Filter by:In this study, our primary goal is to compare whether there is any difference in the complication of using pro-seal laryngeal mask or intubation tube in bronchoscopy-guided percutaneous dilation tracheostomy procedure. Our secondary goal is to compare in terms of processing time.
Ischemia and reperfusion (I/R) injury during abdominal aortic aneurysm (AAA) repair is inevitable and may lead to postoperative multi-organ failure. Remote ischemic preconditioning (short periods of ischemia in anticipation of longer period of ischemia) may act protectively against ischemia. Studies of ischemic preconditioning in patients with AAA are conflicting. Obstructive sleep apnea (OSA) is a sleep disordered breathing syndrome which may have a protective effect against ischemia. The investigators hypothesize that I/R injury will be less pronounced in patients who have OSA and that the extent of I/R injury will inversely correlate with OSA severity. Accordingly, the aim of this study is to compare postoperative complications and markers of I/R in patients undergoing elective AAA repair who do and do not have OSA.
The 8-12 fold higher risk for sisters and brothers of patients with Abdominal Aortic Aneurysms (AAA) to develop AAA compared to persons in the population is well known in the scientific community. Recently the value of the screening program for siblings has been analyzed and is shown to be highly cost-efficient, similar to the population based screening of 65-year old men for AAA. Most importantly detection of siblings also adresses and includes women at risk. The adult offsprings to AAA patient would hypothetically bear the same risk of AAA as siblings. This has never been evaluated scientifically due to the practical difficulties in tracking the offspring and inviting them to screening at an age when they are at risk of AAA-disease. In Sweden, the unique multigeneration registry exists which could support such detection, with the possibility to track adult offspring to patients, and investigate the true contemporary prevalence in them. The DAAAD project aims at investigating the prevalence in adult offspring parallel to developing a model for such a selective screening program
Selection of the appropriate size of the device is mandatory during aneurysm treatment with a WEB. The Investigators aimed to investigate if virtual simulation with Sim&Size software may have an impact on technical, angiographic, and clinical outcomes after WEB treatment. Data from two large-volume centers were collected and compared (January 2017-January 2020). Virtual simulation was systematically adopted in one center, while conventional sizing was used in the other one. Outcomes were the duration of intervention, the radiation dose (mGy), the number of corrective interventions for inappropriate WEB size, the number of WEBs not deployed, angiographic occlusion, and complications. Univariate and multivariate linear models were adopted.
Hypothesis: Correction of preoperative anemia can reduce the need for intra-/postoperative RBC transfusions and can improve surgical outcomes.
Surgery for abdominal aortic pathology usually occurs in the setting of advanced cardiovascular disease. The repair can be relatively simple or complex with multiple steps including open repair, placing a stent with a catheter, and placing a complicated stent that allows for crossing vessels without occluding them. All these repairs require imaging follow up. The most commonly accepted tool for follow up is Computed Tomography (CT) scan which involves ionizing radiation and potentially nephrotoxic iodinated contrast. Recommendations for the time interval for follow up, as well the radiology imaging technique vary. Routine ultrasound with Doppler, CT, and MRI has all been employed utilizing various imaging protocols. Clinicians use non-contrast CT, arterial phase and delayed phase CT, ultrasound, and various combinations based on personal experience and patient pathology. Concerns over cost, potential nephrotoxicity of contrast agents and repeated radiation exposure has led to investigation of alternate imaging modalities such as contrast-enhanced ultrasound (CEUS). CEUS represents an improvement of ultrasound imaging but comparisons against CT report widely varying results, likely due to technical factors of CEUS and limitations of single-phase CTA. Contrast ultrasound has been used effectively to diagnose leaks in the aorta post repair and is without the radiation and potential nephrotoxicity of iodinated contrast. Of yet, no large prospective studies have compared CT and contrast US and no studies have looked at the more complicated staged or fenestrated repairs. This study proposes to perform a contrast ultrasound at the same time as a contrast CT using a standardized protocol. This protocol would include a non-contrast CT, angiographic CT, and a CT in a delayed phase in all patients as standard of care. We will compare the results of a contrast US with the various data derived from a three phase CT.
Patients admitted to Haukeland University Hospital with either UIA or aSAH underwent a measurement of bioelectrical impedance and body mass composition using InBody 10. Lipids and lipoproteins were collected from plasma. 60 patients in total were included in the study.
The purpose of the registry is to evaluate the peri-operative and short-, mid- and long-term outcomes of the Bard Covera Plus (Tempe, Arizona, USA) for the treatment of atherosclerotic aorto-iliac aneurysm in combination with a multibranched endograft
The purpose of this research study is to look at whether an investigational imaging agent, 64Cu-DOTA-ECL1i, used during Positron Emission Tomography (PET)/ Computed Tomography (CT) scanning, can help to identify conditions that place patients at an increased risk for AAA rupture. The study is also looking more closely at cellular, molecular and inflammatory properties of the aortic wall. Having the ability to identify markers that predict AAA progression/expansion and risk for rupture could allow the physician to manage patients in a more individualized, personal way.
The French Ministry registered the Fenestrated Anaconda ™ on the List of Reimbursable Products and Services (LPPR) by the French Health Insurance on February 2018 for a duration of 5 years, while taking up the conditions for carrying out the act recommended by the CNEDiMTS (Committee in charge of medical device review), namely the carrying out of a post-registration study for the renewal of the authorization. This renewal of registration is conditioned by the set-up of a long-term follow-up study of all patients treated with the Fenestrated Anaconda ™ in France. To do this, this study will be carried out in partnership with the Federation of Medical Specialties (FSM) and the National Professional Council (CNP) of Vascular Surgery in order to have the data necessary for the renewal of the registration of the Fenestrated Anaconda ™ from the registry called Datavasc developed by the CNP and available online on the FSM's electronic platform.
