Renal arteriovenous malformation managed with embolization – case report and review of literature

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.
