Resumo

Percutaneous transarterial embolization is a useful, nondrastic, valuable, and commonly used therapeutic option for the treatment of renal arteriovenous malformation (AVM). Compared with partial or total nephrectomy, transarterial embolization is more conservative and preserves renal function. However, it has some limitations and complications that could cause renal infarction and progression of hypertension, renal insufficiency, and pulmonary embolism. Large-sized AVM and multiplicity of abnormal vessels also limit the use of the embolization technique. The authors experienced erosion of the coils and guidewires that were used for embolization of renal AVM from kidney to descending colon. Coil embolization is practiced extensively, but a complication such as this does not appear to have been described.
