  • Title: Venous covered stent: successful occlusion of a symptomatic internal iliac arteriovenous fistula.
    Author: Cronin P, McPherson SJ, Meaney JF, Mavor A.
    Journal: Cardiovasc Intervent Radiol; 2002; 25(4):323-5. PubMed ID: 12042989.
    Abstract:
    We report the placement of a covered stent within the internal iliac vein (IIV) to occlude a symptomatic iatrogenic internal iliac arteriovenous fistula following an abdominal aortic graft. Angiography revealed a direct communication between an internal iliac graft to artery anastomosis and the right IIV with rapid shunting into the inferior vena cava and a small associated pseudoaneurysm. Femoral, brachial or axillary arterial access was precluded. The fistula was successfully occluded by a stent-graft placed in the IIV. Arteriovenous fistula can be treated in a number of ways including covered stent placement on the arterial side. To the best of our knowledge this is the first time placement in a vein has been described. Where access is difficult or the procedure carries a high risk of complication, a venous covered stent may offer an alternative.
