Results obtained on 431 patients studied during thirty months (February '83-June '85) with DSA-whole body angiography are reported. On the basis of statistic evaluation, PAN-DSA certainly appears the best choice, especially with combined use of 150 mgI/ml and 300 mgI/ml contrast medium. A highly significant incidence of athero-sclerotic lesions found on target-territories, even in the presence of monofocal symptoms, suggests global radiological study (PAN-DSA) as indicated whenever diffuse vascular pathology is suspected.
