The 'easy' answer to your question about other surgeries would be to suggest doing a Search on VR for keyword "bridging".
Most Surgeons will want their patients to go OFF Coumadin / Warfarin several days before the procedure. I asked 3 CardioThoracic Surgeons about their Bridging Protocol and got 3 different answers.
1 - NO Bridging, just go off X days before (typically 3 to 5) and resume the same night as the surgery.
2 - Stop Coumadin X days before, Start Lovenox (Low Molecular Weight Heparin) Injections 1 day later, every 12 hours, until 24 hours before the surgery. Then Stop the Lovenox. Resume Coumadin the same night after surgery, knowing that it takes 3 to 4 days to become fully effective. Do NOT resume Lovenox Briding.
3 - Stop Coumadin X days before, Start Lovenox Injections 1 day later, every 12 hours, until 24 hours before the surgery. Then Stop the Lovenox. Resume Coumadin the same night after surgery. Resume Lovenox Injections somewhere between ~6 hours and 48 hours following the surgery, depending on the Surgeons assessment of Bleeding Risk versus Stroke Risk.
It is wise to have your Cardiologist confer with the surgeon about the Bridging Protocol, regardless of which one is chosen. Whoever manages your anticoagulation would likely be the person to set up the Bridging Schedule and teach you how to do the injections (to your fatty abdomen area).
