CT scan frequency
Hi there,
For those TTA 'watch and wait'', how often you have a CT scan ?
Is every 6 months a high risk of radiation for the body?
Thank you , take care everyone. I am at 4.5 cm currently
Interested in more discussions like this? Go to the Aortic Aneurysms Support Group.
For a thoracic aortic aneurysm measuring 4.5 cm, it is generally recommended to have a CT scan every 6 months. This frequency allows for close monitoring of any changes in the size or shape of the aneurysm, which is crucial in determining the appropriate timing for any potential intervention. I have a transplanted aortic graft made of dacron. I'm at 4.1 cm and I get an annual CT, with contrast every other time to lessen the kidney damage. While it’s true that frequent CT scans do involve exposure to radiation, the risk of radiation-induced complications is relatively low compared to the potential risk of an undetected increase in the size of your aneurysm. The cumulative radiation exposure over several years of regular monitoring is a valid concern, but in your case, the benefits of frequent imaging likely outweigh the risks. Trust me, you want to keep a close eye on that aorta. They get one shot at fixing it and you'd better have it done BEFORE it dissects.
There are some alternative imaging techniques, like MRI, that don't involve ionizing radiation and might be suitable for long-term monitoring. However, the imaging technique you'regoingto want to use depends on a lot of factors, including the specific characteristics of your aneurysm and your overall health condition. This is a decision best made in consultation with your cardiologist or vascular surgeon. I get 8K hires imaging done at the University of Minnesota - Fulton Street Imaging. It's worth it to travel to the best imaging center in your area and have it done right. I also get a CD-ROM with all my pictures every year and look at it myself (because, well, I'm THAT guy). There is really cool free software for Windows and the MAc that allows you to reconstruct the images in 3D and look at them. I highly recommend it. The more educated you are about your body the better your odds. Your doctor will tailor the monitoring schedule to your specific case. They may also consider alternative imaging methods if they deem it appropriate, ensuring that you are monitored effectively while minimizing any unnecessary risks.
As always, you provide important information. I'm certainly going to be more assertive and proactive with my doctor because of the things you've written here.
I have a 4.7 TAA and am in a yearly CT schedule
I do not have a cardiologist and it was recommended to retest in two years. I had my first CT, with contrast almost two years ago in October and it was 4.3. I talked to my husband's cardiologist's office and they also looked at the scan and told me two years was fine. After the first scare I calmed down and begin the recommendations to start my prescribed medicines my doctor ordered (Atorvastatin and Amlodipine) and adjust to exercise limitations (which was not a big deal since I no longer went to the gym after COVID and only walked. I feel great and enjoyed three cruises which included walking quite a bit. I plan revisit if the every other year is still fine and also inquire about the "flutter instability parameter" mentioned on another thread. I feel blessed I can still enjoy life and this and my thyroid are my only health issues.
Mine was 4.5 initially and I was on a one-year schedule. The one-year measurement was larger in the ball park of .2cm and the next scan was scheduled in 6 mos.
Thank you , I just found that CT scan is the best when you need to measure the size , better than MRA. All the best for you!
I find it useful to know what other people's scores are. I'm a 4.2 and it seems there are folks with higher scores who are on a yearly schedule to be checked. I guess 5 is the magic number we don't want to reach. But I still worry that even with 4.2 I'm still at risk for something catastrophic. Every twinge causes at least a bit of alarm. Keep sharing. It helps.
I agree with you this thread helped me alot.
Pamela, what I found in my journey is that 5cm is the protocol for surgery.
Between 4.5 and 5cm is a mind game, it depends on the family history , your body surface, rate of growth, genetic factor, BAV, your personal preference for time of surgery. In this range you definitely want a 6 months follow up .
I went from a 3.9 cm to 4.3 in 10 years . Then suddenly from 4.3 to 4.5cm in one year...
I'm at 5 cm and get a yearly MRI.
I'm trying to get my weight down and get in better shape before surgery. My doctor doesn't consider surgery until 5.5 cm, the old guideline.
There is an ascending aortic stent being approved by the FDA soon that can be placed in a TEVAR procedure. It's been in use with patients who are too medically fragile for an open procedure, so the stats don't look as good. But that is kind of to be expected.
I'm trying to wait for that to get approval and see if I can get in with a surgeon who is familiar with this alternative.
