PTS

This is an abbreviation for the Post Thrombotic Syndrome. It is the leg pain and swelling which occurs in many patients 6 months after a first DVT or 3 months after a recurrent DVT. Duplex ultrasound examination may reveal deep vein damage and scarring. This is seen as thickening of the vein wall with degrees of obstruction and/or deep venous reflux. If total occlusion occurs there may be collateral veins visible in the leg, pelvic region or abdomen. A CT scan may be required to assess the state of the pelvic veins and inferior vena cava which may not be seen clearly on ultrasound. Treatment consists of GEC stockings and in some patients anticoagulation to prevent recurrent DVT. Rarely, venous stenting, surgical bypass or valve repair/replacement may be required.
