Study Comparing Kidney Function After Abdominal Aortic Aneurysm Repair Using Stentgrafts With Supra- or Infrarenal Fixation

What this Trial Is About

Researchers are studying how two different types of stentgraft fixations affect kidney function after treating infrarenal abdominal aortic aneurysm AAA. The trial compares stentgrafts with active suprarenal fixation to those with infrarenal fixation. This study is a randomized controlled trial including participants from Scandinavia to understand the impact of these treatments on kidney health. Participants are randomly assigned to receive either a suprarenal or infrarenal stentgraft for their AAA. After enrollment, baseline data is collected and randomization occurs. Follow-up visits are planned at 1 month, 1 year, 3 years, and 5 years after treatment. These visits include blood tests to assess kidney function and CT scans to check the stentgraft performance. Health-related quality of life questionnaires are also completed during follow-ups. During the study, participants will undergo regular assessments including blood sample analysis for kidney function and imaging scans to monitor the stentgrafts. Researchers will measure changes in kidney function and look for new kidney infarcts as primary outcomes after 3 years. Secondary outcomes include quality of life changes, stentgraft complications, aneurysm-related events, and new cancer diagnoses. The study also monitors safety and outcomes up to 5 years post-treatment.
