Filter by:The purpose of this study is to assess the safety and efficacy of the 31 mm GORE EXCLUDER® AAA Endoprosthesis in the treatment of infrarenal abdominal aortic aneurysms
The Phase I safety study is now complete. FDA approval has been granted to proceed to Phase II. The primary objectives of the Phase II study is to assess the safety and effectiveness of the Anaconda Stent Graft System in subjects presenting with abdominal aortic aneurysm (AAA). The secondary objectives of this study are to assess additional clinical outcomes measurements associated with treatment of AAA using the Anaconda Stent Graft System
The purpose of this study is to evaluate the performance of the GORE EXCLUDER® Bifurcated Endoprosthesis-Low Permeability in the primary treatment of infrarenal abdominal aortic aneurysms.
The role of teleradiology has far reaching implications for the health of remote and underserved populations. The ability to coordinate radiographic evaluation and diagnosis from a distance has the potential to raise the standard of patient care throughout the world. Perhaps the safest and most cost effective mode of teleradiology today is telesonography. The current project attempts to determine the extent that telesonography improves the standard of care within a rural government-run primary clinic within the Dominican Republic. The work reported herein is intended to compare the use of telesonography to the current standard of sonographic examination (referral to government hospital 60km from target clinic). The study was conducted by randomly assigning 100 patients with clinical indications for sonographic examination into experimental and control groups. Following a 60-day implementation period, the following research questions will be addressed: 1) To what extent does the use of asynchronous telesonography increase the percentage of definitive diagnoses based on the total number of scans (definitive diagnoses / total number of scans)? 2) To what extent does the use of asynchronous telesonography increase the continuity of care for patients? 3) To what extent does the elapsed time between scanning and final radiological interpretation decrease with the use of asynchronous telesonography? This study will also look at the history of telemedicine / telesonography and its dissemination into the mainstream practice of medicine, explore training protocols that may be used to assist others to establish new telesonography programs in a developing nations, and discuss both advances and persistent barriers to the implementation of telesonography programs. Hypothesis: The use of a store-and-forward telesonography system in this setting will increase the speed and number of final diagnoses per scan received by the target clinic and will increase the continuity of care by increasing the number and speed of follow-up appointments to the target clinic.
Can software be developed to automatically aid in the measurement of abdominal aortic aneurysms, and is there a way to predict future rupture or growth of abdominal aortic aneurysms.
The purpose of this study is to assess the role of abdominal aneurysm and iliac aneurysm exclusion using an endovascular prosthesis.
The purpose of the study is to evaluate the role of fenestrated/branched stent-grafts in the exclusion of abdominal aortic and thoracoabdominal aneurysms.
Endologix Infrarenal Bifurcated Stent Graft Study
The matrix metalloproteinase-9 (MMP-9) is considered to play a central role in abdominal aortic aneurysm (AAA) initiation. Doxycycline has direct MMP-9 inhibiting properties in vitro, and it effectively suppresses AAA development in rodents. Observed inhibition of AAA progression, and contradictory findings in human studies evaluating the effect of doxycycline therapy on aortic wall MMP-9 suggest that the effects of doxycycline extend beyond MMP-9 inhibition, and that the effect may be dose dependent.
Comparing 2 different anaesthetic methods during abdominal aortic aneurysm surgery. The patients will be followed up 30 days postoperative. Number of patients included will be 200. Perioperative details will be analyzed.
