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.
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.
To determine the safety and efficacy of IMPEDE-FX Embolization Plug and/or IMPEDE-FX Rapid Fill to fill an abdominal aortic aneurysm (AAA) sac outside of an endovascular aneurysm repair (EVAR) stent graft.
The primary objective of this study is to examine the safety and effectiveness of physician-modified endovascular grafts (PMEGs) for endovascular repair of complex aortic pathology in high-risk patients. The study is divided into three study arms based on the subject's aortic pathology: (1) Complex abdominal aortic aneurysm (AAA); (2) Thoracoabdominal aortic aneurysm; and (3) Aortic dissection.
The study aims to perform Endovascular Aortic Repair procedures with CO2-Angiography using a standardized an operative Protocol
The purpose of this study is to determine the long-term performance of the TREO Abdominal Stent-Graft as a treatment for patients with Infrarenal Abdominal Aortic Aneurysms or Aorto-iliac Aneurysms.
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
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.
The purpose of the study is to describe Sodium Fluoride uptake (using Positron Emission Tomography-Computed Tomography - PET-CT) following Endovascular Aneurysm Repair (EVAR) and to determine whether Sodium Fluoride PET-CT can predict the development of endoleaks.
Ten percent of the population above 60 years develops an aortic abdominal aneurysm. In case of rupture, this pathology leads to death in more than 70% of the cases. Over the past ten years, Endovascular Aortic Aneurysm Repair (EVAR) has been the most used technique for elective treatment for abdominal aortic aneurysms (AAA) in patients with a favorable anatomy. But despite excellent postoperative results with a significant reduction of mortality , a close follow-up of these patients is mandatory to detect any potential endoleaks particularly in patients with a long-life expectancy. Failed Endovascular Infrarenal Aortic Aneurysm Repair (EVAR) with development of a proximal endoleak exposes the patient to the risk of rupture and must be treated. This type of endoleaks are often related to dilatation of the proximal neck of the AAA, and of the suprarenal aorta, making the use of any aortic fixation system, or uncovered stent ineffective. In these cases, open surgical conversion with stent graft removal is possible but at the price of a significant morbidity and mortality. The alternative is the use of a fenestrated or branched stent graft (F/BEVAR) extending the proximal sealing zone to a non-diseased aorta. The goal of this study was to evaluate the technical feasibility, early and midterm outcomes of (F/BEVAR) in patients with a proximal endoleak following a standard EVAR. The investigators performed a multicentre study between January 2010 and December 2019 in 8 French University Centres which included 85 patients with 3 years of post operative follow-up.
