[|Human|] ascending aorta,  I was diagnosed with enlarged aorta. its dilated at 4cm. should I consider surgery now or wait to see if it gets bigger in 6 months time!  Thank you I am a 51 year old man, with high blood pressure, controlled.  three months ago, I underwent back surgery.
[|AI|]  Hello, Thanks for writing to Chat Doctor, I am Chat Doctor. Dilation of aorta is irreversible, and it can only be treated by surgery. A vascular surgeon considers many merits and de merits while deciding for surgery, he looks at patients age, co forbids, dilation of aorta, prognosis, facilities available and local practices, so by just knowing the measurement if dilation it can not be safely advised, when exactly should you get the surgery. I would suggest you to follow what your doctor suggests you to do, yes you always have option to take second opinion but always get it after meeting the doctor in person with all your records, only after a complete examination a doctor can correctly evaluate you for surgery. In general At 4 cm we can ask a patient to wait but if symptoms are getting worse, dilation is getting worse, patient ha other co morbid which might make his condition worse, we ask for surgery sooner. I hope this answered your question, If you have more queries I am happy to answer you. Regards.
