Scott & White Memorial Hospital uses device to revolutionize treatment of traumatic aortic injury

11.02.2010
One of first human implants of device for aortic injury in U.S. performed as part of clinical trial

Scott & White Memorial Hospital vascular surgeons Clifford Buckley, M.D., and Ruth Bush, M.D., performed one of the nation's first implants of a Next Generation Conformable GORE TAG Thoracic Endoprosthesis device for the treatment of a traumatic aortic transection as part of a national clinical trial. The goal of the trial is to gain insight into using thoracic endografts for patients with traumatic aortic transection (tear) as a less invasive alternative to major surgery.

"This is the first time this procedure has been performed on a human as part of a landmark study and is the first device being studied for traumatic aortic transection specifically," said Dr. Buckley, a professor of surgery at Texas A&M Health Science Center College of Medicine. "Because Scott & White Memorial Hospital is the only designated Level I trauma center between Dallas and Austin, TX, we're able to provide such cutting-edge care for patients with these traumatic injuries."

Traumatic thoracic aortic transections often result in death and injury to the thoracic aorta from motor vehicle accidents which account for up to 15 percent of all deaths. Patients who survive usually have small tears or partial thickness tears of the aortic wall and the aorta is at greatest risk in front or side impacts. Most blunt aortic injuries occur in the proximal thoracic aorta, although any portion of the aorta is at risk. The proximal descending aorta is at greatest risk from the shearing forces of sudden deceleration.

"Trauma patients with thoracic aortic transections often have multiple, complex injuries that increase the risk of standard surgical repair of the aorta," said Dr. Bush who is also assistant dean of graduate medical education at Texas A&M Health Science Center College of Medicine. "So, a minimally-invasive treatment option like this could provide an opportunity to care for patients who might otherwise be too sick or have injuries too serious to undergo a major operation to gain access to the aorta that often requires stopping the heart."

Endovascular procedures are less invasive than major "open" surgery and involve sealing off an aneurysm by placing the endovascular graft inside the aorta, re-lining and making a new path for blood flow. The GORE TAG thoracic endograft remains inside the aorta permanently through the use of a metal stent creating a tight fit and seal against the wall of the aorta. Endovascular repair may be performed under general, regional or local anesthesia and the procedure typically takes one to three hours. Patients commonly return to normal activity within two to six weeks after the procedure.

Dr. Clifford Buckley and colleagues were the first in Central Texas to use the Conformable GORE TAG thoracic endograft that helps reinforce the weakened aortic wall. A Level 1 trauma center is a comprehensive trauma facility, and provides the highest level of specialty care available, which meets stringent national standards of performance. Access to a comprehensive trauma center and its capability to provide definitive care for every aspect of injury is strongly associated with improving a critically-injured patient's chance of survival.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
