The suprascapular artery (SSA) has been identified to be of clinical relevance to clavicular fracture, suprascapular neuropathy and surgical intervention of shoulder. Thus its origin and course have been intensively studied. In this case, we found a unilateral variation of the suprascapular artery, originating from the 1st segment of axillary artery, and sequentially penetrating the upper trunk of brachial plexus, passing through the suprascapular notch under the superior transverse scapular ligament. This case will be helpful to clinical management in cervical and shoulder region.

KEY WORDS: Suprascapular artery; Variation; Axillary artery.
