DBS and previous blood clots

I have a complicated history of blood clots that put my scheduled dbs on hold for over 1.5 years. I'm now eligible for the surgery but at an extremely high risk of blood clots. Has anyone been in a similar situation and how did you get thru? What was done prior to keep blood clots from going to heart lung and brain while off blood thinners before surgery and in between? How long does the risk of blood clots remain high after dbs? Thank you!
