title: Looped and Tortuous Ulnar Artery - An Erratic Unilateral Vascular Presentation in the Proximal Forearm.
abstract: Precise and detailed knowledge of possible anatomical variations of the arterial pattern in the upper extremity is vital during reparative surgery in this region. Scientific literatures witnessed several reports on variant origin and branching pattern of ulnar artery. But report on looped and tortuous ulnar artery is lacking in the literature. We report here a unique case of ulnar artery having double loop at its commencement giving it an appearance of sigmoid shape and its undue tortuous course in the forearm. Such an unusual and unpredictable variation of ulnar artery is vulnerable for life threatening hemorrhage during clinical approaches. It could also lead to misinterpretation of CT scans as presence of tumours. Awareness on such exceptional anatomical discrepancy of ulnar artery is important to clinicians, neuroradiologists and radiologists in general.
