BACKGROUND
May-Thurner anomaly is characterized as external venous compression by the arterial framework against hard bony structures. This chronic anatomical lesion infrequently leads to deep vein thrombosis in the lower extremity, and it may lead to leg swelling as a long-term post-thrombotic complication. Left iliac vein compression may not be as uncommon as was previously thought, and it typically occurs in women more than men. Congenital anomalies of venous tree are not rare; they exist in 8.7% of the general population.
CASE-PRESENTATION: We herein present the first case of right-sided May Thurner Syndrome in a patient with IVC anomalies. In our patient, both common iliac veins formed the left-sided IVC, which extended to the hemiazygos vein and the superior vena cava. Additionally, there was a right-sided suprarenal IVC, which extended to the right atrium.
CONCLUSION
Understanding the proper anatomy in May-Thurner syndrome helps in better decision making for management of disease pathophysiology.
背景
May-Thurner 异常的特征是动脉结构对坚硬骨质结构造成外部静脉压迫。这种慢性解剖学病变很少导致下肢深静脉血栓形成，并且可能作为长期血栓形成后并发症导致腿部肿胀。左髂静脉受压可能并不像以前认为的那样罕见，而且通常女性比男性更易发生。静脉系统的先天性异常并不罕见；在普通人群中占 8.7%。
病例介绍
我们在此呈现首例患有下腔静脉异常的右侧 May-Thurner 综合征患者。在我们的患者中，双侧髂总静脉形成左侧下腔静脉，其延伸至半奇静脉和上腔静脉。此外，存在一条右侧肾上腺下腔静脉，其延伸至右心房。
结论
了解 May-Thurner 综合征的正常解剖有助于更好地对疾病病理生理学的管理做出决策。
