[Recanalization techniques for venous outflow obstruction].

Deep vein thrombosis (DVT) is associated with a high cost burden for health care systems because of secondary cost intensive complications like pulmonary embolism and especially the post thrombotic syndrome (PTS). The current standard therapy of anticoagulation for DVT therapy has not changed through the years leaving patients especially with iliofemoral vein thrombus on a high-risk situation for developing PTS. Current study situation for endovascular treatment of iliofemoral DVT treatment gives a rationale for active thrombus removal using catheter directed therapy (CDT) or pharmacomechanical thrombectomy (PMT) which improves valvular vein function and luminal patency reducing the potential complication of PTS. For patients with chronich obstruction of the iliac vein system dedicated venous stents and recanalization techniques are today available. © Georg Thieme Verlag KG Stuttgart · New York.
