[The arterial blood supply of the ascending colon].

The arterial blood supply of the ascending colon was studied by means of the injection technique in 10 post-mortem samples taken from children. In 9 of the 10 cases a complete marginal artery was found. It was supplied by the ileocolic artery in the region of the cecum and by the right colic artery near the right colic flexure. Accessory arteries supplying the ascending colon were infrequent. The narrow calibre of the marginal artery, together with the absence of accessory arteries, may result in a deficient blood supply to the middle part of the ascending colon. In contrast to the marginal arteries, the intramural vessels exhibited a uniform pattern of distribution.
