What is the difference between May Thurner Syndrome and DVT? Is there a difference? Should I get a tested because both of my parents have DVT and I just started taking birth control pills, but I don't have any symptoms.

May Thurner syndrome is caused by an overlap of your iliac veins. This overlap leads to compression of the vein. This compression can slow the blood flow down in the vein which then increases the risk of blood clots (or DVT) in that vein. Birth control pills can increase your risk of DVTs. It depends on what caused your parent's DVTs as to whether you should be tested. I would recommend seeing your doctor after obtaining a good history from your parents.

You should find out why your parents both had DVTs and what caused these. If it is something genetic then yes, you should be tested. There are many inherited reasons people get blood clots. This would put you at a higher risk of developing a clot especially on birth control pills. May Thurner is when the right common iliac artery compresses the left common femoral vein and causes a clot. Unless you have unilateral leg swelling, I would not think that you have this.

A DVT is a Deep Vein Thrombosis (clot) involving a large deep vein that can develop often in a leg behind the knee as well as in the lower leg or thigh region. This can be caused by traumatic injuries, orthopedic and other surgeries, inherited and acquired coagulation disorders that increase the risk of blood clots, hormone supplements including birth control pill especially in smokers, and can rarely occur spontaneously. May Thurner syndrome is a congenital condition that classically results in compression of the left common iliac vein by the overlying right common iliac artery. This partial blockage leads to reduced venous blood flow and predisposes the individual to forming DVTs in this area.This older definition has expanded from the classic description above to a broader group of conditions known as non-thrombotic iliac vein lesions (NIVL) which can involve both right and left iliac veins. If both parents have had a history of DVTs and you are on a hormonal supplement, then it is reasonable to first have lab work to evaluate for a possible inherited clotting disorder including antithrombin, Protein C and S, Factor V Leiden and Prothrombin G20210A. With your parents DVTs, the location, frequency of clots and whether they were smokers, had surgeries near the time of their DVT or have had cancer would also be helpful in evaluating possible causes of their DVTs and your potential risk.

May Thurner Syndrome is compression of the left common iliac vein by the overlying right common iliac artery. It is a congenital abnormality and it can lead to pain or swelling in the left leg or it can cause DVT or blood clots in the left leg. DVT is a deep vein thrombosis and is when a deep vein is closed by a thrombus, often in the legs but may occur in any deep vein. if both of your parents had DVT's is a good idea to get tested for a coagulopathy. If both your parents also had May Thurner syndrome you should also get tested.

May-Thurner Syndrome is compression of the left common iliac vein in the pelvis by the overlying iliac artery. This results in partial blockage of venous blood flow out of the left lower extremity resulting in pain or swelling. Some women have pelvic pain and pain with intercourse as well due to the varicose veins which develop on the pelvis to carry the venous blood from the leg and pelvic organs around the blockage. Deep vein thrombosis is clotting within the deep veins of the legs or in the abdominal, pelvic, or chest veins. Oral contraceptives do increase the risk of DVT, especially in individuals who may have an inherited clotting disorder. It would be helpful for you to know whether either of your parents have a known clotting disorder causing their DVT. You may wish to discuss this with your OB-Gyn physician.

You should be tested for blood clotting disorders.

May Thurner syndrome is caused by mechanical compression of the left iliac vein by the right iliac artery which causes DVT of the left iliac vein / left lower extremity. It seems you have a high risk for developing DVT from your family history and birth control pills. A venous ultrasound to rule out DVT is recommended.

May Thurner Syndrome results from compression of the Left Common Iliac Vein by the Right Common Iliac Artery in the upper pelvic brim as it crosses over the vein which runs below the artery. This may result in compression of varying degrees, which may lead to occlusion of the LCIV resulting in venous hypertension of the affected limb (usually the left leg, but it can affect both). DVT can be associated with this syndrome or occur without it. DVT (deep vein thrombosis) is the development of a clot in any deep vein of the limb/s above or below the knee. May-Thurner is the compression fenomenon specific to the LCIV.

DVT is a blood clot inside a vein. May turner is compression of Left Common Iliac vein by the right Common Iliac artery.

May Thurner Syndrome is when there is compression on the iliac vein from the iliac artery. This is usually on the left. Compression of the vein can certainly cause a clot. DVT is a deep venous thrombosis which is a blood clot in the deep vein. This can occur in any deep vein.

May Thurner is the compression of one of the iliac veins in the pelvis by an iliac artery - the compressed vein can then have a DVT, but they are different problems. May Thurner is relatively rare and it is not cost efficient to screen for it. BCPs should always be used cautiously and only under a physicians supervision.
