Catheter-directed thrombolysis in deep vein thrombosis: Which procedural measurement predicts outcome?

The post-thrombotic syndrome (PTS) as a long-term consequence of deep vein thrombosis (DVT) is caused by a venous obstruction and/or chronic insufficiency of the deep venous system. New endovascular therapies enable early recanalization of the deep veins aiming reduced incidence and severity of PTS. Extended CDT is associated with an increased risk of bleeding and stenting of residual venous obstruction is indispensable to avoid early rethrombosis. Therefore, this article focuses on measurements during or after thrombolysis indicating post procedural outcome.
