Abstract

To evaluate the efficacy and safety of the interventional techniques for treatment of acquired arteriovenous fistulas (AVF). Ten patients with acquired AVFs, including 4 with renal AVF, 3 with iliac AVF, and 3 with subclavian AVF, were treated with interventional procedures. The etiological factors of the AVFs were penetrating trauma in 5 cases, iatrogenic injury in 3, malignancy in 1, and intestine Crohn's disease in 1. The patients presented with peripheral venous hypertension (n = 6), local bruit (n = 10), cardiac overload (n = 10), the right cardiac failure (n = 2), and hematuria (n = 4). Three patients underwent transcatheter super-selective coils embolization and 7 underwent stent-graft placement in the involved arteries. The technical success was achieved in all cases. Completion angiography documented complete exclusion of the fistulas. Minor complications occurred in 3 patients, but without significant consequences. The patients experienced immediate relief of the limb swelling, peripheral venous hyperemia, and tachycardia. The local bruit was disappeared. The cardiac overload conditions were improved significantly, which was confirmed by ultrasound scan. Renal function tests in patients with renal AVF were stable. Rad...Continue Reading
