[Intravenous digital subtraction angiography following surgical vascular interventions and percutaneous transluminal angioplasty].

I.V.D.S.A. was performed as a follow-up after a surgical vascular procedure or a percutaneous transluminal angioplasty in 157 patients. The quality of the intravenous angiography was excellent in 91% of the patients. In 6,6% the examination was sub-optimal with possible error and in 2.4% the examination was not diagnostic. The inherent limitations of the technique are less important in these follow-up examinations because a limited region only has to be examined. A more accurate follow-up of vascular procedures is possible with I.V.D.S.A.
