Three years out from thoracic aortic aneurysm surgery, it is not typical to have had no follow-up at all. Most patients are followed closely in the first year with imaging (CT or MRI) at 3 months, 6 months, and 12 months to confirm the graft is intact and the repair is stable. After that, lifelong surveillance is generally recommended, though the interval may stretch to every 1–2 years if things look stable. This is because even if your original repair is solid, new aneurysms can develop in other parts of the aorta over time.

The graft in your chest is a Dacron or similar synthetic tube. These are designed to be permanent, and they do not “wear out” or dissolve. True leakage from the graft itself is extremely rare. What doctors watch for are problems at the attachment sites—where the graft is sewn into your natural aorta—or changes elsewhere in the aorta. That’s why surveillance imaging is so important.

It is very normal to not have wanted to know the details before surgery. Many of us go into it in crisis mode and just want it done. But now that you’re three years out, it’s important to establish follow-up. At this stage, you should absolutely have at least a CT or MRI to assess the repair and the rest of your aorta. A cardiothoracic surgeon, vascular surgeon, or cardiologist experienced with aortic disease should be following you long-term.

I went through a Type A aortic dissection myself in 2015, and I live with a Dacron graft in my chest. Like you, I didn’t ask many questions before surgery, but over time I learned that regular imaging and specialist follow-up are the key to staying ahead of problems. Knowing about it lets you be proactive rather than reactive. I get CT scan every year in November and every other year using contrast (it's hard on your kidneys). The contrast give them better definition of the structures but is not necessary every year.

Please schedule an appointment soon with your cardiologist or surgeon to re-establish care. Peace.
