New endovascular prosthesis is promising for non-surgical treatment of TAAs
Research study shows promising results for non-surgical treatment of life threatening condition
Rodney White, MD, Chief of Vascular Surgery and Associate Chair, Department of Surgery at Harbor-UCLA Medical Center and Principal Investigator at the Research & Education Institute at Harbor-UCLA Medical Center (REI) is shedding new light on endovascular treatment of thoracic aortic aneurysms (TAAs). A life threatening condition caused by a weakening of the vascular wall of the aorta in the chest, TAAs can lead to either sudden death or death in a matter of hours if the aorta ruptures.
In an REI clinical study, Dr. White and a team of cardiovascular surgeons, radiologists and scientists have successfully treated approximately 60 patients over the last three years with thoracic aortic aneurysms, aortic dissections and other cause of acute rupture. REI and the Harbor-UCLA Medical Center hold the distinction of being the only study site in the Los Angeles area to conduct this FDA-approved Investigational Device Exemption (IDE) research. Results on the first 25 patients in this study were published in the Journal of Vascular Surgery, May 2001. Dr. White and his team are a part of a nationwide referral network that has also implanted endovascular prostheses into approximately 600 patients diagnosed with abdominal aortic aneurysms, the 13th leading cause of death in the United States.
Dr. White, a graduate of the State University of New York Upstate Medical Center, believes that this research holds much promise.
"With the development of endovascular prostheses to treat abdominal aortic aneurysms in the mid 1990s, a concomitant effort to adapt this technology to the treatment of thoracic aneurysms has demonstrated promising preliminary results with a decrease in both major morbidity and mortality being noted in many patients," he says.
The new technology also makes repair of thoracic aortic aneurysms and dissections available to patients who are not considered to be reasonable candidates for conventional surgical repair. "Although the experience is preliminary, the magnitude of the conventional surgical procedure and the decreased incidence of morbidity and mortality with endovascular repairs support further evaluation of this technology," he adds.
The Research & Education Institute at Harbor-UCLA Medical Center, located on the campus of Harbor-UCLA Medical Center near Torrance, California, is a leading independent, not-for-profit biomedical research institute with an international reputation for scientific discovery, the training of physician-scientists and the provision of community service programs. It is an affiliate of both the David Geffen School of Medicine at UCLA and the Harbor-UCLA Medical Center and has an annual budget of $58 million. The Institute traces its roots back to 1952, when researchers and physicians joined forces with the UCLA School of Medicine on the campus of what was then known as Harbor General Hospital to conduct a handful of research studies. Today, more than 1,000 research projects and clinical trials are being conducted at REI, advancing scientific understanding in order to improve medical outcomes and promote innovation in such areas as autoimmune disorders, cancer, cardiovascular disease, developmental disorders and other pediatric health problems, diabetes, infectious disease, inherited disorders, male contraception, vaccine evaluation and research, and various aspects of womens health.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
