Any experience with abdominal aortic aneurysm surgery?

UPDATE: the surgery went well amd she is recovering now

I talked in the past about my mother here.

She's been diagnosed with abdominal aortic aneurysm and keeping an eye on it.

Now it's time for surgery because it's big and in danger of rupture.

She's already in the hospital and will operate today or tomorrow.

She is still frail and eating less since my brother's death. Weight is only 44k/97lbs. She is 74 years old.

I keep reading that the endovascular surgery is not that dangerous. Just a minor cut in the groin, but I'm really afraid due to her weakness. Doctor assured is OK and he is the best in town. Last year he did 25 of these and this year 15.

Guess I'm just venting and afraid. Lost a brother a year and half ago and now it's my mother.

Feels like I'm just living between tragedies.
