Iliac vein compression condition, which is also called May-Thurner Syndrome, is when the right iliac artery compresses the left iliac vein causing swelling, blood clots, and discomfort. This condition increases a patient’s risk of DVT or deep vein thrombosis. In DVT, a blood clot forms and could partially or completely block the flow of blood through the vein.
The patient suffering from this syndrome faces a compressed left iliac vein due to the overlying right iliac artery. This leads to stasis or pooling of blood, which predisposes the patient to suffer from several blood clots. There are many treatment options including using stenting treatment procedure.
Stenting the affected vein in May-Thurner Syndrome prevents the collapse of the vein. But if there is a clot, the first step is to dissolve or remove the clot. Blood thinning medication will help prevent clots, but this medicine should be taken under medical supervision.
This non-surgical treatment is called pharmacochemical thrombolysis. Another non-surgical method to dissolve clots is by delivering the medication right up to the clot. The clot busting medicine is sent up to the clot by a catheter to dissolve or break up the blood clot.
After the blood clot is dissolved, the compressed vein is kept open by angioplasty, and this is maintained with the help of a stent.
Angioplasty is a non-surgical procedure which helps widen the iliac vein after the clot is dissolved. A small balloon is inserted and then inflated inside the vein to open it up and increase the flow of blood. The stent is then placed during this procedure to keep the blood vessel wide open.
The stent is a tiny metal braided mesh or tube that acts as a scaffold inside the vein. This ensures that the blood flows freely and there is no pooling. But if there is some other medical condition leading to the clotting of blood in some patients, that problem should also be addressed and resolved, to keep all venous diseases such as May-Thurner Syndrome at bay.
