Resumo

Vascular malformations of the kidney are pathologic processes that involve renal veins and arteries and include arteriovenous malformations (AVMs) and arteriovenous fistulas (AVFs). These lesions may present with a wide range of signs and symptoms that vary from hypertension, hematuria to renal masses. The presence of arterio-venous shunting characterizes AVMs and AVFs. We report the case of a congenital renal AVM in a woman who presented with hematuria and was successfully treated with endovascular embolization in an emergency setting. The lesion was selectively catheterized with a microcatheter and embolization was performed by injection of a mixture containing n- butyl 2-cyanoacrylate (NBCA) and lipiodol. Diagnostic imaging modalities and the technique of embolization are discussed.
