The purpose of this study is to determine if the Valiant stent graft is safe and effective in treating patients who have a blunt thoracic aortic injury (BTAI). BTAI is when the aorta has been injured due to traumatic force to the chest area. It is commonly caused by motor vehicle accidents. In most cases it is life threatening and the standard treatment is surgery. Many times when a person has a BTAI they also have other injuries that can affect the results of the surgery.
Since stent grafting has been an effective way to treat other aortic conditions such as aneurysms (bulge in aorta wall), it is believed that the Valiant stent graft would be effective in treating BTAI. A stent graft is a woven polyester tube (graft) supported by a metal frame of strong but flexible nitinol (type of metal) springs (stent) that is placed in the aorta to help seal the injury and keep it from bleeding.

To evaluate the safety and feasibility of a novel stent-graft for thoracic endovascular aortic repair (TEVAR) in a canine model, 9 adult hybrid dogs were used for the experiment.
The aim of this retrospective study was to examine the impact of graft oversizing on gutter area and stent compression in chimney graft (CG) for complex abdominal aortic aneurysms (CAAA) repair. The i...

Aortic stent-graft infection is rare, but remains one of the most challenging and threatening complications. This systematic review aimed to identify the clinical features, treatment and outcomes of e...
The immune responses of a host to a graft. A specific response is GRAFT REJECTION.
An immunological attack mounted by a graft against the host because of tissue incompatibility when immunologically competent cells are transplanted to an immunologically incompetent host; the resulting clinical picture is that of GRAFT VS HOST DISEASE.
The survival of a graft in a host, the factors responsible for the survival and the changes occurring within the graft during growth in the host.
The induction of prolonged survival and growth of allografts of either tumors or normal tissues which would ordinarily be rejected. It may be induced passively by introducing graft-specific antibodies from previously immunized donors, which bind to the graft's surface antigens, masking them from recognition by T-cells; or actively by prior immunization of the recipient with graft antigens which evoke specific antibodies and form antigen-antibody complexes which bind to the antigen receptor sites of the T-cells and block their cytotoxic activity.
The clinical entity characterized by anorexia, diarrhea, loss of hair, leukopenia, thrombocytopenia, growth retardation, and eventual death brought about by the GRAFT VS HOST REACTION.
A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
