Intraarterial digital subtraction angiography after plastic surgery by thin-needle puncture

Over the period of a year (1983), 44 intraarterial digital subtraction angiographies (DSA) via direct thin-needle puncture of a vascular bypass or following vascular graft were carried the rough. The only complication that occured: paravasal injection, was clinically insignificant and could be avoided by a change in the puncture-technique. It was possible to carry through the investigation in out-patients. In all cases, diagnostically useful picture material for a possible surgical intervention was obtained. The pictures always were high-grade, independently of the patient's circulation time. Because this is a simple investigation and because of the small risk of complications, it has come to be regularly carried through as a routine in the authors' clinic. According to investigations carried through on the collective of patients of a vascular surgery department, occlusions or anastomotic aneurismus account for most of the angiological disorders. (orig.)
