Large Vertebral Arteriovenous Fistula Treated With Stent-Grafts-Case Report-

Abstract: A 24-year-old woman presented with neck bruit and thrill. Neurological examination revealed no focal abnormality. Angiography and magnetic resonance imaging showed an arteriovenous fistula (AVF) at the C4-5 levels of the right vertebral artery (VA). The fistula had a single orifice that drained into the epidural veins via the C4-5 intervertebral foramen. A stent-graft was made of a 3.9 cm balloon-expandable stent and an expandable polytetrafluoroethylene graft sutured outside the stent. The stent-graft was adv… Show more

“…This procedure was judged to be technically easier than other options. Although embolization of the fistula with preservation of the parent artery may be the best treatment, 11) we propose parent artery occlusion as a viable treatment choice, which achieved complete obliteration of the fistula in the present case.…”

“…8) Stentgrafts may be superior to coils to preserve the parent artery in arteriovenous fistula with a large orifice. 11) We did not choose a transvenous route because the arteriovenous fistula harbored a large pseudoaneurysm and most of the blood in the right vertebral artery flowed into the fistula. Coil embolization of the parent artery was possible because our patient tolerated the 15-minute balloon occlusion test of the right vertebral artery.…”

“…When disease is limited to VAVF, there have been 13 reports including 15 patients undergoing endovascular treatment, according to our review ( Table 2). 11,[15][16][17][18][19][20][21][22][23][24][25][26] Complete occlusion was achieved immediately after the procedure or at the final follow-up in 14 patients, and the procedure is considered useful in the short term. The prevalence of complications over the longterm following endovascular treatment using a covered stent in the extracranial carotid artery/vertebral artery region is reportedly 9.1% (15/164 cases), and complications included ischemic stroke in 1.2% (two cases), transient ischemic attack in 3.6% (six cases), and acute arterial dissection in 1.8% (three cases) of patients.…”
