Open surgical treatment for postthrombotic syndrome.

The postthrombotic syndrome counts as a frequent long-term complication after deep vein thrombosis with approximately 20%-50% of affected patients after deep vein thrombosis. The earliest that diagnosis of postthrombotic syndrome can be made is 6 months after deep vein thrombosis. Most patients suffer from swelling and chronic pain. In all, 5%-10% of patients may even develop venous ulcers. The complex etiology consists of limited venous drainage because of chronic occlusions and secondary insufficiencies of venous valves inducing non-physiological venous reflux. Conservative management, first of all compression therapy, is of crucial importance in treatment of postthrombotic syndrome. Endovascular and open surgical techniques can additionally be used in a small subgroup of patients. Although rarely performed, this article illuminates the open surgical techniques in treatment of postthrombotic syndrome such as venous bypass surgery, valve repair and varicose vein surgery.
