Open Surgical Management of Deep Venous Occlusive Disease.

Endovascular techniques have revolutionized the management of deep venous occlusive disease. Open surgery, however, is still required for cases that prove refractory to endovascular interventions. The surgical management of deep venous occlusive disease typically involves venous bypass. Preoperative planning before open venous surgery relies upon dynamic imaging to clarify the location and severity of venous obstruction, the assessment of infrainguinal reflux, and the delineation of bypass origination and target vessels. Adjunct arteriovenous fistulas and anticoagulation may improve patency rates of open surgical venous bypass. The timely recognition and management of complications improves secondary patency rates.
