Clips Showing on X-Ray, do they dissolve?

The most common reason to use surgical clips is when we want to control bleeding from larger blood vessels. They are a reasonable alternative to using sutures or electrocautery to control bleeding. The clips are permanent and made of non-iron (thus non-magnetic) materials - usually titanium. There is no reason for concern with MRIs or "migration" of the clips. The bottom line is this - Don't worry, they are harmless.

If the clips can be seen on an xray, they are metal. It is not uncommon to use clips when dealing with small bleeding vessels, and metal ones are the more common ones to use. They are permanent, and harmless. It is obvious what they are and should not interfere with any chest or breast imaging you may need in the future. 

All the best.
