<s>[INST] I had a ct scan and they said that I have a small spot that is thin on my aorta it is in the abdominal area and they were doing a ct scan of my chest. they want to do another ct of my abdoman to zero in on the spot is this something that sounds like I should consider doing. [/INST] Hi ! I had gone through your question and I understand  your concern.The conditions when we find thin  spot in abdominal aorta we call it  Abdominal Aortic Aneurysm.  Depending of the size of the spot you may have symptoms or no .When you start to have abdominal or back pain ,it shows that the spot is getting bigger or a rupture.A CT is used to measure the size and the anatomy of the spot  .The spot that are more than 5 -6 in diameter must be repaired less than that we keep monitoring .The thing that you should do is to quit  smoking  if you do.Check  you blood pressure,  it's important to keep it low .Less than 140/90 Check your cholesterol level  , take statins (atorvastatin) if it's high . Wish you good health.Thank you for using HCM . </s>
