The angiographic investigation of duodenal tumours (author's transl)

Abstract

The diagnosis and differential diagnosis of primary duodenal carcinomas by conventional radiological methods is difficult. Valuable information can be obtained by angiography, since primary duodenal carcinomas, unlike carcinomas of the papilla and pancreas, are characterised by the formation of pathological vessels arising from the duodenal branches of the gastro-duodenal artery. The integrity of the latter is an important differentiating feature. Exact localisation of the tumour is important in pre-operative assessment and diagnosis.
