Superficial Ulnar Artery Rerouted with Embryological Basis- A Case Report.

ABSTRACT

Variations in course of the arteries are well documented. Knowledge of the variation of the arterial system is important during vascular and reconstructive surgeries, in the evaluation of angiographic images. During routine anatomical dissection of upper limb ,of adult male cadaver of 55 years in Department of anatomy, SNMC, Agra, we came across a variant origin of the ulnar artery, instead of terminal division of brachial artery it arose from the brachial artery at its lower 1/3 part ,also it followed a superficial course. Brachial artery in the cubital fossa divided into radial artery and common interosseous artery, also the anterior and posterior ulnar recurrent branches arose from the common interosseous branch instead of ulnar artery. Knowledge of this variation is important for anatomist, embryologist, radiologists keep pace with new emerging variations, also for orthopaedicians, surgeons for planning appropriately operative procedures involving this region.
