When simple extractions can continue therapy and when to use short conservative holds based on drug, procedure risk, INR/CrCl, and neuraxial context.
No anticoagulant dosing with a catheter in place; earliest restart is removal plus interval (LMWH +4 h; UFH +1 h; longer for DOACs). Baseline windows still apply.
