title: Arterio-venous shunting complicating occlusive atherosclerotic peripheral vascular disease.
abstract: Three cases of severe occlusive peripheral vascular disease are described in which spontaneous arterio-venous fistulae at the site of atheromatous occlusion have been demonstrated by angiography during the arterial phase. Although none of these patients exhibited specific clinical signs of an arterio-venous fistula, this phenomenon is considered to have been a clinically significant factor in the patients' peripheral ischaemia. In one case both the superficial femoral artery stenosis and the spontaneous shunts were effectively treated by percutaneous angioplasty.
