title: [Digital subtraction angiography of acquired arteriovenous fistulas of the extremities].
abstract: The signs of arterio-venous fistulae in the extremities have been evaluated by DSA in 20 patients. Angiographic signs for the presence of A-V fistulae are the following findings: dilatation of the supplying artery, elongation of the supplying artery, solitary A-V aneurysm, angiomatous A-V aneurysm, reduced blood flow distal to the A-V fistula, early venous filling, development of a venous collateral circulation and demonstration of retrograde venous flow. Angiography remains the method of choice for demonstrating A-V fistulae.
