Blood Supply of the Large Intestine

The Pattern of Arrangements and Distributions of the Superior Mesenteric Artery in a Nigerian Population

“…The marginal arteries of the right colic and ileocolic arteries were not continuous in group C. This is similar to earlier workers who reported that the marginal artery may be discontinuous due to the ileocolic artery failing to anastomose with the right colic artery, and that the right colic artery very commonly may originate from the middle colic or ileocolic arteries (Steward & Rankin;Michels et al, 1963).…”

Anatomy of the transverse colon revisited with respect to complete mesocolic excision and possible pathways of aberrant lymphatic tumor spread

“…There is still a debate on whether this pancreaticoduodenal vein belongs to the anterior-inferior or to the anteriorsuperior arcade [23,24]. We could demonstrate that due to the aforementioned variability, The arterial blood supply of the transverse colon is also variable when compared to a highly constant ileocolic artery for the right-sided colon and a similarly constant left colic artery for the left-sided colon [25]. The right colic artery originates directly from the superior mesenteric artery in only 15 to 40 % [26,27].…”

Anatomical Variations in the Branching Pattern of Superior Mesenteric Artery in Adult Human Cadavers

“…The marginal arteries of the right colic and ileocolic arteries might not be continuous. This discontinuity was explained by Steward and Rankin [22]. Michels et al noted the ileocolic artery failing superior mesenteric, middle colic or ileocolic artery and supplying the hepatic flexure region [22].…”

“…This discontinuity was explained by Steward and Rankin [22]. Michels et al noted the ileocolic artery failing superior mesenteric, middle colic or ileocolic artery and supplying the hepatic flexure region [22]. Sonneland et al suggested that the right colic artery should be considered the major feeding vessel independent of its origin, directed to the ascending colon between the ileocaecal junction and the hepatic flexure [15].…”
