In 114 cases of the transverse colon isolated from cadavers (50 male, 64 female), anatomical examinations of the arterial system of the colon were performed. Arteriograms were obtained after dissecting and contrasting the colonic vessels with Mixobar contrast. In one case, on arteriography of the colon with its mesentery isolated from a 55-year-old male cadaver, a rare anatomical variant was found. The third mesenteric artery originated directly from the aorta-halfway between the superior and inferior mesenteric arteries and ascended obliquely in the direction of the hepatic flexure of the colon. Supply area of the artery was typical for the middle colic branch of the superior mesenteric artery: the distal segment of the ascending colon and the transverse colon. Such a variation, although very rare, may have particular impact on diagnosis and even the method and range of surgery.
在114例从尸体分离出的横结肠标本（男性50例，女性64例）中，对结肠动脉系统进行了解剖检查。在解剖结肠血管并用米索巴造影剂进行造影后获得动脉造影图像。在1例中，从一名55岁男性尸体分离出带有肠系膜的结肠进行动脉造影时，发现了一种罕见的解剖变异。第三肠系膜动脉直接起源于主动脉——在肠系膜上动脉和肠系膜下动脉之间的中点处，并沿结肠肝曲方向斜向上走行。该动脉的供血区域与肠系膜上动脉中结肠支的典型供血区域相同：升结肠远端和横结肠。这种变异虽然非常罕见，但可能对诊断甚至手术方法和范围产生特殊影响。
