Case in brief
A patient had a large epithelioid hemangioendothelioma obstructing the superior vena cava and both brachiocephalic veins. A three-dimensional model was used to plan surgery. The tumor was removed en bloc, followed by venous reconstruction using a cryopreserved aortoiliac allograft.
What made this case unusual
The tumor obstructed the superior vena cava and both brachiocephalic veins, requiring extensive venous reconstruction with a cryopreserved arterial allograft.
Diagnostic / clinical pearl
For a large vascular tumor involving central veins, three-dimensional modeling can support operative planning for en bloc resection and venous reconstruction.
