Color Doppler U/S vs MSCT Venography in May-Thurner Syndrome

Overview

May-Thurner syndrome is the result of compression of the left common iliac vein between the right common iliac artery and overlying vertebrae. In This Study , We will detect the role of color doppler US in the diagnosis of May-Thurner Syndrome in comparison to Direct CT Venography

May-Thurner syndrome (MTS) is a venous compression syndrome in which the left common iliac vein is compressed between the lower lumbar spine and the right common iliac artery. While asymptomatic compression is very common, the process can lead to morbidity in selected individuals, most commonly deep venous thrombosis (DVT) and the sequelae thereof. Radiologists must recognize the diagnosis because of the unique management, which differs from DVT without iliac vein compression. The most common clinical presentation is unilateral leg swelling due to acute DVT. It can also present as chronic venous insufficiency or chronic thrombosis with symptoms of venous hypertension and venous stasis namely claudication, pain, swelling, varicose veins and / or ulceration. Conventional invasive catheter venography remains the gold standard for diagnosis,but the decision to undertake invasive venography should be made only after reviewing all available clinical data and alternative, less invasive imaging options have been exhausted. When visualization of the common iliac veins is possible, MTS may be diagnosed with transabdominal color Doppler U/S. MDCT with IV contrast is a fast, widely available examination for the diagnosis of MTS and accompanying complications . Magnetic resonance imaging (MRI) with MR venography is an attractive modality for the diagnosis, However, MRI is expensive, time consuming, has more limited availability than computed tomography (CT) and ultrasound, and may be impossible in select patients.
