Why the study?
Inferior vena cava aneurysms are rare abnormalities that can occur from the infrahepatic to suprahepatic segments.
Percutaneous thrombectomy and stenting can be a successful management strategy for thrombosed IVC aneurysm and stenosis.
May support endovascular stenting in rare thrombosed IVC aneurysms; leaves open need for prospective data on durability.
Inferior vena cava (IVC) aneurysms are rare abnormalities, typically classified as saccular or fusiform, that can occur from the infrahepatic to the suprahepatic IVC segments. We present a case of thrombosed IVC aneurysm and stenosis near the hepatic veins (Gradman and Steinberg type II) associated with extensive venous thrombosis involving the IVC and iliac veins. Our patient was successfully managed with thrombectomy and stent placement, with subsequent venous patency and reduced size of the thrombosed aneurysm observed at 2-month follow-up.
