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: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
