title: Utility of multidetector-row computed tomography and ultrasonography for preoperative planning in a patient with a history of a right gastroepiploic artery CABG undergoing a laparoscopic cholecystectomy.
abstract: BACKGROUND
  Laparoscopic cholecystectomy has become the standard procedure for acute cholecystitis.
  
  
  METHODS
  This procedure, however, is challenging to perform in patients who have had coronary artery bypass grafting (CABG) using the right gastroepiploic artery (RGEA).
  
  
  RESULTS
  We completed a laparoscopic cholecystectomy for acute cholecystitis without intraoperative or postoperative cardiac complications in a patient with a history of an RGEA CABG.
  
  
  CONCLUSIONS
  A critical factor for avoiding disruption to the graft was preoperatively delineating the vascular anatomy of the RGEA graft with a multidetector-row computed tomography (CT) with 3D-CT angiography and ultrasonography.
