ClinConnect Summary
This clinical trial, called the MAKE trial, is looking to see if using a special method with Carbon Dioxide (CO2) instead of traditional contrast dye can help protect the kidneys during a specific type of surgery called peripheral vascular intervention (PVI). This trial is especially important for patients who have peripheral vascular diseases and are at risk of kidney problems due to the use of contrast dye. The main goal is to find out if this CO2 method can prevent serious kidney issues for up to 90 days after the procedure.
To be part of this study, participants should be adults aged 18 or older who have symptoms of peripheral arterial disease and are scheduled for a PVI. They should also be at a higher risk for kidney injury based on certain criteria, such as their kidney function being below a certain level. People who have severe kidney problems, certain medical conditions, or who are undergoing specific treatments may not be eligible. If you join the trial, you will be closely monitored during your procedure and afterward to ensure your safety and health.
