Multiple Spontaneous Iliac and Femoral Arteriovenous Fistulas

An arteriovenous fistula (AVF) in a limb involves an abnormal connection between a limb artery and vein. It can be due to trauma or iatrogenic injury. Traumatic AVFs can be caused by penetrating or gunshot injuries to the limb, whereas iatrogenic causes include catheter intervention to the groins or open surgery of the inguinal space. By contrast, the occurrence of multiple spontaneous AVFs is rare. We report a case of endovascular therapy for multiple spontaneous AVFs between the iliac artery and the vein, common femoral artery and the vein, superficial artery and the saphenous vein, and deep femoral artery and the vein.
