  • Title: Iatrogenic vertebral arteriovenous fistula treated with a hemobahn stent-graft.
    Author: Priestley R, Bray P, Bray A, Hunter J.
    Journal: J Endovasc Ther; 2003 Jun; 10(3):657-63. PubMed ID: 12932183.
    Abstract:
    PURPOSE: To illustrate the utility of color flow duplex ultrasound (CFDU) in the diagnosis and stent-graft treatment of a rare arteriovenous fistula (AVF) involving the vertebral artery and vein. CASE REPORT: An iatrogenic AVF involving the right vertebral artery and vein was diagnosed in a 45-year-old man using CFDU. Treatment was recommended due to the large volume of blood shunted through the fistula and the associated loud bruit. Endoluminal treatment involved deployment of a covered stent within the vertebral artery to exclude the fistula. Postoperative CFDU confirmed the success of the treatment. CONCLUSIONS: CFDU can be utilized to accurately diagnose unusual lesions, such as AVFs involving the vertebral artery. The technique is also useful in planning treatment and monitoring the durability of stent-grafts implanted to obliterate this type of defect.
