Type: article

Abstract: Renal arteriovenous malformations are uncommon. It is classified according to its cellular characteristics (hemangiomas or vascular malformations), according to vascular flow (high or low flow), according to arterial, venous, arteriovenous, lymphatic or combined predominance and according to its clinical behavior.1,2 Renal arteriovenous fistulas can be of congenital origin (22–25%), idiopathic (3–5%) or acquired (70–75%).2,3 High-flow vascular malformations (congenital) are called cirsoid aneurysms when they acquire a nest disposition.2 Acquired aneurysms are more frequent and may be secondary to renal traumas, tumors or iatrogenic causes such as: renal biopsy, percutaneous renal surgery, percutaneous nephrostomy, open surgery and extracorporeal shock wave lithotripsy.1,2,4
