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.

Thoracic endovascular aortic repair (TEVAR) is used for treatment of thoracic aortic pathologies, but the covered stent graft can induce spinal ischaemia depending on the length used. The left subclav...
The aim of this study was to investigate the accuracy of stent graft deployment in the distal landing zone (LZ) during thoracic endovascular aortic repair (TEVAR). Currently, TEVAR focuses on accurate...
Stent graft-induced distal re-dissection (SIDR) is a burdensome complication after thoracic endovascular aortic repair (TEVAR) for Type B aortic dissection. We developed a novel method to prevent SIDR...
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.
Secondary aorto-oesophageal fistula is a rare, lethal complication occurring after thoracic endovascular aneurysmal repair. The cause of secondary aorto-oesophageal fistula is unknown, but a reduction...
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. &...
Anxiety is caused by stress. It is a natural reaction, and is beneficial in helping us deal with tense situations and pressure. It is deterimental when is becomes an excessive, irrational dread of everyday situations. The most common types of anxiety di...
