May–Thurner syndrome is a common condition in which there is compression of the left pelvic veins causing obstruction in venous inflow; leading to the left lower extremity causing discomfort, swelling, or blood clots called deep venous thrombosis (DVT), in the pelvic veins.This condition also causes development of varicose veins in the affected leg
Management of underlying defect may require angioplasty and stenting of the iliac vein. A stainless steel mesh called stent is used support the vein followed by balloon procedure to reestablish the flow. Post procedure patient is required to take blood thinners for period of six to twelve months. The varicose veins disappear after the blockage in the Iliac veins is resolved.
