Arterial variations in upper limbs are often reported commonly. Superficial arterial variations accounting for 4.2% of all arterial variations are hazardous during any invasive procedures of the upper limb, from routine intravenous injections to surgeries. Arterial variations are usually associated with inverted or absent palmaris longus. Palmaris profundus, a rare anomalous variation of palmaris longus has been reported in carpal tunnel syndrome as its tendon was associated with median nerve in the carpal tunnel. The authors reported a unique variation in the upper limb arterial pattern-the presence of bilateral superficial brachioulnar artery associated with unilateral palmaris profundus muscle and an abnormal radicle of musculocutaneous nerve to the median nerve in the left side.
上肢动脉变异经常被普遍报道。占所有动脉变异4.2%的浅表动脉变异，在从常规静脉注射到手术等上肢的任何侵入性操作过程中都是危险的。动脉变异通常与掌长肌倒置或缺失有关。掌深肌是掌长肌一种罕见的异常变异，在腕管综合征中已有报道，因为其肌腱与腕管内的正中神经有关。作者报道了一种上肢动脉模式的独特变异——双侧肱尺浅动脉存在，伴有单侧掌深肌，以及左侧肌皮神经至正中神经的异常分支。
