size of the epidural vein and decompression of the cervical spinal cord. At four-week follow-up there was significant qualitative improvement in the myelopathic symptoms including walking distance and pain. Normal physiological filling of the collapsed extradural vein was observed on follow-up digital subtraction angiography at five months. Catheter angiography by an experienced interventional neuro-radiologist is critical in defining the anatomy and providing minimally invasive treatment.
