[Intra-arterial DSA versus conventional angiography in assessing the resectability of pancreatic and periampullary carcinomas].

Fifty patients were examined to determine whether intraarterial DSA can replace conventional angiography to assess the resectability of pancreatic and periampullary carcinomas. Intraarterial DSA yielded equivalent diagnostic information in 60% of the cases. As a result of contrast-enhanced visualisation of the splanchnic veins intraarterial DSA was superior to conventional angiography in 26% of the cases, whereas in 14% intraarterial DSA provided less information due to motion artifacts.
