Occlusion of acquired renal arteriovenous fistula with transcatheter electrocoagulation

Therapeutic intervention in renal arterial injuries

“…However, large lesions have an unpredictable natural history, and aggressive treatment is often warranted in lesions with hemorrhage worsening symptoms, and progressive enlargement [60][61][62][63]. Intraparenchymal AVF can often be successfully managed with mechanical occlusive devices (balloons [16], coils ]64], isobutyl-2-cyanoacrylate (Bucrylate) [5,30], or transcatheter electrocoagulation) [38]. Small aneurysms and bleeding vessels can be managed with Gelfoam.…”

“…Other agents that have been used include stainless steel "spiders" [32], bristle brushes [33], microfibrillar collagen hemostat [34], detachable silicone balloons [35], polyvinyt alcohol foam [36], and alcohol [37]. Highly selective and desirable vascular occlusion has been obtained with transcatheter electrocoagulation [38]. Autologous clot, either in its native state or denatured with epsilon amino caproic acid, has also been effectively used [3,10,12].…”
