Complex interventional iliocaval recanalization due to plasmacytoma and cystic echinococcosis.

Post-thrombotic syndrome is common after iliofemoral vein thrombosis. Conservative therapy, mainly limited to compression and anticoagulation therapy, might not be sufficient in controlling symptoms. Interventional recanalization of the chronically occluded iliac veins is an evolving method, promising rapid relief of symptoms. Here, we present two cases of complex interventions in one patient with preceding pelvic radiotherapy due to a plasmacytoma and in another patient in whom a cava wedge resection had been performed because of cystic echinococcosis in the liver.
