Use of enoxaparin for the chronically anticoagulated patient before and after procedures.

Patients who require chronic anticoagulation and a procedure have been traditionally managed either by stopping warfarin and starting intravenous standard heparin or by adjusted dose subcutaneous standard heparin or taken off all anticoagulation for a week before the procedure. Enoxaparin may be useful as an alternative method of anticoagulation, avoiding hospitalization and the need for frequent monitoring.
