Inferior vena cava reconstruction using fresh inferior vena cava allograft following caval resection for leiomyosarcoma: midterm results.

We present a 56-year-old woman affected by a large leiomyosarcoma originating from the suprarenal inferior vena cava (IVC). A computed tomography (CT) scan revealed near obstruction of the IVC and involvement of the right renal vein. The patient underwent successful en bloc resection of the tumor, right kidney, right adrenal gland, and IVC.

Successful treatment of endotension and aneurysm sac enlargement with endovascular stent graft reinforcement.

Abdominal aortic aneurysm (AAA) enlarges after successful endovascular repair because of endoleak, which is persistent blood flow within the aneurysm sac. In the absence of detectable endoleak, AAA may still expand, in part because of endotension, which is persistent pressurization within the excluded aneurysm. We report three patients who underwent successful endovascular AAA repair using the Excluder device (W.
