The ulnar artery is the larger terminal branch of the brachial artery. It originates in the cubital fossa and is covered by the flexor muscles of the forearm. We report an anatomic variant in which the ulnar artery was in a superficial position in the forearm. Since this variant was unknown, an attempted venous puncture injured the artery, causing formation of a pseudoaneurysm.
尺动脉是肱动脉较大的终末分支。它起自肘窝，被前臂的屈肌覆盖。我们报告了一种解剖变异情况，即尺动脉在前臂处于浅表位置。由于这种变异不为人知，一次静脉穿刺尝试损伤了该动脉，导致假性动脉瘤形成。
