Digital subtraction angiography in postoperative evaluation of peripheral vascular disease.

The authors present the results of intravenous Digital Subtraction Angiography (DSA) in 41 patients examined after vascular surgery for peripheral disease. The digital technique has always been able to show the patency of the graft or the existence of complications (obstruction, stenosis, pseudoaneurysm), even in asymptomatic patients. The images were of good or excellent quality in 90% of the cases. The equipment with C-arm proved to be very useful for the oblique projections which were required in about 20% of the examinations.
