title: [Angiectasis of the colon (Moore's type I angiodysplasia). One case (author's transl)].
abstract: A 60-year-old man had severe, recurrent rectal haemorrhages. Arteriography showed lesions suggestive of angiodysplasia located in the initial part of the ascending colon. Right-sided hemicolectomy was performed. Angiectasis of the colon is acquired and degenerative. It affects elderly people and is due to dilatation of the veins in the mucosa of the ascending colon. The lesions are usually too small to be detected by barium enema or colonoscopy, but arteriography of the superior mesenteric artery shows pathognomonic images. The only treatment is right-sided hemicolectomy.
