I had done varicose veins surgery. How many days the drain will come and why?

It is unusual to have a drain left in place following vein surgery so there must have been a reason to place the drain.  A genereal rule of thumb for removing drains is to remove them when the drainage either stops or reduces to a minimal amount.  Speak with your surgeon about the drain.

Thanks for your question.  Unfortunately we do not see this treatment here.  It is a very long time to have a drain in place. Everything is done with laser through tiny punctures (incisions) under local anesthetic.  Are you able to research somewhere to see a vascular surgeon for an opinion?  I wish you well. Sorry I cannot help you.
