Thoracic Aortic Aneurysm and a colonoscopy

Posted by sbest010 @sbest010, Nov 22, 2025

I am inquiring about people's experience that have been diagnosed with a thoracic aortic aneurysm and have underwent a colonoscopy.

My concern lies with the fact that during a colonoscopy the vagal nerve is impacted and this can directly impact heart rate and blood pressure impeding the aorta.

I understand this is a rare complication but I was wondering the experiences people have had and any precautions their physicians might of advised.

To be extra careful, I am having the colonoscopy at the hospital instead of the outpatient clinic but was wondering if there is anything else I should consider.

Thank you

I didn't know I had an Ascending Aortic Aneurysm but still had a colonoscopy while I had one and there was no issue. There was no mention of that being and issue when I still had the aneurysm.

After my surgery, I now have to take antibiotics if I have one but that is concern over the material they replaced my root and ascending aorta.

I have a thoracic aortic aneurysm (ascending). The gastroenterologist required a written clearance from my cardiologist before proceeding with my colonoscopy. Cardiologist did not have concerns with the procedure and provided the clearance without conditions. No complications during my colonoscopy.

@It sounds like your gastro enterologist is worried about the wrong end?
