May-Thurner Syndrome: Case Report and Literature Review

Abstract

May-Thurner Syndrome (MTS) is a rare clinical condition that is more prevalent in women and consists of compression of the left common iliac vein by the right iliac artery.¹ The objective of this study is to report a case of MTS showing the relation with thrombotic events and perform a literature review. The etiology is categorized as multifactorial and is associated with clinical manifestations related to venous hypertension: pain, edema, varicose veins in the left lower limb, superficial venous reflux, post-thrombotic syndrome and primary lymphedema.^3,4 The classification occurs according to the appearance and severity of symptoms, the last stage being the appearance of deep venous thrombosis in the left lower limb, which is most frequently affected.^3,6 The diagnostic approach is initially performed through anamnesis and physical examination, with the request of complementary tests such as computed tomography, magnetic resonance imaging and venography being important.^1,3,4 The treatment does not have a specific guideline, but considering the clinical condition it can be done through anticoagulant compressive stockings, balloon angioplasty or stent placement.⁷
