Filter by:This study will be a cross-sectional survey of interobserver variability associated with contrast enhanced ultrasound (CEUS) to detect endoleaks using computed tomographic angiography (CTA) as the practice standard. The investigators will enroll 40 consecutive patients undergoing endovascular abdominal aortic aneurysm repair (EVAR). At the first follow-up visit after the procedure, participants will undergo two abdominal ultrasound examinations with and without contrast, and one CTA. Analyses will be conducted to examine interobserver variability in the detection and characterization of endoleaks using contrast-enhanced ultrasound (CEUS). Other endpoints include examination of sensitivity and specificity of CEUS compared to CTA, and characterization of the number and types of endoleaks detected.
The purpose of this study is to attenuate the systemic inflammatory response after Endovascular repair of abdominal aortic aneurysms, by administration of a single preoperative dosage of Methylprednisolone.
The purpose of the present research study is to investigate the pharmacokinetics, as well as safety, tolerability and pharmacodynamics of different ascending dosing regimens of AP214 in patients undergoing cardiac surgery. AP214, the investigational drug, is being developed to potentially prevent post-surgical kidney injury after thoracic aortic aneurysm repair.
Preconditioning in patients treated for elective abdominal aneurysm showed that the rate of perioperative myocardial infarction could be reduced by 80 %(ARR from 27% to 5%). Precondition where performed by 10 minutes of clamping of each iliac arteries before clamping the abdominal aorta. Human studies in cardiac patients have shown promising results with precondition. Instead of clamping arteries they have all performed the procedure by inflating a blood pressure cuff above arterial pressure on a arm. The investigators want to investigate if preconditioning induced by a blood pressure cuff on a arm can reduce the perioperative rate of myocardial infarction in patients open operated for ruptured abdominal aortic aneurysm.
The Zenith(R) Fenestrated AAA Endovascular Graft Clinical Study is a clinical investigation approved by the US FDA to study the safety and effectiveness of the Zenith(R) Fenestrated AAA Endovascular Graft in the treatment of abdominal aortic and aorto-iliac aneurysms.
The purpose of ENGAGE is to prospectively collect global 'real world' data on the Endurant Stent Graft System from AAA subjects.
The Zenith® Low Profile AAA Endovascular Graft Clinical Study is a clinical trial approved by US FDA to study the safety and effectiveness of the Zenith® Low Profile AAA Endovascular Graft to treat abdominal aortic, aorto-iliac, and iliac aneurysms.
The purpose of this study is to examine, through the endpoints established in this protocol, the long-term safety and effectiveness of the Talent Abdominal Stent Graft System, in a post-approval environment.
The Zenith TX2® Post-market Approval Study is a clinical trial approved by US FDA to further study the safety and effectiveness of the Zenith TX2® TAA Endovascular Graft in the treatment of thoracic aortic aneurysms.
The purpose of this study is to determine if it is safe and effective to use the TALENT AAA Stent Graft System as a treatment for AAAs in patients who are also candidates for conventional surgical aneurysm repair.
