    Abstract:
    PURPOSE: Occlusive iliofemoral venous thrombosis is associated with morbid short- and long-term consequences. Having been disappointed with standard anticoagulant therapy and systemic fibrinolysis, we embarked on an aggressive multidisciplinary regional approach to treat these patients, with the goals of therapy being (1) to eliminate iliofemoral venous thrombus, (2) to provide unobstructed venous drainage from the affected limb, and (3) to prevent recurrent thrombosis. METHODS: Twelve consecutive patients were treated for extensive iliofemoral venous thrombosis. Each had thrombus from their infrapopliteal veins through their iliofemoral system, and four had vena caval involvement. The conditions of 11 patients failed to improve when the patients were given anticoagulants, and prior systemic fibrinolysis failed in five patients. The treatment strategy includes catheter-directed thrombolysis with intrathrombus infusion of the plasminogen activator or operative thrombectomy or venous bypass with a permanent 4 mm arteriovenous fistula (AVF). RESULTS: Nine of 12 patients had a good or excellent clinical outcome (mean follow-up 25 months), which correlated with restored unobstructed venous drainage from the affected limb. Seven patients had catheter-directed lytic therapy attempted. In five patients the catheters were appropriately positioned, and lysis was successful. Five of the eight patients who underwent operations had successful procedures. Two of the three patients with poor operative outcomes had residual thrombus in their iliac veins or vena cava after thrombectomy (without bypass). The third patient, in whom anticoagulation was contraindicated, had an initially successful thrombectomy and AVF; however, vena caval thrombosis developed 2 months after operation. No patient had symptomatic pulmonary emboli, and routine posttreatment ventilation/perfusion lung scanning was not performed. CONCLUSIONS: An aggressive multidisciplinary regional approach to patients with obliterative iliofemoral venous thrombosis, designed to remove thrombus and provide unobstructed venous drainage, offers substantially better clinical outcome compared with systemic fibrinolysis and standard anticoagulation. Catheter-directed thrombolysis is successful if the catheter is appropriately positioned within the thrombus. Contemporary venous thrombectomy, which includes thrombus removal, completion phlebography, AVF, and cross-pubic bypass when necessary, is associated with high success rates. Failures can be anticipated and avoided in most patients.
