A case of anomalous mesenteric artery is reported. The artery was incidentally cannulated during angiography of a patient with a left renal tumor. It arose from the abdominal aorta between the superior and inferior mesenteric arteries. The artery then ascended directly upwards from its origin and supplied the transverse colon replacing the middle colic branch of the superior mesenteric artery. The anomaly must be a result of a anomalous concentration of unpaired visceral arteries in the developing embryo. This type of anomaly is very rare and it would be appropriate to name the artery the middle mesenteric artery.
报道了一例肠系膜动脉异常的病例。在一名左肾肿瘤患者的血管造影过程中意外发现了该动脉。它起源于肠系膜上动脉和肠系膜下动脉之间的腹主动脉。该动脉自其起源处直接向上走行，供应横结肠，取代了肠系膜上动脉的中结肠支。这种异常必定是发育中的胚胎中不成对内脏动脉异常集中的结果。这种类型的异常非常罕见，将该动脉命名为中肠系膜动脉是合适的。
