Thrombosis

How do you manage low versus intermediate/high risk deep venous thrombosis patients pre-and post-
op with respect to warfarin dosing?

Low risk preop discontinue warfarin for 5 days before surgery with no bridging required
Low risk postoperative restart 24 hours post with LMWH bridge
Intermediate and high-risk preoperative discontinue warfarin for 5 days and use low molecular weight
heparin bridge

Intermediate and high-risk postoperative restart warfarin 24 hours post surgery and bridge with low
molecular weight heparin
