Filter by:The purpose of the registry is to evaluate the peri-operative, short-, and mid- outcomes of endovascular treatment of thoracoabdominal aneurysms with multibranched endografts via total transfemoral approach for visceral vessels cannulation using steerable sheaths
the aim of this study is to determine whether an intraoperative optimization protocol using the enhanced flow-based hemodynamic parameters of the FloTrac/Vigileo device in combination with intraoperative measurement of the sublingual microcirculation with the Cytocam-IDF device would result in an improvement in outcome in high-risk patients undergoing major vascular surgery, measured by the hospital LOS in comparison with intraoperative FloTrac/Vigileo monitoring alone. The FloTrac/Vigileo device only needs standard arterial access for enhanced, flow-based hemodynamic monitoring. It is reported to be easy to use and easy to set up and calculates the stroke volume (SV) on the basis of the arterial waveform in combination with demographic data. Cardiac index (CI), stroke volume index (SVI) as an indicator for fluid status and stroke volume variation (SVV) as an indicator for fluid responsiveness during mechanical ventilation and sinus rhythm will be continuously measured during major vascular procedures, including carotid endarterectomy (CEA), open abdominal aortic aneurysm (AAA) repair , endovascular aneurysm repair (EVAR), thoracic endovascular aneurysm repair (TEVAR) and fenestrated endovascular aneurysm repair (FEVAR).
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 our study is to analyze the early and late results in men and women who underwent ascending aortic replacement in antegrade cerebral perfusion (ACP) with mild-to-moderate hypothermic circulatory arrest. Female gender is associated with poorer outcomes after surgical aorta replacement. Data on gender specific differences after ascending aortic replacement are conflicting.
Open Abdominal Aortic Aneurysm (AAA) repair is a high-risk surgical procedure accompanied by intense endocrine and metabolic responses to surgical stress, with subsequent activation of the inflammatory cascade, cytokine and acute-phase protein release, and bone marrow activation. There is a proven correlation of surgical stress, which patients undergoing open AAA repair are subjected to, with patient outcome, morbidity/mortality, intensive care unit stay and overall length of stay. Modern general anesthetic techniques have been revised and rely on perioperative multimodal anesthetic and analgesic strategies for improved overall patient outcome. Based on this context of a multimodal anesthetic technique and having taken into consideration the international "opioid-crisis" epidemic, an Opioid Free Anesthesia-Analgesia (OFA-A) strategy started to emerge. It is based on the administration of a variety of anesthetic/analgesic agents with different mechanisms of action, including immunomodulating and anti-inflammatory effects. Our basic hypothesis is that the implementation of a perioperative multimodal OFA-A strategy, involving the administration of pregabalin, ketamine, dexmedetomidine, lidocaine, dexamethasone, dexketoprofen, paracetamol and magnesium sulphate, will lead to attenuation of surgical stress response compared to a conventional Opioid-Based Anesthesia-Analgesia (OBA-A) strategy. Furthermore, the anticipated attenuation of the inflammatory response, is pressumed to be associated with equal or improved analgesia, compared to a perioperative OBA-A technique.
The Zenith® Fenestrated+ Endovascular Graft Clinical Study will assess the safety and effectiveness of the Zenith® Fenestrated+ Endovascular Graft (ZFEN+) in combination with the BeGraft Balloon-Expandable FEVAR Bridging Stent Graft System (BeGraft) and Unibody2 for the treatment of patients with aortic aneurysms involving one or more of the major visceral arteries.
This Controlled Randomized Clinical Trial aimed at determining the effectiveness of a modified RR intervention in reducing post-operative pain and psychological symptoms in patients undergoing surgery intervention. Researches hypothesized that compared to controls patients undergoing modified RR intervention were characterized by 1. improved capability to discriminate emotions from bodily feelings; 2. reduce emotional distress; 3. reduced pain perception. Moreover, researches hypothesized that (4) these effects were maintained over time.
Minimally invasive aortic valve (AV) surgery has become widely accepted alternative to standard sternotomy. Despite possible reduction in morbidity, this approach is not routinely performed for aortic surgery. Evidence exists, however, on safety of this approach together with promising results regarding its long-term durability. The MIRAGE Registry is aimed to collect and analyse the data from multiple aortic excellence centres and to analyse them in numerous clinical scenarios.
Abdominal Aortic Aneurysm (AAA) screening and an aging population have increased the prevalence of AAA diagnoses. Small AAAs (<5.5cm) are monitored with ultrasound. Large AAAs may rupture and this is usually fatal. Surgery is considered at a crude size threshold of 5.5cm when the annual rupture risk reaches 5%. AAA size is the only predictor of growth and rupture available but growth is non-linear and some small AAAs rupture. Thus, only 1 in 20 patients treated at 5.5cm will have benefited from rupture prevention in the year following surgery, and others may miss out on life-saving surgery. This study will develop an imaging tool PETMRI with radiotracer Ga- DOTATATE with high clinical utility, to improve prediction of aneurysm growth and risk.
Design A multi-centre pilot study investigating the acceptability and adherence of a prehabilitation on patients requiring abdominal aortic aneurysm repair. Setting 3 NHS Hospital Vascular Surgery Clinics in the UK. - Imperial College Healthcare NHS Trust - Cambridge University Hospitals NHS Trust - Mid and South Essex NHS Trust Patient Population Patients referred to secondary/tertiary vascular clinic for the repair of asymptomatic infrarenal Aneurysm Intervention: Baseline (conducted face-to-face): After providing written informed consent, participants will be provided with information about the prehabilitation programme. The following data will also be collected: baseline demographic characteristics (including age, sex and ethnicity), body mass index (BMI), medical history (including time since diagnosis), current medication, aneurysm diameter, health-related quality of life (EQ-5D-5L and EQ-VAS), smoking status and psychological wellbeing (using the Hospital Anxiety and Depression Scale; HADS) and Frailty assessments( QMortality Index, Electronic Frailty Index, Rockall score). Participants will also complete a 6-minute walking test(6MWT).
