Endovascular stent placement for malignant stenosis and occlusion of the bilateral iliac veins and inferior vena cava after failure of radiation therapy.
A 70-year-old woman with advanced ureteral carcinoma was referred due to stenosis and occlusion of the bilateral iliac veins and inferior vena cava after failure of radiation therapy. We successfully placed endovascular stents in the bilateral iliac veins and the inferior vena cava. The stents remain patent after five months of follow-up without requiring secondary intervention. As far as we know, this is the first report of radioresistant malignant stenosis of the bilateral iliac veins and the inferior vena cava that was successfully treated with stent placement.
