Nectero EAST System Retreatment Study

This is an exploratory pilot study to evaluate the safety and clinical utility of retreatment with an investigational combination product called the Nectero EAST System to treat Abdominal Aortic Aneurysms or AAA.

Endovascular AAA Intervention Using the GORE® EXCLUDER® Conformable AAA Endoprosthesis or Iliac Branch Endoprosthesis

A prospective, observational post-market registry collecting outcomes through a 10-year post procedure follow-up for patients treated with the GORE® EXCLUDER® Conformable AAA Endoprosthesis (EXCC Device) or the GORE® EXCLUDER® Iliac Branch Endoprosthesis (IBE Device) as a part of routine clinical practice.

Targeted Abdominal CT in Conjunction With Lung Cancer Screening

Early detection through screening can improve cancer survival by identifying it when it's most treatable. The NHS now offers Lung Cancer Screening (LCS) assessments to people aged 55-74 who have ever smoked. Those at higher risk of lung cancer are offered a lung scan. This group also has a high risk of developing abdominal cancers, such as kidney cancer. A recent study explored whether it would be feasible to extend the lung scan to include the abdomen. Results showed most participants supported this addition, and the number of serious findings was similar to those detected in UK breast or bowel cancer screening programmes. However, the abdominal scan was only offered on the day of the lung scan, giving little time for people to consider their decision. The process also added too much time to be practical for widespread implementation. This new study will: * Test whether mentioning the possible abdominal scan in the initial LCS invitation affects participation in LCS assessments. * Test new processes to assess if the abdominal scan can be added to the lung scan with minimal extra time. * Check if participants can be split between the lung scan only group and lung and abdominal scan group using an approach called 'cluster randomisation'. This will be important in case a bigger trial is needed. * See whether the additional processes are acceptable People aged 55-70 who are invited to the lung cancer screening will be eligible to take part in this study. Only those who are found to be at a high risk of lung cancer after their assessment, and therefore offered a lung scan, will be offered the abdominal scan, provided they have not had an abdominal scan in the previous 12 months or one booked in the next 3 months. This study will take place in two existing lung cancer screening locations in Yorkshire.

Endurant CHevAr New Indication Trial: ENCHANT

The purpose of the post-market study is to assess the clinical outcomes, safety, and performance of the Endurant Chimney Graft Technique (Endurant Stent Graft Systems used with a balloon-expandable covered stent graft) for treatment of juxtarenal aortic aneurysms with a short infrarenal neck in a real world setting.

JAGUAR Trial: ObJective Analysis to GaUge EVAR Outcomes Through Randomization

Prospective, randomized, multi-center study designed to evaluate the outcomes of commercially available contemporary EVAR in a real-world population. Patients will be randomized into two device cohorts and compared across the primary endpoints. Patients will be followed procedurally to discharge, at 1, 6, 12 months and annually through to 5 years (total follow-up commitment).

Virtual Prehabilitation for Patients Undergoing Abdominal Aortic Aneurysm Repair

The time between diagnosis and operative intervention represents an untapped opportunity to optimize patient readiness for surgery and augment their function prior to undergoing a physiological stress, rather than purely recovering post-operatively. Vascular surgery patients are frail and primed to benefit from such interventions and upcoming surgery is a strong motivator for behavioral change. In this proposal, the investigators outline our vision for a prehabilitation program for patients undergoing elective open aortic aneurysm repair (AAA). Participants scheduled to undergo AAA repair would receive, in addition to standard of care, 5 main interventions: exercise therapy; smoking cessation counseling and pharmacotherapy; nutritional counseling; psychological readiness planning and patient education. Exercise therapy will consist of 6 weeks of moderate exercise coordinated remotely through the cardiology rehabilitation program, whereas all other interventions will be consultations through videoconferencing or phone interactions. Outcomes of interest include morbidity, mortality, predictors of completion of program, exercise function and quality of life. This study is a pilot feasibility project and the first step in the creation of a long-term program that will improve patient clinical outcomes, exercise capacity quality of life and hopefully become an model for prehabilitation for other institutions across the country and raise the standard of care for vascular surgery patients.

Prediction of Abdominal Aortic Aneurysm Shrinkage After Stent-placement With Artificial Intelligence

The goal of this observational study is to find out what factors contribute to a good treatment outcome in patients who have received a stent for their dilation of the main abdominal artery (abdominal aortic aneurysm or AAA). The primary goal of this study is to build a prediction model for abdominal aortic aneurysm shrinkage one year after the treatment.
