Late superior vena cava perforation and aortic laceration after stenting to treat superior vena cava syndrome secondary to fibrosing mediastinitis.

We describe a case of late perforation of the superior vena cava and laceration of the ascending aorta after stent implantation for superior vena cava syndrome. The etiology of the late perforation is unclear, and could be secondary to either flaring of the trailing edge of the stent or chest trauma.
