Filter by:That the full-moon stage of the lunar cycle is associated with reduced mortality and shorter length of stay in patients undergoing repair of aortic dissection, after adjusting for seasonal effects, demographics and cardiovascular risk factors.
Few data exist on gender-related differences in clinical features, management, and outcomes of acute aortic dissection (AAD) in China. Accordingly, we enrolled 2015 patients with AAD from 15 hospitals in China to access differences in clinical features, management and outcomes between men and women. in this study, our results provided new insights into gender-related differences in clinical features, management and outcomes in the Chinese patients with AAD. Important implications may be helpful to improve diagnostic and therapeutic outcomes.
The objective of this study is to assess the benefits of endovascular technique in terms of efficacy and safety of Valiant Thoracic Stent Graft with the Captivia Delivery System in the treatment of thoracic aortic disease, in a cohort of patients representative of the population treated under real-life conditions of use in France for up to 5 years.
The TRANSFIX study is a clinical trial approved by US FDA to study the safety and effectiveness of the Zenith® TX2® Low Profile Endovascular Graft for treatment of Blunt Thoracic Aortic Injury.
The Zenith® Dissection Clinical Trial is a clinical trial approved by US FDA to study the safety and effectiveness of the Zenith® Dissection Endovascular System in the treatment of acute, complicate Type B aortic dissection.
The purpose of this study is to determine if the Valiant stent graft is safe and effective in treating patients who have a thoracic dissection. A thoracic dissection is a tear in the wall of the aorta, that causes blood to flow between the layers of the aorta and force the layers apart (dissect). This condition is a medical emergency and can quickly lead to death. 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 device would be effective in treating dissections. Information will be collected on the performance of the device for 5 years.
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.
The purpose for this study is to determine if surgery (repair of descending thoracic aneurysm) causes a temporary decrease in the Blood Brain Barrier's ability to remove drugs from the brain back into the blood. The Blood Brain Barrier surrounds the brain and the spinal cord. This Blood Brain Barrier acts as a filter and allows some things to cross into the brain and allows other matter to be removed. Studies have shown the Blood Brain Barrier is affected by inflammation. Functions of the Blood Brain Barrier in animals have been studied. Human studies with multiple causes of inflammation (e.g. Alzheimer's, Epilepsy, trauma and severe infections in critically Hypothesis: Surgically-induced inflammation will temporarily reduce blood-brain barrier drug efflux transporter function in proportion to the degree of inflammation. The investigators anticipate that inflammation-mediated reductions in drug transporter function will be reflected by an increased cerebral spinal fluid (CSF) concentration of morphine (a PGP substrate) and M3G and M6G (MRP1 substrates). The corresponding in vitro studies will allow us to elucidate the mechanism(s) by which inflammation alters blood brain barrier efflux transport of morphine, M3G and M6G.
Study Type: Interventional Study Design: Treatment, Open Label, Uncontrolled, Single Group Assignment, Safety and Efficacy study Official Title: A Clinical Study of the TAG Thoracic Endoprosthesis in the Treatment of Thoracic Aortic Diseases for Non-Surgical Candidates under the Physician Sponsored IDE. PURPOSE OF RESEARCH: You are invited to participate in a research study for treatment of aneurysms of the descending thoracic aorta. The investigational device, called the TAG Thoracic Endoprosthesis (device) has been designed to simplify treatment of aneurysms of the descending thoracic aorta. The other pathologies treated can include pseudoaneurysms, acute and chronic dissections, penetrating ulcers, mycotic aneurysms, ruptures, fistulae, and transections.The device is made from a graft (an artificial vessel) which is surrounded on the outside by a metal mesh-like form. The device is in the shape of a tube. The device reinforces the weakened part of the aorta from the inside. Blood flows through the device to the arteries that go to your abdomen and legs. The device is folded tightly onto a catheter (a flexible, hollow tube) that is put into the aorta through an artery in your leg. Unless there is a problem, you would not need to have your chest opened.
This study was designed to study safety and effectiveness of the Valiant Thoracic Stent Graft to treat thoracic aortic aneurysms.
