Filter by:Proximal type 1A endoleak is a worrying complication after endovascular repair of an abdominal aortic aneurysm (EVAR). The ideal solution is not obvious between relining by FEVAR and endograft explantation. A retrospective french multicentric study was performed between 2010 and 2023 to compare the outcomes and the efficiency of both technics and propose a decision algorithm for the management of type 1A endoleak after EVAR.
The purpose of this study is to assess the extent of thrombosis in the Zenith Alpha Spiral-Z® stent graft.
Multicentre prospective registry including consecutive patients undergoing Percutaneous Endovascular Aneurysm Repair (PEVAR), Percutaneous Endovascular Thoracic Aneurysm Repair (PTEVAR) or Transcatheter Aortic Valve Implantation (TAVI) in which variables related to the percutaneous access closure for implanting devices at aorta level will be collected and analyzed. The follow-up period will be 30 days after the procedure. The duration of the recruitment period will be one year. All data will be collected telematically and incorporated into a database for subsequent statistical analysis. There will be 2 points for data interim analysis at 6 and 12 months after initiation of the study.
The purpose of this study is to investigate the short to mid term efficacy and safety of Thoracic Endovascular Aortic Repair (TEVAR) in patients who had aortic lesions, such as descending aortic/arch aneurysm, pseudo-aneurysm, Stanford Type B dissection, dissection with primary tear located in the aortic arch, et al.
The purpose of this study is to investigate the short to mid term efficacy and safety of different hybrid operations who had complex aortic lesions, such as ascending aortic/arch aneurysm, pseudo-aneurysm, Stanford Type A dissection, retrograde Stanford Type B dissection, dissection with primary tear located in the aortic arch, et al.
The purpose of this study is to investigate the short to mid term efficacy and safety of a newly-developed branched stent graft in patients who had complex aortic lesions, such as ascending aortic/arch aneurysm, pseudo-aneurysm, Stanford Type A dissection, retrograde Stanford Type B dissection, dissection with primary tear located in the aortic arch, et al.
2. Purpose of the Study - 1. To determine the feasibility of Clevidipine use for rapidly achieving and maintaining individually specified patient BP target ranges in the pre and postoperative periods of aortic aneurysm and dissection management. 2. To determine the safety of Clevidipine use in the pre and postoperative periods of aneurysm and dissection management 3. Background & Significance - Surgical treatments for persons with aortic root/arch dissection or aneurysm have significantly improved survival. However, critical in management of these patients is precise control of blood pressure (BP). With increasing BP, both acute and chronic, the risk of fatal and nonfatal vascular complications is imminent. Similarly, with excessive lowering of arterial pressures, cerebral, spinal cord, cardiac, and renal ischemic hypoperfusion is also noteworthy. Typically, the target systolic blood pressure range for these patients is 100-120 mmHg. Several different classes of vasoactive agents are in current use to acutely manage BP but none possess the optimal profile of an ideal vasodilator. Notable limitations include inadequate potency, slow onset and offset of action, multiple receptor function, safety concerns and, importantly, restricted/ineffective titration, which results in clinically significant hemodynamic and cardiovascular perturbations. Recently, the ultra short-acting intravenous dihydropyridine calcium-channel blocker clevidipine (Cleviprex, The Medicines Company) was approved for management of BP in critical care settings. Clevidipine's pharmacology lends itself to acute management of BP in a broad critical care setting in both surgical and nonsurgical patients. In the current study, the investigators propose to further characterize the hemodynamic effect of CLV in the pre and post-operative management of BP in patients with aortic aneurysm/dissection. 4. Design & Procedures Eligible patients will be approached to participate in the study by the Intensive Care Unit (ICU) attending and/or by a cardiothoracic surgical/anesthesiology fellow or a cardiac research nurse. All aspects of clinical management and monitoring will be according to standard practice that includes: - ECG - Oxymetry - Temperature - Invasive arterial blood pressure - Recording of routine laboratory results - Imaging studies including CT/MRI (A)/ Echocardiography - Pulmonary artery catheter (postoperative patients) - Mechanical ventilation (postoperative patients) - According to established protocol for acute intravenous management of arterial blood pressure in these patients, an upper and lower threshold of systolic blood pressure will be prescribed by the attending physician (the range being (100 mmHg -120 mm Hg SBP). Hemodynamic data will be collected continuously via a bedside laptop as well as pertinent clinical data and information about efficacy and safety will be recorded. • Subjective evaluation of efficacy of CLV (questionnaire format to be completed by the critical care team)
