Carpal tunnel syndrome is a common peripheral nerve entrapment neuropathy caused due to compression of the median nerve at the level of the wrist joint. Bifid median nerve associated with a persistent median artery is a rare entity and in itself asymptomatic anatomical variant. However, distension of the persistent median artery due to a thrombus can be symptomatic due to compression on the median nerve and can compromise the blood flow to the palm. We report a case of persistent median artery thrombosis in a young female patient who presented with symptoms of carpal tunnel syndrome diagnosed on the ultrasonography and confirmed on the MRI with subsequent improvement post anticoagulation therapy.
腕管综合征是一种常见的周围神经卡压性神经病变，由正中神经在腕关节水平受压引起。与持续正中动脉相关的双叉正中神经是一种罕见的、本身无症状的解剖变异。然而，由于血栓导致的持续正中动脉扩张可能因压迫正中神经而出现症状，并可能影响手掌的血液供应。我们报告一例年轻女性患者的持续正中动脉血栓形成，该患者表现出腕管综合征症状，经超声检查诊断，并经磁共振成像证实，抗凝治疗后症状改善。
