[The post-thrombotic syndrome and its endovascular treatment].

Post-thrombotic syndrome (PTS) is a complication after deep venous thrombosis, causing considerable disability in affected patients. In this review, we present the aetiology, pathophysiology, risk factors and diagnosis of PTS and discuss different treatments with a special focus on endovascular treatment for iliac vein obstruction, which is documented as a safe, effective and durable treatment for severe PTS. Although treatment of PTS in Denmark currently only is based on conservative strategy, we would like to encourage, that endovascular treatment should be considered as a treatment option in these patients.

Calcified in-stent restenosis in a venous stent.

Stenting of the iliac veins has been an established treatment for improving venous runoff from the legs after thrombolysis of iliofemoral deep venous thrombosis for more than a decade, yet little is known about the long-term fate of stents in the central veins. We describe a case of heavily calcified in-stent restenosis in a 10-year-old venous stent as well as a way of treating this rare condition. With growing numbers of venous stents reaching a significant age, a need for treatment of long-term complications like the one presented here most probably will arise.
