title: [Chronic traumatic arteriovenous fistulae (author's transl)].
abstract: In two patients with femoral arterio-venous fistulae angiography could show arterial and venous collaterals with differing circulation phases. When angiography shows retrograde flow in the artery distal to the fistula, the volume of arterial collateral circulation is unrelated to the peripheral blood-supply. Venous collateral circulation has to be included in the fistular circulation. Angiography permits distinguishing a venous by-pass circulation for the return of blood from the periphery. In one patient a large aneurysm of the iliac vein was found. Special features of angiography, particularly after surgical closure of the fistula, are mentioned.
