Renal arteriovenous malformations: diagnosis and treatment

Abstract

Renal arteriovenous fistula is a comparatively rare malformation that accounts for < 1% of all arteriovenous fistulas malformations. Renal ANM are devided into congenital or acquired, traumatic and nontraumatic, that can cause massive hematuria, pain, retroperitoneal hemorrhage, and heart failure. Non-invasive imaging modalities, including US, MDCT and MRI, are widely used to diagnose this payhology, but the gold standard for the diagnosis of renal AVM remains angiography. The advantage of angiography in comparison with other methods is the possibility of simultaneous treatment of such patients. The treatment of renal AVM can include endovascular dissociation of the arteriovenous fistula or an open operation, including the using of ex vivo techniques. The choice of method of the treatment is based on the general patient status and the characteristics of renal arteriovenous malformation.
