May-Thurner syndrome (MTS) is a clinical condition characterized by the compression of the left common iliac vein between the overlying right common iliac artery and the underlying lumbar vertebrae. Although MTS can lead to deep vein thrombosis (DVT) and, in some cases, pulmonary embolism (PE), it remains underrecognized in clinical practice. We present a case of PE and DVT associated with MTS in a 20-year-old woman with a prolonged history of taking oral contraceptives (OCs). Initial computed tomography angiography (CTA) raised suspicion of MTS, which was further confirmed by Duplex ultrasonography. Anticoagulation therapy, along with discontinuation of OCs, resulted in resolution of thrombi in both the pulmonary and deep venous systems, with no recurrence following cessation of anticoagulation. This case underscores the importance of combining multiple imaging modalities in the evaluation of young women presenting with left-sided DVT, which eventually led to the diagnosis and proper management of MTS.
梅-图二氏综合征（MTS）是一种临床病症，其特征为左髂总静脉受到上方的右髂总动脉和下方的腰椎压迫。尽管MTS可导致深静脉血栓形成（DVT），在某些情况下还会引发肺栓塞（PE），但在临床实践中它仍未得到充分认识。我们报告一例20岁长期服用口服避孕药（OC）的女性患者发生与MTS相关的PE和DVT的病例。最初的计算机断层扫描血管造影（CTA）引发了对MTS的怀疑，双功超声进一步证实了这一诊断。抗凝治疗以及停用OC导致肺和深静脉系统中的血栓溶解，抗凝治疗停止后未出现复发。该病例强调了在评估出现左侧DVT的年轻女性时结合多种成像方式的重要性，这最终促成了MTS的诊断和恰当治疗。
