My (34 year old) exwife says she neads a medical procedure that consists of removinig viens from her legs that are putting her circulatory system at risk. I´ve never heard of this. Is it true?

Yes, there is surgery for that. It is usually done for varicose veins. But since you cannot provide much information, I do not know what your ex wife is going to have done or why.

But if you think she was just blowing smoke in your face - there is a real surgery for removing veins.

Vein ligation and stripping (http://www.webmd.com/a-to-z-guides/vein-ligation-and-stripping)

HOWEVER do not take this to mean that I believe this is what your ex wife has. It is just food for thought. Ask her!

Ok thank you for the response and the link. I don´t doubt it´s valid but it surprises me that some one that age would need such a thing.

It depends on the situation. Did she give you a name of the condition she is experiencing? Has she had issues with blood clots? Numbness? Discoloration? Leg ulcers?

Sometimes it can be discomfort, but not necessarily a true health concern.

First time I hear such thing..
Wow
