Intravenous digital subtraction angiography in patients with femoral arteriovenous fistulas and ilio-iliac crossover graft.
Fourteen patients with femoral arteriovenous (AV) fistulas and ilio-iliac crossover bypass grafts after postthrombotic occlusion of an iliac vein were studied by intravenous digital subtraction angiography (IV DSA). Digital radiography's utility may be evaluated in the demonstration of the vascular status of AV fistulas and venous return through the reopened iliac vein or ilio-iliac graft. Digital subtraction imaging is a suitable modality to plan operations, such as closure of temporary AV fistula. In follow-up studies of these cases, patency of the crossover bypass can be assessed by noninvasive DSA of the ascending veins.
