Operative management of greater saphenous thrombophlebitis involving the saphenofemoral junction.

Forty-three consecutive patients with greater saphenous vein (GSV) thrombosis extending to the saphenofemoral junction (SFJ) were treated. Twenty-three patients had extension of thrombus into the common femoral vein (CFV). Twenty patients had thrombus extending to but not within the CFV. Symptoms, risk factors, and physical examination were not predictive of CFV thrombus extension. When compared with the operative record, duplex scans accurately located the extent of the thrombosis 100% of the time. Forty-one surgical procedures were performed. No patients had pulmonary emboli during the procedures. Thirty-seven patients were treated as outpatients or were discharged within 3 days of their surgical procedures. The two patients who did not undergo operative procedures in this series had complete occlusion of the CFV with extension into the external iliac vein. Thrombus within 3 cm of the SFJ is an indication for surgical intervention. Disconnection of the GSV from the CFV prevents extension of the thrombus, and a limited CFV thrombectomy can be performed when necessary. This is considerably more cost-effective than treatment with anticoagulation.
