Abstract
Abdominal aortography and selective angiography of the branches, large and small, of the abdominal aorta were used systematically to establish the diagnosis in 45 consecutive cases of primary retroperitoneal tumor. No angiographic features peculiar to tumor types were elicited, probably because of the great variety of histologic material encountered. Angiography, nonetheless, proved most helpful for the surgical approach, whether radical removal or an exploratory operation with biopsy was contemplated. In 80 per cent of cases the tumor margins were demarcated, the details of the blood supply defined, and the nature, benign or malignant, correctly diagnosed.
