Renal Arteriovenous Fistula

Renal arteriovenous fistula is an abnormal communication between renal artery and vein (congenital, traumatic, or iatrogenic after biopsy), causing hypertension, hematuria, or high-output heart failure with large shunts. Treatment: observation for small asymptomatic; endovascular embolization; surgical repair/partial nephrectomy for symptomatic, hypertensive, hemorrhagic, or high-flow fistulas; control BP; monitor renal function.

Common Symptoms

Hypertension; hematuria; bruit; high-output HF; by congenital/traumatic/iatrogenic

Causes and Pathogenesis

Congenital/traumatic/biopsy-related shunt causes renal arterial-venous communication and hemodynamic effects.

Treatment

Observe small; embolize/surgery for symptomatic/hypertensive/hemorrhagic/high-flow

Preventive Measures

Careful renal biopsy; treat before complications.

Department to Visit
