title: Anatomical Description and Clinical Relevance of a Rare Variation in the Mesenteric Arterial Arcade Pattern.
abstract: Solitary vascular variations of the mesenteric arteries are extremely rare and have been seldom reported in the past. The aim of this study is to emphasize the anatomical and clinical relevance of one such rare variation of inferior mesenteric artery (IMA). The current case anomaly was incidentally observed while guiding the undergraduate medical students in the dissection of the mesenteric region of the abdomen in an Indian cadaver. An Accessory left colic artery was seen to be branching off from the Inferior Mesenteric artery and further dividing into two transverse branches which took part in the formation of arterial arc for the perfusion of the transverse and the descending colon. Awareness of such aberrant branches of Inferior Mesenteric artery helps in optimal selection of the mode of treatment or operative planning. Additionally, this knowledge minimizes possible iatrogenic injuries resulting from surgeries. Moreover, surgical anatomy of anomalous branches of Inferior Mesenteric artery is extremely essential for planning and successfully executing reconstructive procedures using these branches as pedicles for the transposed part of the colon.
