title: Uneventful removal of an epidural catheter guided by impedance aggregometry in a patient with recent coronary stenting and treated with clopidogrel and acetylsalicylic acid.
abstract: OBJECTIVE
  This report suggests that impedance aggregometry can be helpful to assess optimum time for and minimize the risk of catheter removal during double antiplatelet therapy.
  
  
  METHODS
  A 52-year-old patient undergoing cystectomy during combined general and epidural anesthesia suffered an acute myocardial infarction, and required coronary artery stenting and dual antiplatelet function therapy.
  
  
  CONCLUSIONS
  Balancing the risks of stent occlusion and epidural bleeding, bedside impedance aggregometry helped to identify the optimum time window for epidural catheter removal with the lowest bleeding risk in this patient.
