Renal Arteriovenous Fistula and AV Malformations


Renal arteriovenous fistula:

An arteriovenous fistula is defined as a single pathological communication between the renal artery and vein, most often due to trauma or degeneration.

Renal arteriovenous malformation:

A arteriovenous malformation is defined as multiple pathological communications between artery and vein with a vascular nidus that bypass the capillary bed. Arteriovenous malformations are most often congenital (Cura et al, 2010).

Treatment of renal AV-fistula

Endovascular therapy is the treatment of first choice: selective embolization, occlusion with coils or placement of a stent. Open surgery is reserved for difficult cases. Partial nephrectomy should be attempted in good renal function. (Laparoscopic) nephrectomy is necessary in the absence of renal function or if large AV fistulas cannot be controlled. If present, medical treatment of hypertension and cardiac failure is paramount.
