Symptomatic occlusion of the inferior vena cava and bilateral iliac veins due to malignant seminoma: Percutaneous recanalization, thrombectomy, and stenting to restore patency

Abstract

Testicular seminoma is rarely associated with occlusive venous thrombosis. Several investigators describe percutaneous guidewire recanalization for iliofemoral vein thrombosis; however, this technique is ill-documented for occlusion of the inferior vena cava, and even less information is available on managing pervasive iliocaval obstruction. Furthermore, there is limited data on percutaneous mechanical thrombectomy for malignancy-induced venous thrombosis. We present a case of symptomatic chronic occlusion of the inferior vena cava and iliac veins following remission for metastatic seminoma, with percutaneous intervention necessitating a unique combination of sharp wire recanalization, mechanical thrombectomy, and stenting to restore iliocaval patency.
