Hey
I have 2 Blood Disorders (Factor V & Prothrombin 2021 Mutation), have had many numerous blood clots in both my legs, lungs, and heart, it is definitely a big under taking and making sure they can keep you having a regular PT-INR before and mainly after surgery. You will definitely need to have your surgeon and hematologist team up and work out your lovenox schedule, pre and post op. It is absolutely possible, but you need good/caring docs to get you through it. Good Luck & I hope it works out for you!
