Filter by:Non-randomized studies have shown that de-airing of the delivery system with an increased volume of saline may be associated to a decrease in periprocedural stroke during thoracic endovascular aortic repair. This study is designed to provide evidence that 4xIFU-dose volume of saline flush vs. standard IFU-dose saline flush is associated to a decrease in the amount of intra-sac air detected on the first follow-up imaging after EVAR.
The aim of the study is to evaluate the effects of intermittent hypoxic-hyperoxic training (IHHT) to protect myocardium against perioperative myocardial injury during cardiac surgery using cardiopulmonary bypass.
The aim was to evaluate early and medium-term outcomes of single and double fenestrated physician-modified endovascular grafts (PMEGs) for endovascular aortic arch degenerative aneursym repair. The evolution of stent-graft technology recently has meant the development of custom-made branched stent-grafts to achieve total endovascular aortic arch repair for high-risks patients. The disadvantages of custom-made include manufacture and deliver times for urgent cases and the associated high costs. Unfortunately there is also a high rate of embolization associated with this approach probably related to the complexity of deploying a multi-branched unibody stent-graft. A further alternative is physician modified endografts (PMEGs) for zone 0 TEVAR involving the deployment of a conventional stent-graft device ex-vivo, fashioning of customized fenestrations (for supra aortic trunk) and re-constrainment into the delivery system. The authors have previously shown the feasability in vitro and they have reported their experience for arch aortic lesion. The aim of this study is to evaluate the outcomes for aortic arch degenerative aneursym repair which is the most risky procedure
This is the largest study to evaluate incidence and distribution of silent cerebral infarction (SBI) following endovascular repair for disease of the aortic arch. Also, it is the first cohort to include total endovascular arch repair and devices flushed with carbon dioxide (CO2) to prevent gaseous cerebral embolization.
Total endovascular repair of the aortic arch represents a promising option for patients ineligible to open surgery. Custom-made design of stent-grafts (SG), such as the Terumo Aortic® RelayBranch device (DB), requires complex preoperative measures. Accurate SG deployment is required to avoid intraoperative or postoperative complications, which is extremely challenging in the aortic arch. In that context, the investigators aim is to develop a computational tool able to predict SG deployment in such highly complex situations. Four patient-specific cases will be performed with complete deployment of the DB and its bridging stents in aneurysmal aortic arch. Deviations of simulation predictions from actual stent positions will be estimated based on post-operative scan and a sensitivity analysis will be performed to assess the effects of material parameters. If good agreement between simulation and reality is obtained, numerical simulations will show their ability to successfully predict the DB deployment in complex anatomy. The results will emphasize the potential of computational simulations to assist practitioners in planning and performing complex and secure interventions.
