      RIGHT-MIDDLE AND LEFT-MIDDLE COLIC ARTERIES ARISING INDEPENDENTLY FROM THE SUPERIOR MESENTERIC ARTERY IN THE DISSECTION MATERIAL OF THE ANATOMY AND EMBRYOLOGY DEPARTMENT OF UMF TÂRGU-MUREŞ - CASE REPORT (Abstract): Introduction: Anatomical variations of the arterial supply of the abdominal organs are relatively frequent. The most variations were reported regarding the celiac trunk (CT), followed by the superior mesenteric artery (SMA) and the inferior mesenteric artery (IMA), which seems to be extremely rare. In case of the middle colic artery (MCA), multiple variations of origin and number have been described. Purpose: The aim of this study is to present the anatomical variations of the MCA based on a case report. Material and methods: We have dissected a formalin fixed male cadaver from the demonstration material of the Anatomy and Embryology Department of UMF Târgu-Mureş. Results: We have found two middle colic arteries: a right-middle and left-middle colic arteries arising independently from the SMA. The right-middle colic artery supplied the hepatic colic flexure and the right part of the transverse colon. The left-middle colic artery supplied the splenic colic flexure and the left part of the transverse colon. The middle part of the transverse colon was supplied by an arterial connection between the two mentioned arteries. Conclusions: Detailed knowledge of anatomical variations of the colic arteries is important especially during surgical and interventional radio-oncological approaches of the pathology involving the large intestine to prevent any inadvertent complication.
