May-Thurner Syndrome
May-Thurner Syndrome, also known as iliac vein compression syndrome, is a vascular condition characterized by compression of the left common iliac vein by the overlying right common iliac artery. This compression can lead to reduced blood flow in the left iliac vein and may increase the risk of deep vein thrombosis (DVT) in the left leg.
The iliac veins are large blood vessels located in the pelvic area, responsible for returning blood from the legs to the heart. In May-Thurner Syndrome, the compression of the left iliac vein can cause a variety of symptoms and complications. Here are key aspects of this syndrome:
Causes:
The primary cause of May-Thurner Syndrome is the anatomical compression of the left common iliac vein by the right common iliac artery. This compression can lead to the development of blood clots in the left iliac vein, increasing the risk of DVT.
Symptoms:
Leg Swelling: Swelling in the left leg is a common symptom due to impaired blood flow.
Pain: Patients may experience pain or discomfort in the left leg, often along the course of the vein.
Deep Vein Thrombosis (DVT): May-Thurner Syndrome is associated with an increased risk of DVT in the left leg.
Diagnosis:
Imaging Studies: Doppler ultrasound, computed tomography (CT) scans, or magnetic resonance imaging (MRI) may be used to visualize the anatomy of the veins and arteries and assess blood flow.
Venography: A contrast dye is injected into the veins, and X-rays are taken to provide detailed images of the blood vessels.
Treatment:
Anticoagulant Medications: Blood-thinning medications may be prescribed to prevent or treat blood clots associated with May-Thurner Syndrome.
Thrombolysis: In cases where a blood clot has formed, thrombolytic therapy may be used to dissolve the clot.
Angioplasty and Stenting: A minimally invasive procedure may be performed to widen the compressed vein and place a stent to keep it open, improving blood flow.
Surgery: In some cases, surgical intervention may be considered to address the compression and improve blood flow.
The choice of treatment depends on the severity of symptoms, the presence of blood clots, and the overall health of the patient.
Ok, this is super important to say: Up to 1 of every 3 people have May-Thurner “anatomy” (artery compressing vein); that does not mean we have to treat one-third of the world. If you have been diagnosed with May-Thurner Syndrome or have symptoms suggestive of this condition, take a step back and call us for a second opinion or proper evaluation. Treatment plans are typically tailored to the individual patient’s condition and may involve a multidisciplinary approach with input from vascular specialists.
