A diagnosis of ulnar artery thrombosis should be considered when a patient reports symptoms of ulnar neuropathy, ischemia in the hand, or a mass in the hypothenar area. A history of repetitive blunt trauma to the hypothenar area is particularly suggestive of this. Ulnar artery thrombosis is possibly associated with an anomalous muscle in the Guyon's canal. The anomalous muscle in this case originated on the flexor carpi ulnaris muscle, was ulnarly innervated, and joined the flexor digiti minimi muscle distally. This patient had a history of blunt injury and a significant smoking history, thus, a causal relationship between the anomalous muscle and ulnar artery thrombosis cannot be stated with certainty.
当患者报告有尺神经病变、手部缺血或小鱼际区域肿块的症状时，应考虑尺动脉血栓形成的诊断。小鱼际区域反复钝性创伤史尤其提示这一点。尺动脉血栓形成可能与Guyon管内的异常肌肉有关。本例中的异常肌肉起自尺侧腕屈肌，由尺神经支配，远端与小指屈肌相连。该患者有钝性损伤史和大量吸烟史，因此，不能确定异常肌肉与尺动脉血栓形成之间存在因果关系。
