Treatment of vertebral arteriovenous fistulas

Endovascular Treatment of Traumatic Injuries of the Vertebral Artery

“…Although ischemic events, contrast media reactions, and clinical deterioration have been described after treatment of AVFs, 3,[16][17][18][19] the absence of complications in our series and that of Beaujeux et al 12 shows that this technique can be a safe method of management for this pathology.…”

“…The clinical information was introduced into a data base, including variables referring to topography and morphology of vertebral artery lesions previously established elsewhere. 3,12 Information about clinical presentation, endovascular techniques used, and angiographic and clinical outcomes of treatment was registered. All procedures were performed with the patient under moderate conscious sedation with neuroleptanalgesia, allowing regular clinical and neurologic evaluation, except for an 11-year-old patient who required general anesthesia.…”

“…AVFs compromising the vertebral artery are rare lesions, defined by the presence of an abnormal shunt between the extracranial vertebral artery or 1 of its muscular or radicular branches and an adjacent vein. [1][2][3] These lesions can be of traumatic or spontaneous origin. [1][2][3][4][5][6] Traumatic fistulas are frequently associated with penetrating neck injuries.…”

“…[1][2][3] These lesions can be of traumatic or spontaneous origin. [1][2][3][4][5][6] Traumatic fistulas are frequently associated with penetrating neck injuries. [7][8] Less frequent causes include puncture of the vertebral artery after gaining jugular vein access for central line placement, neck surgery, dislocations, and fractures of the cervical spine.…”

Central venous catheter misplaced in the vertebral artery

“…For many years, transvascular embolization has been the treatment of choice for vertebral arterio-venous fi stulas [18]. In order to preserve the patency of the vertebral artery, the fi stula track has to be embolized either by an arterial, venous or combined approach.…”
