Real-World Data Collection of the GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis When Used in Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB) to Treat Aortoiliac Occlusive Disease

To be included in this study, you must be an adult aged 18 or older who has already had the CERAB procedure to treat aortoiliac occlusive disease. This procedure must have involved implanting the VBX stent in the main artery (aorta) and must have taken place at least one year before the study began looking for participants. You (or your legal representative) would also need to agree to let the researchers look at your existing medical records.

However, you wouldn't be able to be part of this study if you had received another stent in your main artery or the iliac artery (a branch off the aorta) before your CERAB procedure. Also, if you had a different type of procedure called a 'chimney procedure' at the same time as your CERAB procedure, you wouldn't qualify. Finally, if you were involved in another research study that might affect the findings of this one around the time of your CERAB procedure, you also wouldn't be eligible.

If you are eligible, taking part in this study would involve allowing researchers to look at your existing medical records from your hospital visits. They will collect information that was already written down during your initial treatment, when you left the hospital, and during any follow-up appointments you've already had. This includes your visit about a year after your procedure and any visits since then. You won't need to have any new tests, take any new medication, or attend any extra appointments just for this study; everything they need will come from your past medical care. The study is about collecting information that already exists, so there are no new procedures or follow-ups required from you.
