Blue toe syndrome (BTS) is an important vascular condition characterized by painful blue discoloration of one or more digits. It is frequently due to emboli and is important because of the risk of progressive ischemia and tissue loss. A 53-year-old male presented with recurrent episodes of painful blue discoloration and blistering of the skin of the right hallux. On examination, the patient was found to have a cool, blue-purple great toe; all peripheral pulses were present. The patient was investigated for coagulopathy and potential sources of emboli, but the only abnormality was significant stenosis of the dorsalis pedis artery due to extrinsic compression by the extensor hallucis brevis tendon. In the absence of any other embolic source or abnormality, we believe that this case presents a novel and potentially remediable cause of BTS and indicates the need for a careful search for an underlying lesion when common causes of BTS have been excluded.
蓝趾综合征（BTS）是一种重要的血管疾病，其特征为一个或多个脚趾出现疼痛性的蓝色变色。它常由栓子引起，由于存在进行性缺血和组织丧失的风险，所以该疾病很重要。一名53岁男性患者出现右拇趾皮肤反复疼痛性蓝色变色及水疱。检查发现，患者拇趾凉，呈蓝紫色；所有外周脉搏均存在。对该患者进行了凝血功能障碍及栓子潜在来源的检查，但唯一的异常是由于拇短伸肌腱的外在压迫导致足背动脉严重狭窄。在没有任何其他栓子来源或异常的情况下，我们认为该病例呈现了一种导致蓝趾综合征的新的且可能可补救的病因，并表明当蓝趾综合征的常见病因被排除后，有必要仔细寻找潜在病变。
