Abdominal aortic aneurysm with kidney issues
My brother (62 yrs) has an AAA of size 5 cm. He is also showing an elevated level of creatinine, indicating kidney issues. His creatine level is now 4.08 (it was 2.54 four months ago). Doctors suggested endovascular stent. We received two different views from two different doctors and both are great vascular surgeons. One view that, in order minimize impact to his kindneys, stent will be performed with a minimal level of contrast (mainly CO2 based contrast). Pre-operative assessment will be done using MRA and CT without contrast. The other view that CT with contrast would be necessary for full information not only during the procedure but also prior to the procedure to assess the patient and that the risk of further damage to the kidneys are unavoidable. We are unsure about which one to go with and whether the first one could mean any risk of inaccurate fit of the stent due to potentially less accurate information. Any views or thoughts would be appreciated. Thank you!
