How Long Might Recoveries Continue After Very Severe Brain Injury?

Background: May-Thurner Syndrome (MTS) is aniliac vein compression syndrome which results in a thrombosis of thecommon left iliac vein. The main cause of this compression is the overlying right common iliac artery.Method: In this article we describe the case of a 35-year-old woman with bilateral lobar pulmonary embolism (PE) togetherwith an investigation of the risk factors leading to PE. The final diagnosis was a MTS with asymptomatic left internal veinthrombosis, further complicated by a PE.Results: Precipitating factors were polycystic ovarian syndrome, combined oral contraceptives and a possible protein Sdeficiency.Treatment encompassed anticoagulation during the first year of treatment. Re-evaluation together with furtherretesting of protein S and imaging will determine the need for an endovascular approach to the iliac vein compression. Inthis article we discuss the diagnostic approach to patients with PE with an asymptomatic deep venous thrombosis.Conclusions: This article seeks to draw attention to MTS as an incompletely studied syndrome which is potentially frequentin female patients with PE and interacts with other factors to increase the risk of a thrombosis. MTS should be consideredin the differential diagnosis of a patient with PE in addition to patients presenting with a proximal deep venous thrombosis.
