[Angiographic research on the blood supply of the colon with a view to oesophagoplasty (author's transl)].

The author presents an angiographic study of 34 cadavers concerning the colonic vessels, and draws up an original classification of colonic vessels which arise from the inferior mesenteric artery. He found 16 variants of the left colonic artery which he groups into 5 main types, the classical type being only encountered in 22.6 p. cent of cases. In 32 p. cent, the ascending and descending branches of the left colonic artery had a separate origin from the inferior mesenteric artery. The variants of the sigmoid arteries and of the left colonic veins were also identified. In one case, the inferior mesenteric vein was absent, being supplanted by the marginal vein. As for colo-oesophagoplasty, the isoperistaltic transverse colon was found to be better than the ileo-colon in 64 p. cent of cases and equivalent in 20 p. cent. In 16 p. cent the ileo-colon was preferable. The site of the arterial sections in colo-oesophagoplasty according to the colonic vascular type is discussed.
