[Removal of epidural catheter under dual antiplatelet therapy following acute coronary syndrome : scenario without special consideration to the current guidelines on epidural regional anesthesia].
This article reports the case of a patient who developed acute coronary syndrome while receiving postoperative pain treatment via an epidural catheter (EC). Platelet function testing was performed before removal of the EC to assess the bleeding risk under ongoing dual antiplatelet therapy. Platelet function testing showed low responsiveness to clopidogrel and acetylsalicylic acid (ASS). The EC was removed uneventfully and clopidogrel was subsequently replaced by prasugrel and platelet function showed improved depression of thrombocyte aggregation. Possible reasons for low responsiveness to clopidogrel and ASS, such as drug-drug interactions with proton pump inhibitors and genetic factors are discussed.
