title: [Studies on the angioarchitecture of polypoid colonic processes].
abstract: Portions of the colon removed at operation were studied angiographically after arterial or venous injection with a barium-gelatin mixture. The aims of the investigation were: To study the differences between tumour and inflammatory angiographic appearances and the clinical value of in vivo angiography of the mesenteric arteries. A comparison of the micro-angiographic appearances of benign and malignant polypoid lesions of the colon. Adenomas and carcinomas showed patterns which are easy to distinguish and permit classification in uncertain lesions. Pseudopolyps in Crohn's disease resemble adenomas in the early stages, but later assume features characteristic of tumours.
