Yep. I have more than 20 of them from my mastectomy. And I never even set off the airport security alarms!

I doubt they were left by mistake. I had major abdominal surgery nearly 3 years ago, and my surgical clips still show up on all my x-rays and CT scans. From what I know, they use them to pinch off bleeding blood vessels.
Hope this helps...
